How can I get the application's path in a .NET

Question

How do I find the application's path in a console application?

In Windows Forms, I can use Application.StartupPath to find the current path, but this doesn't seem to be available in a console application.

Answer 1

Try this simple line of code:

 string exePath = Path.GetDirectoryName( Application.ExecutablePath);

Answer 2

Here is a reliable solution that works with 32bit and 64bit applications.

Add these references:

using System.Diagnostics;

using System.Management;

Add this method to your project:

public static string GetProcessPath(int processId)
{
    string MethodResult = "";
    try
    {
        string Query = "SELECT ExecutablePath FROM Win32_Process WHERE ProcessId = " + processId;

        using (ManagementObjectSearcher mos = new ManagementObjectSearcher(Query))
        {
            using (ManagementObjectCollection moc = mos.Get())
            {
                string ExecutablePath = (from mo in moc.Cast<ManagementObject>() select mo["ExecutablePath"]).First().ToString();

                MethodResult = ExecutablePath;

            }

        }

    }
    catch //(Exception ex)
    {
        //ex.HandleException();
    }
    return MethodResult;
}

Now use it like so:

int RootProcessId = Process.GetCurrentProcess().Id;

GetProcessPath(RootProcessId);

Notice that if you know the id of the process, then this method will return the corresponding ExecutePath.

Extra, for those interested:

Process.GetProcesses() 

...will give you an array of all the currently running processes, and...

Process.GetCurrentProcess()

...will give you the current process, along with their information e.g. Id, etc. and also limited control e.g. Kill, etc.*

You may be looking to do this:

System.IO.Path.GetDirectoryName(
    System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase)

Answer 4

I mean, why not a p/invoke method?

    using System;
    using System.IO;
    using System.Runtime.InteropServices;
    using System.Text;
    public class AppInfo
    {
            [DllImport("kernel32.dll", CharSet = CharSet.Auto, ExactSpelling = false)]
            private static extern int GetModuleFileName(HandleRef hModule, StringBuilder buffer, int length);
            private static HandleRef NullHandleRef = new HandleRef(null, IntPtr.Zero);
            public static string StartupPath
            {
                get
                {
                    StringBuilder stringBuilder = new StringBuilder(260);
                    GetModuleFileName(NullHandleRef, stringBuilder, stringBuilder.Capacity);
                    return Path.GetDirectoryName(stringBuilder.ToString());
                }
            }
    }

You would use it just like the Application.StartupPath:

    Console.WriteLine("The path to this executable is: " + AppInfo.StartupPath + "\\" + System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe");

Answer 5

You can use the following code to get the current application directory.

AppDomain.CurrentDomain.BaseDirectory

Answer 6

in VB.net

My.Application.Info.DirectoryPath

works for me (Application Type: Class Library). Not sure about C#... Returns the path w/o Filename as string
