Dynamically invoking any function by passing function name as string

Question

How do I automate the process of getting an instance created and its function executed dynamically?

Thanks

Edit: Need an option to pass parameters too. Thank

I think your problem is little too generic here, I am providing a solution with certain assumptions here.

Assumption: you have a typeName (string), methodName (string), and a parameter (of SomeType).

public static void InvokeMethod(string typeName, string methodName, SomeType objSomeType) {
      Type type = Type.GetType(typeName);
      if(type==null) {
        return;
      }
      object instance = Activator.CreateInstance(type); //Type must have a parameter-less contructor, or no contructor.   
      MethodInfo methodInfo =type.GetMethod(methodName, BindingFlags.Instance | BindingFlags.Public);
      if(methodInfo==null) {
        return;
      }
      methodInfo.Invoke(instance, new[] { objSomeType });  
    } 

let me know know if my assumptions are wrong.
