在托管C++中正确实现带事件的C#接口,可以按照以下步骤进行:
public interface IEventInterface
{
event EventHandler MyEvent;
void TriggerEvent();
}
#include <vcclr.h>
using namespace System;
public ref class ManagedClass : public IEventInterface
{
public:
virtual event EventHandler^ MyEvent;
virtual void TriggerEvent()
{
MyEvent(this, EventArgs::Empty);
}
};
class Program
{
static void Main(string[] args)
{
IEventInterface managedClass = new ManagedClass();
managedClass.MyEvent += MyEventHandler;
managedClass.TriggerEvent();
}
static void MyEventHandler(object sender, EventArgs e)
{
Console.WriteLine("Event triggered!");
}
}
这样,当调用TriggerEvent
方法时,托管C++类会触发事件,并在C#中进行处理。
