C# string 与Ascii码转换问题

[yigemingzi1024]

谁能提供一个ascii码转换为C# string的方法啊？

private string StringToAscii(string s)
{
string ascii = "";

foreach (char c in s)
{
int sss = (int)c;
ascii += sss.ToString() + ",";
}

if (ascii.Length > 0)
{
ascii = ascii.Substring(0, ascii.Length - 1);
}

return ascii;

}

/// <summary>

/// <param name="ascii"></param>
/// <returns></returns>
private string AsciiToString(string ascii)
{
string returnValue = "";
string[] split = ascii.Split(',');
foreach (string s in split)
{
returnValue += Encoding.ASCII.GetString(new byte[] { (byte)int.Parse(s) });
}
return returnValue;
}

这个是十进制的吧？

好像ascii码是对应字符的吧？

string s = "73F57A8CDFF0E671F6C607";
“S”是十六进制的ASCII码，怎样将"S"转换成正常的字符。
