我发现回答这个问题的最接近的事情是使用for循环将几个字符串输入转换为数组。
我只想取1个字符串并将前7个数字转换为int数组。
此代码采用字符的整数值,然后根据Unicode值对它们进行测试,如果有效则返回true,否则重新生成while循环并再次请求输入。当我使用Console.Read();方法,并首先输入一个无效值,它会说我的代码在7次迭代中无效。这意味着即使字符串具有有效输入,console.Read()也必须再运行7次。
public static void GetDigits(ref int[] callNumberArray, ref bool valid)
{
Console.WriteLine("Please enter the code you wish to dial.");
while ( valid == false)
{//This loop will reiterate the read() function if the code is not valid.
valid = true;
for (int i = 0; i < 7; i++ )
{
if (i != 6 && i!= 5 && i != 5 && i != 4 && i != 3 && i != 2 && i != 1 && i != 0)
{
i = 0;
}
callNumberArray[i] = Console.Read();// I want to change this
}
for (int i = 0; i < 7; i++)
{
if (i != 6 && i != 5 && i != 5 && i != 4 && i != 3 && i != 2 && i != 1 && i != 0)
{
i = 0;
}
if (callNumberArray[0] == 53)
{
valid = false;
}
if (callNumberArray[i] < 49)
{
valid = false;
}
if (callNumberArray[i] > 57 && callNumberArray[i] < 65)
{
valid = false;
}
if (callNumberArray[i] > 90 && callNumberArray[i] < 97)
{
valid = false;
}
if (callNumberArray[i] > 122)
{
valid = false;
}
}
if (valid == false)
{
Console.WriteLine("You entered an invalid code. Please re-enter your code.");
}
}

我认为你应该使用正则表达式,例如:
MatchCollection matchList = Regex.Matches(Content, Pattern);
var list = matchList.Cast<Match>().Select(match => match.Value).ToList();

我只想取1个字符串并将前7个数字转换为int数组。
for(int i = 0; i < n; i++){
obj = objectsArray[i];
objBox = obj.BoundingBox;
if ((B.Max.Z > objBox.Max.Z || B.Max.Z > objBox.Min.Z) && (B.Min.Z < objBox.Max.Z || B.Min.Z < objBox.Min.Z) && (B.Max.X > objBox.Max.X || B.Max.X > objBox.Min.X) && (B.Min.X < objBox.Max.X || B.Min.X < objBox.Min.X) && (B.Max.Y > objBox.Max.Y || B.Max.Y > objBox.Min.Y) && (B.Min.Y < objBox.Max.Y || B.Min.Y < objBox.Min.Y)) {
// obj is inside or overlapping box B
ObjectsInsideB.add(obj)
} else{
// obj out of box B
}
}
// objBox.Max bounding box vertex at maximum end
// objBo.min bounding box vertex at minimum end
基本上,如果你想逐字逐句地做到这一点,那么使用{{1来检查一个数字要容易得多或者正则表达式string subString = Console.ReadLine().Substring(0,7);
//Check if the whole string is a parsable number
if(int.TryParse(subString) == false)
{
Console.WriteLine("Not a valid number...");
return;
}
//convert it an int[]
int[] values = subString.ToCharArray().Select( value => int.Parse(value.ToString())).ToArray();
(每个字符),如果你对此很有帮助。

不确定&#34;算法&#34;你写了,我同意谢尔盖别列佐夫斯基的看法,看起来很奇怪,无论如何这应该回答你的具体问题:
public static void GetDigits(ref int[] callNumberArray, ref bool valid)
{
Console.WriteLine("Please enter the code you wish to dial.");
while ( valid == false)
{//This loop will reiterate the read() function if the code is not valid.
valid = true;
for (int i = 0; i < 7; i++ )
{
if (i != 6 && i!= 5 && i != 5 && i != 4 && i != 3 && i != 2 && i != 1 && i != 0)
{
i = 0;
}
callNumberArray[i] = Console.Read();// I want to change this
}
for (int i = 0; i < 7; i++)
{
if(!valid) break;
if (i != 6 && i != 5 && i != 5 && i != 4 && i != 3 && i != 2 && i != 1 && i != 0)
{
i = 0;
}
if (callNumberArray[0] == 53)
{
valid = false;
}
if (callNumberArray[i] < 49)
{
valid = false;
}
if (callNumberArray[i] > 57 && callNumberArray[i] < 65)
{
valid = false;
}
if (callNumberArray[i] > 90 && callNumberArray[i] < 97)
{
valid = false;
}
if (callNumberArray[i] > 122)
{
valid = false;
}
}
if (valid == false)
{
Console.WriteLine("You entered an invalid code. Please re-enter your code.");
}
}

这是一种方法,提示用户输入电话号码,拒绝无效字符,并显示当前电话号码和占位符,以便输入数字:
var nice = $("html").niceScroll({
scrollspeed: 60,
zindex: "999999",
background: "#fff",
mousescrollstep: 40,
cursoropacitymin: 0,
cursoropacitymax: .5,
cursorwidth: 15,
cursorborder: 0,
cursorcolor: '#000',
cursorborderradius: 6,
autohidemode: false,
horizrailenabled: false
});
提示输入:
private static int[] GetPhoneNumber(int phoneLength = 7)
{
List<int> phoneNumbers = new List<int>();
while (true)
{
EditorFor("Phone", String.Concat(phoneNumbers), phoneLength);
var key = Console.ReadKey(intercept: true);
if (key.Key == ConsoleKey.Escape)
return new int[0]; // return empty array if user cancelled input
var c = key.KeyChar;
if (!Char.IsDigit(c))
continue;
phoneNumbers.Add(Int32.Parse(c.ToString()));
if (phoneNumbers.Count == phoneLength)
{
EditorFor("Phone", String.Concat(phoneNumbers), phoneLength);
return phoneNumbers.ToArray();
}
}
}
用法:
private static void EditorFor(string label, string value, int length)
{
Console.SetCursorPosition(0, Console.CursorTop);
Console.Write(new String(' ', Console.WindowWidth));
Console.SetCursorPosition(0, Console.CursorTop);
int charactersLeftToInput = length - value.Length;
string placeholder = new String('*', charactersLeftToInput);
Console.Write("{0}: {1}{2}", label, value, placeholder);
Console.CursorLeft -= charactersLeftToInput;
}

好的,经过深思熟虑,我决定为数组中的每个元素使用一个单独的while ( valid == false)
{
valid = true;
callNumberArray[0] = Console.Read();
callNumberArray[1] = Console.Read();
callNumberArray[2] = Console.Read();
callNumberArray[3] = Console.Read();
callNumberArray[4] = Console.Read();
callNumberArray[5] = Console.Read();
callNumberArray[6] = Console.Read();
//etc etc...
