Question

I’ve written a wrapper for a 3rd party exe. The exe is in a folder inside my class library project and is deployed with the dll.

Unit testing the method that starts the process containing this exe works fine but when I use the dll inside by web application, the exe cannot be found.

Debugging I see that the path to the exe is not correct when used from my web application.

I’ve tried:

string processPath = Path.Combine(Environment.CurrentDirectory, @"folder\file.exe");

and

string processPath = Path.GetFullPath(@"folder\file.exe");

as well as simply:

var processStartInfo = new ProcessStartInfo(@"folder\file.exe");

Is there something I can use to refer to the folder relative to where the dll is stored (i.e. in the bin for my web app)?

Answer 1

Executable:

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

.dll

string path = Path.GetDirectoryName(Assembly.GetAssembly(typeof(MyClass)).CodeBase);

might need

using System.IO;
using System.Windows.Forms;
using System.IO;
using System.Reflection;

Or You can use:

You can merge the exe and the dlls with the ILMerge.exe tool

lmerge.exe /out:C:\SomePath\TheOnlyOneExe.exe 
C:\....\bin\Debug\someexe.exe C:\....\bin\Debug\somedll.dll /t:exe
