How can I open Windows Explorer to a certain directory from within a WPF app?

Question

In a WPF application, when a user clicks on a button I want to open the Windows explorer to a certain directory, how do I do that?

I would expect something like this:

Windows.OpenExplorer("c:\test");

Answer 1

Why not Process.Start(@"c:\test");?

Answer 2

Process.Start("explorer.exe" , @"C:\Users");

I had to use this, the other way of just specifying the tgt dir would shut the explorer window when my application terminated.

Answer 3

This should work:

Process.Start(@"<directory goes here>")

Or if you'd like a method to run programs/open files and/or folders:

private void StartProcess(string path)
{
    ProcessStartInfo StartInformation = new ProcessStartInfo();

    StartInformation.FileName = path;

    Process process = Process.Start(StartInformation);

    process.EnableRaisingEvents = true;
}

And then call the method and in the parenthesis put either the directory of the file and/or folder there or the name of the application. Hope this helped!

Answer 4

You can use System.Diagnostics.Process.Start.

Or use the WinApi directly with something like the following, which will launch explorer.exe. You can use the fourth parameter to ShellExecute to give it a starting directory.

public partial class Window1 : Window
{
    public Window1()
    {
        ShellExecute(IntPtr.Zero, "open", "explorer.exe", "", "", ShowCommands.SW_NORMAL);
        InitializeComponent();
    }

    public enum ShowCommands : int
    {
        SW_HIDE = 0,
        SW_SHOWNORMAL = 1,
        SW_NORMAL = 1,
        SW_SHOWMINIMIZED = 2,
        SW_SHOWMAXIMIZED = 3,
        SW_MAXIMIZE = 3,
        SW_SHOWNOACTIVATE = 4,
        SW_SHOW = 5,
        SW_MINIMIZE = 6,
        SW_SHOWMINNOACTIVE = 7,
        SW_SHOWNA = 8,
        SW_RESTORE = 9,
        SW_SHOWDEFAULT = 10,
        SW_FORCEMINIMIZE = 11,
        SW_MAX = 11
    }

    [DllImport("shell32.dll")]
    static extern IntPtr ShellExecute(
        IntPtr hwnd,
        string lpOperation,
        string lpFile,
        string lpParameters,
        string lpDirectory,
        ShowCommands nShowCmd);
}

The declarations come from the pinvoke.net website.
