Question

Let’s say I have a folder like ClientBin in my Visual Studio C# Web Application.

I’m confused as to what the @”” will do in the following C# code that tries to create a path to a Directory:

String DirectoryPath = System.IO.Path.Combine(@"" + "ClientBin");

Or when it comes to fa file like in the following example:

String FilePath = System.IO.Path.Combine("admin", "access", @"" + "users.aspx");

Basically, could someone please explain to me what the @”” has to do with the System.IO.Path.Combine method?

Answer 1

Adding @ means that any escape character sequences are ignored and the string is taken as it is written. Not quite, see the link below.

@”C:\temp\file.txt”

is the same as

“C:\\temp\\file.txt”

In the second case \\ sequence means escaped backslash character.

update: dtb is right about that
