List object initialization

Question

I've got a basic conceptual doubt and have been looking for an answer for some time now. I've initialized a list in the following manner :

List<string> list = new List<string>() { "a", "b", "c" };

Just this once I missed the () and initialized it in the following manner instead :

List<string> list = new List<string> { "a", "b", "c" };

No compile time or run time error was thrown. so I want to know if the second method is right? And what is the difference between the two?

The `()` is optional, there is no difference. If you look at the IL it should be the same. — Travis J, Apr 24 '17 at 18:22
You have to use `()` when providing arguments to the constructor, otherwise can omit them when using object initializer. — dcg, Apr 24 '17 at 18:24

Both does the same job, where () is optional

In your first example, the compiler knows that you're calling the default constructor

  List<string> list = new List<string> { "a", "b", "c" };

In the second, you explicitly call the default constructor

  List<string> list = new List<string>() { "a", "b", "c" };
