How does the code looks that would create an object of class:
string myClass = \"MyClass\";
Of the above type, and then call
Assuming that your class is in your executing assembly, your constructor and your method is parameterless.
Type clazz = System.Reflection.Assembly.GetExecutingAssembly().GetType("MyClass");
System.Reflection.ConstructorInfo ci = clazz.GetConstructor(new Type[] { });
object instance = ci.Invoke(null); /* Send parameters instead of null here */
System.Reflection.MethodInfo mi = clazz.GetMethod("MyMethod");
mi.Invoke(instance, null); /* Send parameters instead of null here */
