在C#中,这两行代码之间有什么区别(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;两者似乎工作正常。 C#只是假设你的意思是前者,当你输入后者?
Both appear to work exactly the same. Does C# just assume you mean the former when you type the latter?
推荐答案我这样做
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是完全相同的。
And then ran ildasm over the code. The generated MSIL was exactly the same.
所以要回答你的问题,是的,他们是一样的。 编译器只是推断你想要 someEvent + = new EventHandler(Program_someEvent); - 您可以看到它创建新的 EventHandler 对象在这两种情况下,MSIL
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
