CreateObject等同于C＃4，动态关键字和后期绑定？ [英] CreateObject equivalent for C# 4, dynamic keyword, and late binding?

问题描述

如何在不引用库的情况下从程序标识符或ProgID（例如Word.Application）在C＃4.0中创建动态COM / OLE / ActiveX对象？

How do I create a dynamic COM/OLE/ActiveX object in C# 4.0 from a program identifier or ProgID (such as "Word.Application") without referencing a library?

在C＃3.5中，我必须编写类似

In C# 3.5 I'd have to write something like

Type comObjectType = Type.GetTypeFromProgID(progId, true);
Activator.CreateInstance(comObjectType);

在C＃4.0中有更简单的方法，所以我可以将它分配给一个类型的变量动态（使用动态关键字）？

Is there an easier way to do it in C# 4.0 so I can assign it to a variable of type dynamic (using the dynamic keyword)?

推荐答案

dynamic myTypeInstance = Activator.CreateInstance(Type.GetTypeFromProgID(typeName, true));

？

还有

dynamic myTypeInstance = Activator.CreateInstance("typeName", "assemblyName");
