What does @"../.." mean in a path?

Question

I am following this tutorial from MSDN.

There's something I saw in the code that I can't understand

    private void PopulateTreeView()
    {
        TreeNode rootNode;

        DirectoryInfo info = new DirectoryInfo(@"../.."); // <- What does @"../.." mean?
        if (info.Exists)
        {
            rootNode = new TreeNode(info.Name);
            rootNode.Tag = info;
            GetDirectories(info.GetDirectories(), rootNode);
            treeView1.Nodes.Add(rootNode);
        }
    }

Answer 1

@ is for verbatim string, so that the string is treated as is. Especially useful for paths that have a \ which might be treated as escape characters ( like \n)

../.. is relative path, in this case, two levels up. .. represents parent of current directory and so on.

Answer 2

.. is the container directory. So ../.. means "up" twice.
For example if your current directory is C:/projects/a/b/c then ../.. will be C:/projects/a

Not the downvoter but . represents the current directory and .. would be one level up, maybe someone was upset reading your first line and hence voted you down – Peanuts

Pretty sure it's because the OP knows what ../.. means; he didn't know what @ means. It's the combination that threw him off, especially because the @ is redundant here anyway. – Simmons

Answer 3

example E:\Software\file\folder

/ is the root of the current drive. ./ is the current director. ../ is the parent of the current directory. that is ->E:\ ../.. is relative path, in this case, two levels up. to get folder just write "../../folder"

Answer 4

new DirectoryInfo(@"../..") means "a directory two levels above the current one".

The @ denotes a verbatim string literal.
