delegate{}和(输入参数)的区别=> {}
我有一些这样的方法
public void DoSomething(Action<int> action) { ... }
在某些情况下我不使用传递到操作中的参数。我应该注意这样称呼它
DoSomething(delegate { ... });
或
DoSomething(_ => { ... });
I have a few methods like this
public void DoSomething(Action<int> action) { ... }
In some cases I do not use the parameters passed into action. Are there any differences I should be aware of between calling it like this
DoSomething(delegate { ... });
or
DoSomething(_ => { ... });

不，它们是等价的。就我个人而言，我更喜欢
delegate {}因为很明显您不关心参数（甚至不命名它们），并且您不需要根据委托调整代码签名 - 但两者都很好。No, they're equivalent. Personally I prefer
delegate {}as it's obvious that you don't care about the parameters (to the extent of not even naming them), and you don't need to adapt the code based on the delegate signature - but both are fine.
