问题 Assuming I have only the class name of a generic as a string in the form of "MyCustomGenericCollection(of MyCustomObjectClass)" and don't know the assembly it comes from, what is the easiest way to create an instance of that object? If it helps, I know that the class implements IMyCustomInterface and is from an assembly loaded into the current AppDomain. Markus Olsson gave an excellent example here, but I don't see how to apply it to generics. 回答1: Once you parse it up, use Type.GetType

问题 I´ve read 'C# anonymously implement interface (or abstract class)' thread for implementing an interface anonymously. But I wondered if this is also possible using .NET 2.0 (NO LINQ) using delegates or any similar approach. I know from JAVA the following possible: MyClass m = MyMethod(new MyInterface() { @override public void doSomething() {...} } (I hope I remember well, is a time ago that I used JAVA, but I suppose it was something similar). This might be helpful whenever a method needs an

问题 I would like advice on the best way to restrict access to a weba pplication (using .net 2.0 and II6) based on the clients IP address. The two ways I am considering: 1) Through the server side code - check the client I.P against a list of IP addresses within the web.config. 2) Through IIS by creating a virtual directory and restricting the I.P addresses on this virtual directory. My question is if I go the virtual directory route there are a lot of users that access this website and I have
