Adding integer arrays to list

Question

I have a list of integer arrays:

List<int[]> MyList = new List<int[]>();

When trying to add an array to this list like this:

MyList.Add({ i, j });

The program won't compile, however this it has no issue with

int[] k = { i, j };
MyList.Add(k);

Why is the first method not valid and is there a better way than the second to carry out this task?

{ i, j } is short syntax for creating a new array and currently it only works at declarations. you can not use the same syntax for creating array anywhere else.

you can write

MyList.Add(new[]{ i, j });

You can use this.

  MyList.Add(new int []{ i, j });

Use MyList.Add(new int[] { i, j });
