Unload a DLL loaded using DllImport

Question

How do I unload a DLL which has been loaded using DllImport in C#?

Answer 1

This should free a module previously loaded when you called P/Invoke function.

[DllImport("kernel32", SetLastError=true)]
static extern bool FreeLibrary(IntPtr hModule);

public static void UnloadModule(string moduleName)
{
    foreach(ProcessModule mod in Process.GetCurrentProcess().Modules)
    {
        if(mod.ModuleName == moduleName)
        {
            FreeLibrary(mod.BaseAddress);
        }
    }
}
