C# string - creating an unescaped backslash

I am using .NET (C#) code to write to a database that interfaces with a Perl application. When a single quote appears in a string, I need to "escape" it. IOW, the name O'Bannon should convert to O\'Bannon for the database UPDATE. However, all efforts at string manipulation (e.g. .Replace) generate an escape character for the backslash and I end up with O\\'Bannon.

I know it is actually generating the second backslash, because I can read the resulting database field's value (i.e. it is not just the IDE debug value for the string).

How can I get just the single backslash in the output string?

You can also use a verbatim string

s = s.Replace("'", @"\'");

even better assign a var to the replace so that you can check it as well if needed

var RepName = "O'Bannon";
var Repstr = RepName.Replace("'","\\'");

Well I did 

"O'Bannon".Replace("'","\\'")

and result is 

"O\'Bannon"

Is this what you want?

You can use "\\", which is the escape char followed by a backslash.
