string - Replace \ with in C#

Question

I have a long string (a path) with double backslashes, and I want to replace it with single backslashes:

string a = "a\b\c\d";
string b = a.Replace(@"", @"");  

This code does nothing...

b remains "a\b\c\d"

I also tried different combinations of backslashes instead of using @, but no luck.

Answer 1

Because you declared a without using @, the string a does not contain any double-slashes in your example. In fact, in your example, a == "acd", so Replace does not find anything to replace. Try:

string a = @"a\b\c\d";
string b = a.Replace(@"", @"");
