MyDllTest调用HwaRader.dll,在HwaRader.dll中有IIRader接口,IIviDriver是IIRader的父类,在IIviDriver中
通过属性的方式去调用Identity(即IIviDriverIdentity)的方法,但是却出现了错误,这是怎么回事呢??高手们
可以帮我解决一下吗?真的很感谢了~
在一个接口中通过属性访问调用另一个接口,真的需要耗费一定的精力啊!
请看“MyDllTest\Exe\MyDllTest.exe”,点击"TEST"将会出错

English:
MyDllTest call HwaRader.dll,There IIRader interface HwaRader.dll in,IIviDriver is IIRader's parent class,
I want to call Identity(IIviDriverIdentity) by the way of call the IIviDriver's property,But it was an error,
this is how it happened,Gurus, Can you help me solve it? I really appreciate the ~
In a call to another interface by other interface accessed via the property really takes some effort ah! ~
open “MyDllTest\Exe\MyDllTest.exe”,Click the "TEST" will be wrong。
