Fail to invoke class in dynamic loaded DLL from windows service

This is my class in a C# DLL

namespace MyNS
{
    public class MyClass
    {
        public static int Execute(string logKey, 
                                  string key, 
                                  XmlNode xmlPars)
        {
            return 0
        }
    }
}

I load DLL at run time and load Class Type in to _type variable. But when I call the function Execute from a Windows service like this:

counter = (int)_type.InvokeMember("Execute", 
                                  BindingFlags.Public |
                                  BindingFlags.InvokeMethod | 
                                  BindingFlags.Static, 
                                  null, 
                                  null, 
                                  new object[] { 
                                                  logKey, 
                                                  Key, 
                                                  _xmlParams 
                                                });

I get "Exception has been thrown by the target of an invocation."
What did I do wrong here?

How you are loading the the DLL, can you please share the code to load the dlls dynamically.?

Here's the sample code.

Assembly assembly = Assembly.LoadFrom("ABC.dll");
object o = Activator.CreateInstance(assembly.GetType("ClassName"));
/// then invoke the method
