How to check if a program is using .NET?

Question

0.00/5 (No votes)

See more:

I am trying to determine if a launched application was built using .NET. I can use either C Sharp or VB.

What I have tried:

I found a solution on Stack Overflow, but the solution does not seem to work anymore. So I broke the solution method apart and did a Console.WriteLine() for each of the module names. The two modules that the solution looks for aren't listed and the modules that are loaded are: ntdll.dll, wow64.dll, wow64win.dll, wow64cpu.dll.
Any Help would be appreciated.

Solution 1

Use ildasm.exe (third answer in the SO question you linked to).

Programmatically, you can try to load the assembly:

C#

public static bool IsAssembly(string absolutePath)
{
   try
   {
      Assembly assembly = Assembly.LoadFile(absolutePath);
      return true;
   }
   catch (Exception _)
   {
      return false;
   }
}

I am looking for a boolean method, with the parameter either the file path or the process of the application. Something similar to the solution with 41 votes on SO.
