不同项目（程序集）之间的反映

Question

Is there any way, from a given project, to create instances of classes contained in other projects ?

I usually use Assembly.GetExecutingAssembly().CreateInstance() , but obviously, this call will return NULL as the class I'm specifying is held in another project.

Any ideas ?

Answer 1

If you really want to use reflection to achieve this then look at Assembly.LoadFrom() . http://msdn.microsoft.com/en-us/library/system.reflection.assembly.loadfrom.aspx Alternatively, as someone pointed out, you can simply use project references.

You'll probably want to use Assembly.LoadFrom() to load the assembly from a file if you're trying to do reflection.

But if you simply want to use objects in the assembly, add the assembly as a reference to your project (right click the project in Solution Explorer, and click "Add Reference"). Then you can simlpy use all public objects from the referenced assembly.
