Executing another program from C#, do I need to parse the “command line” from registry myself?

Question

From the registry, for a given file type, I get a string containing something like this:

\"C:\\Program Files\\AppName\\Executable.exe\" /arg1 /arg2 /arg3
         


        

Answer 1

I had a similar problem (parsing a ClickOnce UninstallString from the registry to execute using System.Diagnostics.Process). I resolved it by removing tokens from the end of the uninstall string until I could detect a valid file path.

    public static string GetExecutable(string command)
    {
        string executable = string.Empty;
        string[] tokens = command.Split(' ');

        for (int i = tokens.Length; i >= 0; i--)
        {
            executable = string.Join(" ", tokens, 0, i);
            if (File.Exists(executable))
                break;
        }
        return executable;
    }
