Check if a DLL is present in the system

Question

quick question. I want to find out if a DLL is present in the system where my application is executing.

Is this possible in C#? (in a way that would work on ALL Wind

Answer 1

Actually it does not throw FileNotFoundException.

Also for that one needs to check in multiple places for path, for the LoadLibrary

There is a standard exception in .net the is derived from TypeLoadException, that is DllNotFoundException.

Best way is to wrap a method/PInvoke call in try..catch and handle the DllNotFoundException since .net will check for application path as well as any other paths set as part of PATH OS Environment variable.

[DllImport("some.dll")]
private static void SomeMethod();

public static void SomeMethodWrapper() {
try {
      SomeMethod();
    } catch (DllNotFoundException) {
    // Handle your logic here
  }
}
