createinstance

The problem I have is that CreateInstance returns null. Here is the code: if(spattmono[0] != null) { if((SpecialAttack) System.Activator.CreateInstance( spattmono[0].GetClass()) == null) { Debug.Log("DUMB ACTIVATOR!!!"); } //combo.SetSpecialAttack(spattack); } Attack and SpecialAttack are both classes that store basic information, and inherit from UnityEngine.Object . Attmono and spattmono are both MonoScript arrays, attmono being able to hold 16 and spattmono being able to hold 4. They get there information from these. for(int at = 0; at < numberOfAttacks; ++at ) { attmono[at] = (MonoScript)

What I have now (which successfully loads the plug-in) is this: Assembly myDLL = Assembly.LoadFrom("my.dll"); IMyClass myPluginObject = myDLL.CreateInstance("MyCorp.IMyClass") as IMyClass; This only works for a class that has a constructor with no arguments. How do I pass in an argument to a constructor? You cannot. Instead use Activator.CreateInstance as shown in the example below (note that the Client namespace is in one DLL and the Host in another. Both must be found in the same directory for code to work.) However, if you want to create a truly pluggable interface, I suggest you use an

I have created an engine that takes in 3rd party plugins (DLL's) that implement an interface. Since I have no control over the code that gets plugged in, I want to be able to run 1 specific method (from the interface) from the correct class (GetTypes loop untill I find the interfaced class ). Since anyone can create nice constructor code that executes on Activator.CreateInstance , I can solve that by using FormatterServices.GetUninitializedObject . But that does not help when code is being initialized on fields in the class. public class myclass : myinterface { public someotherclass name = new

I need a performance enhanced Activator.CreateInstance() and came across this article by Miron Abramson that uses a factory to create the instance in IL and then cache it. (I've included code below from Miron Abramson's site in case it somehow disappears). I'm new to IL Emit code and anything beyond Activator.CreateInstance() for instantiating a class and any help would be much appreciative. My problem is that I need to create an instance of an object that takes a ctor with a parameter. I see there is a way to pass in the Type of the parameter, but is there a way to pass in the value of the

I want to create an instance of a type that I specify in a generic method that I have. This type has a number of overloaded constructors. I'd like to be able to pass arguments to the constructors, but Activator.CreateInstance<T>() doesn't see to have this as an option. Is there another way to do it? Yes. (T)Activator.CreateInstance(typeof(T), param1, param2); sudhAnsu63 There is another way to pass arguments to CreateInstance through named parameters. Based on that, you can pass a array towards CreateInstance . This will allow you to have 0 or multiple arguments. public T CreateInstance<T>

I'm trying to improve the performance of our application. We have a lot of Activator.CreateInstance calls that are causing some grief. We instantiate a lot of classes based on an interface (ITabDocument) and after looking around I thought of using this code: The code is no better (infact marginally slower) than using the Activator.CreateInstance code we had. public static Func<T> CreateInstance<T>(Type objType) where T : class, new() { var dynMethod = new DynamicMethod("DM$OBJ_FACTORY_" + objType.Name, objType, null, objType); ILGenerator ilGen = dynMethod.GetILGenerator(); ilGen.Emit(OpCodes
