接口怎定事件啊
public class T1
{
public delegate void myEventHander(string a,string b);
public event myEventHander myEvent;
}

public class T2:T1,TInterface
{

}

public class T3:T1,TInterface
{
}

public interface TInterface
{
}
怎定接口TInterface ，另他可以用事件myEvent呢。各位大指教。Thank you very much.

[解决办法]
public delegate void myEventHander(string a,string b);

public interface ITInterface
{
event myEventHander TestEvent;
void OnTestEvent();
}

给你个建议...接口命名应以字母 I 打头...
[解决办法]
public interface ITInterface
{
event EventHander TestEvent;
}

接口内不允许有任何类似public ,private等修饰
