How to replace forward slash with backward slash in C#

How to replace forward slash with backward slash in C#

In C#, you can use the Replace method to replace forward slashes (/) with backward slashes (\) in a string. Here's an example:

string input = "C:/Users/username/Documents"; string output = input.Replace("/", "\\"); Console.WriteLine(output);

This will output C:\Users\username\Documents.

In the Replace method, the first argument is the character or string to be replaced (in this case, a forward slash), and the second argument is the replacement character or string (in this case, a backward slash). Note that because the backslash is a special character in C# string literals, you need to escape it with another backslash.

Alternatively, you can use the Path.Combine method to join directory or file names using the correct path separator for the current platform, like this:

string[] pathSegments = { "C:", "Users", "username", "Documents" }; string output = Path.Combine(pathSegments); Console.WriteLine(output);

This will output C:\Users\username\Documents. Path.Combine automatically uses the correct path separator (\ on Windows) for the current platform, so you don't need to manually replace slashes.
