Escape Sequence Issue with File Path: \ is stored as \\

I am trying to load the path of a file from registry but I am facing a problem, when I use \ in string, it is saved as \\ and when I use \\ (to make it \ in path string) it is also saved as \\. Here's what I am trying to do:

This is what I got when I went to debugging mode

Because of that \\ I always get null in key variable. How can I resolve this issue?

Any help will be appreciated.

  • Hi The problem is not the escape chars which windows will apply to all uri's

    The problem is with the opensubkey method, here you are submitting a key/value so the code you have is looking for a subkey of RibbonUi.xml which does not exist.

    Instead seperate the key/value lookup and all will work out fine.

                RegistryKey rkApp =
            Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true);

            if (rkApp.GetValue("MyTestRun_Key_Value") == null)
            {
                checkbox1.Checked = false;
            }

            else
            {
                checkbox1.Checked = true;
            }
