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.

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

Thanks.

回答1:

You should assign result of replacement:

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

or

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

回答2:

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

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

回答3:

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