UnRecognised escape sequence in a string is throwing error in the replace method of the string

I have a string name which has - as a special character which has to be replaced by \-.

 name = name .Contains('-') ? name .Replace('-', '\-') : name;

The replace method throws error of unrecognized escape sequence.

When i try to do this

name = name .Contains('-') ? name .Replace('-', '\\-') : name;

too many characters in character literal.

Some example of name is :

abc-123-45g
xyz-1-2-3
ref-124

What is the best way to replace the character?

Well \- is not a character. its a string.

So you should use the overload the takes strings not characters:

name = name.Contains('-') ? name.Replace("-", "\\-") : name;

Also you don't really need that Contains condition. So you end up with:

name = name.Replace("-", "\\-");
