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. Thanks

Do you just want to call a parameterless constructor to create the instance? Is the type specified as a string as well, or can you make it a generic method? For example:

// All error checking omitted. In particular, check the results // of Type.GetType, and make sure you call it with a fully qualified // type name, including the assembly if it's not in mscorlib or // the current assembly. The method has to be a public instance // method with no parameters. (Use BindingFlags with GetMethod // to change this.) public void Invoke(string typeName, string methodName) {     Type type = Type.GetType(typeName);     object instance = Activator.CreateInstance(type);     MethodInfo method = type.GetMethod(methodName);     method.Invoke(instance, null); } 

or

public void Invoke<T>(string methodName) where T : new() {     T instance = new T();     MethodInfo method = typeof(T).GetMethod(methodName);     method.Invoke(instance, null); }
