问题描述
是否可以将 Visual C++ 2010 中的新 lambda 表达式用作 CLR 事件处理程序?我试过以下代码:
Is it possible to use the new lambda expressions in Visual C++ 2010 as CLR event handlers? I've tried the following code:
SomeEvent += gcnew EventHandler(
[] (Object^ sender, EventArgs^ e) {
// code here
}
);
它会导致以下错误消息:
It results in the following error message:
错误 C3364:System::EventHandler":委托构造函数的参数无效；委托目标需要是指向成员函数的指针
error C3364: 'System::EventHandler' : invalid argument for delegate constructor; delegate target needs to be a pointer to a member function
我是在尝试不可能的事情，还是只是我的语法错误?
Am I attempting the impossible, or is simply my syntax wrong?
推荐答案
不行，C++/CLI 编译器没有更新以接受 lambda 语法.顺便说一句，考虑到托管代码的领先优势，这颇具讽刺意味.
No can do, the C++/CLI compiler didn't get updated to accept the lambda syntax. Fairly ironic btw given the head-start that managed code had.
