How to remove escape sequences from my string C#:

"\0EISO0160000500800822000000000000004000000000000000408150522100522001\u0001\a"

I want to delete these escape sequences:
"\0E"
"\u0001"
"\a"

I want to get my string of this way:

"ISO0160000500800822000000000000004000000000000000408150522100522001"

What I have tried:

String unescapedString = Regex.Unescape(textString);

string x = x.Replace("\"","");

Most probably too pragmatic:


        static void Main(string[] args)
        {
            string input = @"\0EISO0160000500800822000000000000004000000000000000408150522100522001\u0001\a";
            string deescaped= 
                input
                    .Replace(@"\0E", "")
                    .Replace(@"\u0001", "")
                    .Replace(@"\a", "");
            Console.WriteLine("Input: " + input);
            Console.WriteLine("Deescaped: " + deescaped);
            Console.ReadKey();
        }

You will need to do it manually and identify the sequence in each case. In your string you have three escape sequences that are all in different formats. So your code will need to examine each to identify how many characters following the backslash to remove.
