What is the best way to replace all occurrences of "" with "/" in a string in c#?

I've tried the following options but neither work.

You should assign result of replacement:

var res = variable. Replace("\\", "/"); //  you need "\\" because "\" is escape symbol.

or

var res = variable.Replace(@"\", "/");

As @UweKeim says in a comment, you have to store the result of the Replace call. Like this:

variable = variable.Replace("@"\", @"/");

This won't compile. – Uwe Keim Jan 30 '17 at 11:52
But this will... `var newVar = variable.Replace("\\", "/"); ' – Wudge Jan 30 '17 at 11:52
Why will it not compile? – Ben Jan 30 '17 at 11:53
@Ben. You've modified your code. See my comment for your original code: https://stackoverflow.com/posts/41935242/revisions – Uwe Keim Jan 30 '17 at 11:53
SO stripped my double backslash because it wasn't in code blocks, so i reformatted it.. – Ben Jan 30 '17 at 11:53
You need to escape the backslash. – IronAces Jan 30 '17 at 11:53

I did, but the original was without code blocks and SO removed the the backslash lmao, you guys are so judgemental, i literally fixed it within seconds – Ben Jan 30 '17 at 11:54
@Ben there's some sort of syntax crusader mentality on this site that can definitely be beneficial but feels so abused and overused – Jonesopolis Jan 30 '17 at 12:00
