Question

每次数字超过45时，如何将名称增加1？

简单地说，当我 NAME：45 时，我需要下一个名称为 NAME1：1 。它非常简单。但问题是，我已经有一个计数器来看看从45到1的变化。这是因为我不知道如何处理上述情况？我怎么能这样做？

我的代码段：

public void reccurent()
{ //Here we are exporting header
        string[] strLines = System.IO.File.ReadAllLines(textBox1.Text);
        string CarouselName = enter.Text;
        int[] cols = new int[] { 15, 15, 25, 15, 15 };
        StringBuilder sb = new StringBuilder();
        string[] cells = line.Replace("\"", "").Split('\t');
           //removing double woutes in the textfile
        for (int c = 0; c < cells.Length; c++)
            sb.Append(cells[c].Replace(" ", "_").PadRight(cols[c]));
                 //replacing all spaces with underscore in the header column
        sb.AppendLine("Location".PadRight(15));
        //adding a coumn called LOCATION
        sb.AppendLine();
        int repeater = 45; // change me
        int tmpCarousel = 0;
        int carouselNumber = 0;
        Dictionary<string, int> namesForCarousels = new Dictionary<string, int>();
        for (int i = 0; i < textfile.Count; i++)
        {
            for (int c = 0; c < cells.Length; c++)
                sb.Append(textfile[i].Cells[c].Replace(" ", "_").PadRight(cols[c]));
                   //replacing all spaces with underscore in each column values
            string name = textfile[i].Cells[1];

            if (namesForCarousels.TryGetValue(name, out tmpCarousel) == false)
            {
                carouselNumber++;
                if (carouselNumber > 45)
                    carouselNumber = 1;//resetting to number1, but name is

                namesForCarousels[name] = carouselNumber;
            }
            string num = carouselNumber < repeater ? "" : (carouselNumber / repeater).ToString();

            var strCorousel = lstMX.Find(x => x.MAX_PN.Equals(name)).Carousel;
            strCorousel = (String.IsNullOrEmpty(strCorousel)) ? CarouselName : strCorousel;
            sb.Append(String.Format("{0}:{1}", strCorousel + num, 1 + carouselNumber % repeater).PadRight(15));
           // carouselNumber++;
            sb.Append("\r\n");
        }
        System.IO.File.WriteAllText(@"D:\output.TXT", sb.ToString());
    }

输出为：

  NAME:2  // name is stating from2...
  NAME:3
  .
  .
  .
  NAME:45 //after the 45.. its going perfect to NAME1:1
  NAME1:1   //but after NAME1:1 its going to NAME
  NAME:2

这是一种方法。显然有很多方法可以做到这一点。

var testCounter = "NAME1";


for (int x = 0; x < 50; x++)
{
    Match m = Regex.Match(testCounter, @"(?<label>NAME)(?<counter>\d+)(?::(?<robinCounter>\d+))?");
    if (m.Success)
    {
        var count = Int32.Parse(m.Groups["counter"].Value);

        var roundRobinCounter = 0;
        if (m.Groups["robinCounter"].Success)
            roundRobinCounter = Int32.Parse(m.Groups["robinCounter"].Value);

        count++;
        if (count == 46)
        {
            count = 1;
            roundRobinCounter++;
        }

        var sb = new StringBuilder();
        sb.AppendFormat("{0}{1}", m.Groups["label"].Value, count);
        if (roundRobinCounter != 0)
            sb.AppendFormat(":{0}", roundRobinCounter);

        testCounter = sb.ToString();
        Console.WriteLine(testCounter);
    }
}

每次需要递增时，它只使用正则表达式来解析文本。我没有包含所有的错误处理，但你应该可以从这里拿起它。

这是正则表达式的细分

(?<label>           -- Start a named group capture called "label"
   NAME             -- Search for the literal "NAME"
)
(?<counter>         -- Start a named group capture called "counter"
   \d+              -- Search for one or more digits
)
(?:                 -- Start a non-capture group
:                   -- Find a literal colon, and stop the previous digit search
(?<robinCounter>    -- Start a named group capture called "robinCounter"
   \d+              -- Find one or more digits (continues to end of the string or when a non-didgit is found)
)
)?                  -- End the non-capture group, and make the group optional (the question mark means find 0 or 1 time)

编辑我更新了代码以反映您提供的输出。

以上代码中的一些示例输出：

NAME40
NAME41
NAME42
NAME43
NAME44
NAME45
NAME1:1
NAME2:1
NAME3:1
NAME4:1
NAME5:1
NAME6:1

Answer 2

示例3而不是45

int repeater = 3; // change me
string name = "NAME";
int carouselNumber = 0;

for (var i = 0; i < 50; i++)
{
    string num = carouselNumber < repeater ? ":" : (carouselNumber / repeater).ToString() + ":";
    Console.WriteLine("{0}\t{1}", name + num, 1 + carouselNumber % repeater);
    carouselNumber++;
}
