Word.Application myWord = new Word.ApplicationClass();
请问下面哪个最好，给出理由或者参考文献：

Word.Application myWord = new Word.Application();
Word.Application myWord = new Word.ApplicationClass();
Word.ApplicationClass myWord = new Word.Application();
Word.ApplicationClass myWord = new Word.ApplicationClass();
[解决办法]
public interface _Application
public interface Application : _Application, ApplicationEvents4_Event
public class ApplicationClass : _Application, Application,
Application继承了_Application。而ApplicationClass在2者基础上对event进一步增强。
如果只简单操作word，使用_Application, Application和ApplicationClass效果一致
