C# .NET - How to get the path of an Executable file using C#

Asked By suresh vsvb on 14-May-09 03:08 AM

Hi
I am having a Executable(Set.exe) and a DLL(some.dll). I am starting the application set.exe and which intern will calls the DLL(some.dll). I want to get the path of Set.exe from which it is started.
The condition is that i will write the command/call for getting the path of this EXE(Set.exe) in the DLL.So i want to get the path of EXE in the DLL and i will use this in the DLL later.

I am tried the methods getexecutingassembly and getentryassembly etc. But none of them worked for me.

Thanks for your ideas...

put the exe in your bin folder - Rao B replied to suresh vsvb on 14-May-09 03:16 AM

then try with getexecutingassembly

I cant put this in Bin. - suresh vsvb replied to Rao B on 14-May-09 03:22 AM

Hi

To Get executable start exe application path.

For Windows Forms Applications

string startpointPath = Application.ExecutablePath;

For Console level Applications.

string rootPath=System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location));

For the dll also you can use the  last code .

thank you

Getting only DLL path But not the Executable path - suresh vsvb replied to Ravenet Rasaiyah on 14-May-09 04:49 AM

string rootPath=System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location));

This one returning the DLL path but not the EXE path.

Hi

You need access Entry assembly to get path.

string rootPath=System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly().Location);

thank you

What is the class i should use - Asked By suresh vsvb on 14-May-09 05:11 AM

It seems i am not clear in using the Myclass. What is the Class i should use.

Do i have to use any Class that is defiend and used in the projects for Set.exe?

I already used this call - suresh vsvb replied to Ravenet Rasaiyah on 14-May-09 05:16 AM

I already used this one and it is not returning any path Neither DLL nor EXE.

I have mentioned this at the start of the post. Is the path from the EXE which we want is to be alive(needs to be running currently) i mean process?

Once can i recheck my question and let me know if u have any doubts in my requirement.

Thanks !

try using the ExecutablePath() or StartupPath() methods - H K replied to suresh vsvb on 14-May-09 04:23 PM

Try using the ExecutablePath() or StartupPath() methods to get the path of the current executing assembly.
This method is available in the Application class.

String aPath = Application.ExecutablePath();

sorry for the resurrection of this post :)

The property System.Windows.Forms.Application.ExecutablePath is exactly what you want.

I don't know why it's in the Windows.Forms namespace but ... works.

Alternatively I used System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName
