对象初始化过程中添加事件处理程序 [英] Add event handler during object initialization

问题描述

我需要通过一个实例的某些类型的方法的（这将在这一刻被创建）。这种类型提供了几个事件，我想订阅过它，所以我的代码如下所示：

I need to pass a instance (which will be created in this very moment) of a certain type to a method. This type offers several events which I'd like to subscribe to too, so my code looks like this:

var instance = new Instance();
instance.OnEvent1 += (sender, args) => {
    DoThis();
    DoThat();
}
instance.OnEvent2 += (sender, args) => DoThisToo();
instance.OnEvent3...
MyMethod(instance);

现在，是有可能在初始化过程中添加的处理程序？所以，我可以这样写：

Now, is it possible to add the handlers during initialization? So I can write something like this:

MyMethod((MyType)instance => {
    instance.OnEvent1 += (sender, args) => {
        DoThis();
        DoThat();
    }
    instance.OnEvent2...
});

这是当然只能期望的，因为化妆品的原因。我喜欢我的小代码&安培;可读的。

This is, of course only desired because of cosmetic reasons. I like my code small & readable.

推荐答案

这是不可能的，但现在根据的 罗斯林 该计划，并可能在未来推出。

This is not possible right now but according to Roslyn it is planned and might be available in the future.
