在对象初始化期间添加事件处理 [英] Add event handler during object initialization

问题描述

我需要将某种类型的实例（将在这个时刻创建）传递给一个方法。这种类型提供了我想订阅的几个事件，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，是否可以在初始化期间添加处理程序？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...
});

这当然是因为美观的原因而需要的。我喜欢我的代码小

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，但根据 Roslyn 它是计划的，可能在将来可用。

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