在 C# 中,这两行代码有什么区别(如果有)?
In C#, what is the difference (if any) between these two lines of code?
tmrMain.Elapsed += new ElapsedEventHandler(tmrMain_Tick);和
tmrMain.Elapsed += tmrMain_Tick;两者的工作方式似乎完全相同.当您键入后者时,C# 是否只是假设您指的是前者?
Both appear to work exactly the same. Does C# just assume you mean the former when you type the latter?
推荐答案我做到了
static void Hook1() { someEvent += new EventHandler( Program_someEvent ); } static void Hook2() { someEvent += Program_someEvent; }然后在代码上运行 ildasm.生成的 MSIL 完全一样.
And then ran ildasm over the code. The generated MSIL was exactly the same.
所以回答你的问题,是的,它们是一回事.编译器只是推断你想要 someEvent += new EventHandler( Program_someEvent );-- 您可以在 MSIL 中看到它在两种情况下都创建了新的 EventHandler 对象
So to answer your question, yes they are the same thing. The compiler is just inferring that you want someEvent += new EventHandler( Program_someEvent ); -- You can see it creating the new EventHandler object in both cases in the MSIL
