Thread: Create Instance of Class from Class Name

Hey Guys,

Pretty much what I have is many many classes created, now the user will type a class name and a method and the application will run that method with the supplied arguments. Now I have got it working using:

Dim method As System.Reflection.MethodInfo

method = Type.GetType("Code." & Import).GetMethod(MethodName)

method.Invoke(<New Instance Of Class>, Arguments)

But I cannot find out how to create an instance of the class from a string.
'"Code." & Import' is that full class name that I want to create as I have used it in Type.GetType, but that is just getting the method from the class and I need to create an instance of the class to invoke that method.


Never mind guys, I've fixed it!
I used:

Assembly.GetExecutingAssembly().CreateInstance("Code." & Import)

and it seemed to work fine


Thanks,
Bryce Gough

Just as you're getting the appropriate MethodInfo from the Type and invoking it, so you can get the appropriate ConstructorInfo from the type and invoke that. Alternatively, you can also use the Activator.CreateInstance method.
