Question

我必须在c＃中每16个字符后添加或追加（逗号）。这段代码是.txt格式.plzz帮助一些示例代码如下：

我试过了

using (StreamReader reader = new StreamReader(fileStream))
{
    string linesFromFile = String.Concat(bin.Select(b => b.ToString("x2")));
    linesFromFile.Split(',');
    richTextBox1.Text = linesFromFile;
}

Answer 1

string input = "12345678";
StringBuilder sb = new StringBuilder();
for (int i = 0; i < input.Length; i++)
{
    if (i % 3 == 0)
        sb.Append(',');
    sb.Append(input[i]);
}
string formatted = sb.ToString();

Answer 2

您可以将StringBuilder用于此

s = "Your text";
StringBuilder result = new StringBuilder();
for (var i = 0; i<s.Length; i++)
{
    char currLetter = s[i];
    result = (i % 16 == 0) ? result.Append(string.Format(",{0}", currLetter)) : result.Append(currLetter);
}

Answer 3

一种简单的方法是：

        string result = string.Empty;
        for (int i = 0; i < text.ToArray().Length; i++)
        {
            char c = text.ToArray()[i];
            if (i%16 != 0)
                result += c;
            else
                result += "," + c;
        }

Answer 4

这有点短（而不是非常C＃-ish）：

string x = "that string", y = string.Empty; ; int i = -16;
while ( i < x.Length ) y += x.Skip( i += 16 ).Take( 16 ) + ",";

如果速度很重要，你应该考虑使用StringBuilder。

Answer 5

以下是基于输入的示例代码...

        var output = string.Empty;
        int count = 0;
        foreach (var c in input)
        {
            count++;
            output += count % 16 == 0 ? "," : c.ToString();
        }
