如何用棍棒获得用ascii艺术编码的数字？

数字在txt文件中，而且包含：

我必须得到被棍子淹没的小人物。

第一步是获得4行而不是用Alphabet控制它。

我在字符串[]

中获取文本

string[] lines = File.ReadAllLines("SourceFile.txt");

前4行符合第[3]行。我怎样才能控制同一位置的不同线？它就像一个二维数组，或者我必须做其他事情？

Answer 1

首先，您需要一个存储符号模式和指标的对象（在您的情况下为数字）。此对象还有一种在给定数组中识别其模式的方法：

public class AsciiNumber
{
    private readonly char[][] _data;

    public AsciiNumber(char character, char[][] data)
    {
        this._data = data;
        this.Character = character;
    }

    public char Character
    {
        get;
        private set;
    }

    public int Width
    {
        get
        {
            return this._data[0].Length;
        }
    }

    public int Height
    {
        get
        {
            return this._data.Length;
        }
    }

    public bool Match(string[] source, int startRow, int startColumn)
    {
        if (startRow + this.Height > source.Length)
        {
            return false;
        }

        for (var i = startRow; i < startRow + this.Height; i++)
        { 
            var row = source[i];
            if (startColumn + this.Width > row.Length)
            {
                return false;
            }

            for (var j = startColumn; j < startColumn + this.Width; j++)
            {
                if (this._data[i - startRow][j - startColumn] != row[j])
                {
                    return false;
                }
            }
        }

        return true;
    }
}

然后你可以创建像你处理的字母（我只使用数字1和3）：

public static class Alphabet
{
    private static readonly AsciiNumber Number1 = new AsciiNumber('1', new[]{
        new []{'|'},
        new []{'|'},
        new []{'|'},
        new []{'|'},
    });

    private static readonly AsciiNumber Number3 = new AsciiNumber('3', new[]{
        new []{'-','-','-'},
        new []{' ',' ','/'},
        new []{' ',' ','\\'},
        new []{'-','-','-'},
    });

    public static readonly IEnumerable<AsciiNumber> All = new[] { Number1, Number3 };
}

假设源文件中的数字具有permament和相等的高度，您可以尝试这样的代码：

        string[] lines = File.ReadAllLines("SourceFile.txt");
        var lineHeight = 4;

        var text = new StringBuilder();
        for (var i = 0; i < lines.Length; i += lineHeight)
        {
            var j = 0;
            while (j < lines[i].Length)
            {
                var match = Alphabet.All.FirstOrDefault(character => character.Match(lines, i, j));
                if (match != null)
                {
                    text.Append(match.Character);
                    j += match.Width;
                }
                else
                {
                    j++;
                }
            }
        }
        Console.WriteLine("Recognized numbers: {0}", text.ToString());

N.B。如果行高超过文件，则必须改进上面的代码。

Answer 2

假设我们有这个文本，我们想要解析其中的数字：

---       ---      |    |  |     -----   
 /         _|      |    |__|     |___    
 \        |        |       |         |   
--        ---      |       |     ____|

首先，我们应该删除任何不必要的空格（或tab，如果存在）并在数字之间放置一个分隔符char（例如$），获得类似于此的内容：

$---$---$|$|  |$-----$
$ / $ _|$|$|__|$|___ $
$ \ $|  $|$   |$    |$
$-- $---$|$   |$____|$

现在我们应该使用Split作为分隔符，在文本的每一行调用$函数，然后将结果与字母表进行比较。

让我们看看如何使用代码执行此操作。给定要解析string[] lines的文本，我们将创建一个扩展方法来删除不必要的空格并改为放置separator字符/字符串：

public static class StringHelperClass
{
    // Extension method to remove any unnecessary white-space and put a separator char instead.
    public static string[] ReplaceSpacesWithSeparator(this string[] text, string separator)
    {
        // Create an array of StringBuilder, one for every line in the text.
        StringBuilder[] stringBuilders = new StringBuilder[text.Length];

        // Initialize stringBuilders.
        for (int n = 0; n < text.Length; n++)
            stringBuilders[n] = new StringBuilder().Append(separator);

        // Get shortest line in the text, in order to avoid Out Of Range Exception.
        int shorterstLine = text.Min(line => line.Length);

        // Temporary variables.
        int lastSeparatorIndex = 0;
        bool previousCharWasSpace = false;

        // Start processing the text, char after char.
        for (int n = 0; n < shorterstLine; ++n)
        {
            // Look for white-spaces on the same position on
            // all the lines of the text.
            if (text.All(line => line[n] == ' '))
            {
                // Go to next char if previous char was also a white-space,
                // or if this is the first white-space char of the text.
                if (previousCharWasSpace || n == 0)
                {
                    previousCharWasSpace = true;
                    lastSeparatorIndex = n + 1;
                    continue;
                }
                previousCharWasSpace = true;

                // Append non white-space chars to the StringBuilder
                // of each line, for later use.
                for (int i = lastSeparatorIndex; i < n; ++i)
                {
                    for (int j = 0; j < text.Length; j++)
                        stringBuilders[j].Append(text[j][i]);
                }

                // Append separator char.
                for (int j = 0; j < text.Length; j++)
                    stringBuilders[j].Append(separator);

                lastSeparatorIndex = n + 1;
            }
            else
                previousCharWasSpace = false;
        }

        for (int j = 0; j < text.Length; j++)
            text[j] = stringBuilders[j].ToString();

        // Return formatted text.
        return text;
    }
}

然后，在Main方法中，我们将使用：

lines = lines.ReplaceSpacesWithSeparator("$");

和

ASCIINumbersParser parser = new ASCIINumbersParser(lines, "$");

其中ASCIINumbersParser是这个类：

public class ASCIINumbersParser
{
    // Will store a list of all the possible numbers
    // found in the text.
    public List<string[]> CandidatesList { get; }

    public ASCIINumbersParser(string[] text, string separator)
    {
        CandidatesList = new List<string[]>();

        string[][] candidates = new string[text.Length][];

        for (int n = 0; n < text.Length; ++n)
        {
            // Split each line in the text, using the separator char/string.
            candidates[n] =
                text[n].Split(new[] { separator }, StringSplitOptions.RemoveEmptyEntries);
        }

        // Put the strings in such a way that each CandidateList item
        // contains only one possible number found in the text.
        for (int i = 0; i < candidates[0].Length; ++i)
            CandidatesList.Add(candidates.Select(c => c[i]).ToArray());
    }
}

此时，我们将使用以下类生成某些数字的ASCII艺术表示，并将结果与原始字符串进行比较（在Main中）：

public static class ASCIINumberHelper
{
    // Get an ASCII art representation of a number.
    public static string[] GetASCIIRepresentationForNumber(int number)
    {
        switch (number)
        {
            case 1:
                return new[]
                {
                    "|",
                    "|",
                    "|",
                    "|"
                };
            case 2:
                return new[]
                {
                    "---",
                    " _|",
                    "|  ",
                    "---"
                };
            case 3:
                return new[]
                {
                    "---",
                    " / ",
                   @" \ ",
                    "-- "
                };
            case 4:
                return new[]
                {
                    "|  |",
                    "|__|",
                    "   |",
                    "   |"
                };
            case 5:
                return new[]
                {
                    "-----",
                    "|___ ",
                    "    |",
                    "____|"
                };
            default:
                return null;
        }
    }

    // See if two numbers represented as ASCII art are equal.
    public static bool ASCIIRepresentationMatch(string[] number1, string[] number2)
    {
        // Return false if the any of the two numbers is null
        // or their lenght is different.

        // if (number1 == null || number2 == null)
        //     return false;
        // if (number1.Length != number2.Length)
        //     return false;

        if (number1?.Length != number2?.Length)
            return false;

        try
        {
            for (int n = 0; n < number1.Length; ++n)
            {
                if (number1[n].CompareTo(number2[n]) != 0)
                    return false;
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error: " + ex);
            return false;
        }

        return true;
    }
}

最后，Main函数将如下所示：

static void Main()
    {
        string ASCIIString = @"
            ---       ---      |    |  |     -----   
             /         _|      |    |__|     |___    
             \        |        |       |         |   
            --        ---      |       |     ____|  ";

        string[] lines =
            ASCIIString.Split(new[] {"\n","\r\n"}, StringSplitOptions.RemoveEmptyEntries);

        lines = lines.ReplaceSpacesWithSeparator("$");

        ASCIINumbersParser parser = new ASCIINumbersParser(lines, "$");

        // Try to find all numbers contained in the ASCII string
        foreach (string[] candidate in parser.CandidatesList)
        {
            for (int i = 1; i < 10; ++i)
            {
                string[] num = ASCIINumberHelper.GetASCIIRepresentationForNumber(i);
                if (ASCIINumberHelper.ASCIIRepresentationMatch(num, candidate))
                    Console.WriteLine("Number {0} was found in the string.", i);
            }
        }
    }

    // Expected output:
    // Number 3 was found in the string.
    // Number 2 was found in the string.
    // Number 1 was found in the string.
    // Number 4 was found in the string.
    // Number 5 was found in the string.

Answer 3

我创建了所有模型并将其保存在字典中。
我将创建用于开发的目录 C：\ temp \ Validate C：\ temp \ Referenz C：\ temp \ Extract
在Dir参考中，将为字典中的每个模型创建一个文件。
我阅读了所有行，并将它们保存在字符串[]中。编码我将亲自从字符串[]到char [] []进行编码。完成此操作后，我们将在Dir中验证MyEncoding.txt文件，其中包含新号码列表。从上一个列表中，所有“ Char.Empty”（\ t）都转换为char null'\ 0'。
只要我从左到右逐列浏览列表，
我从列表中提取字符，具体取决于字典中Model的宽度（例如NumberOne的宽度为2，NumberFour的宽度为5）。每个摘录将保存在Dir Extract中的新文件中比较列表中的每个字符（如果相同）。如果它们有效，则提取的模型将保存在Dir Validated中的文件中，并带有识别的模型名称的名称，并使用记事本打开该文件几秒钟，此后记事本将关闭，搜索过程将重复进行，直到列表末尾。可以here找到这种方法的解决方案！
