I would basically create a static class that automatically pops up against any string. If the same is GUID, you can simply do 

Guid.NewGuid().ToString("N") returns only characters

Input: 12345678-1234-1234-1234-123456789abc Output: 12345678123412341234123456789abc 

    public static string ToNonDashed(this string input)
    {
        return input?.Replace("-", string.Empty);
    }

If you want to remove all non-numeric characters:

string result = Regex.Replace(inputString, @"[^0-9]", "");

Basically what that says is "if the character isn't a digit, then replace it with the empty string." The ^ as the first character in the character group negates it. That is, [0-9] matches any digit. [^0-9] matches everything except a digit. See Character Classes in the MSDN documentation.

The expression @"[^\d]" also would work

You can try this:

 Des_AccNo = Des_AccNo.Replace("-", string.Empty);

I don't know what is your code, but you can do that by:

val = val.Replace("-", string.Empty)
