Replace single backslash with double backslash

Question

It seems simple enough, right? Well, I don\'t know.

Here\'s the code I\'m trying:

input = Regex.Replace(input, \"\\\\\", \"\\\\\\\\\\\\\");
         


        

Answer 1

 var result = Regex.Replace(@"afd\tas\asfd\", @"\\", @"\\");

The first parameter is string \\ which is \ in regex.
The second parameter is not processed by regex, so it will put it as is, when replacing.
