如何制作一个整数数组的列表？

x

y

Point

class Point
{
    public readonly int X;
    public readonly int Y;
    public Point( int x, int y )
    {
        X = x;
        Y = y;
    }
}

y

x

List<Point> ls = new List<Point>();
ls.Add( new Point( 0, 0 ) );
ls.Add( new Point( 10, 10 ) );
ls.Add( new Point( 100, 100 ) );

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

l.Add(new int[] { 1, 2 });
l.Add(new int[] { 3, 4 });

int a = l[1][0];   // a == 3

        Int32 x = 1; 
        Int32 y = 2;

        // example of declaring a list of int32 arrays
        var list = new List<Int32[]> {
            new Int32[] {x, y}
        };

        // accessing x
        list[0][0] = 1;

        // accessing y
        list[0][1] = 1;

Int32[][] = new Int32[] { new Int32[] {1,2}, new Int32[] {3,4}};

Int32[,] = new Int32[,] {{1,2},{3,4}};

List<Tuple<int, int>> myList = new List<Tuple<int, int>>();

var item = new Tuple<int, int>(25, 3);

myList[0] = new Tuple<int, int>(20, 9);//acess to list items by index index

myList.Add(item);//insert item to collection

myList.IndexOf(item);//get the index of item

myList.Remove(item);//remove item from collection

List<List<int, int>>

List<int[]>

List<Tuple<int, int>>
