Answer 1

I just wrote this piece of code and it seems to work beautifully... It requires that the escape sequence is in HEX, and is valid for value's 0x00 to 0xFF.

// Example
str = remEscChars(@"Test\x0D") // str = "Test\r"

Here is the code.

private string remEscChars(string str)
{
   int pos = 0;
   string subStr = null;
   string escStr = null;

   try
   {
      while ((pos = str.IndexOf(@"\x")) >= 0)
      {
         subStr = str.Substring(pos + 2, 2);
         escStr = Convert.ToString(Convert.ToChar(Convert.ToInt32(subStr, 16)));
         str = str.Replace(@"\x" + subStr, escStr);
      }
   }
   catch (Exception ex)
   {
      throw ex;
   }

   return str;
}
