C＃中是否有一种类似于Java的方法来初始化锯齿状数组

Question

In Java, I can do the following:

String[][] map = {
        {"1.0, ", "1.1, ", "1.2, ", "1.3, ", "1.0, "},
        {"A, ", "B, ", "C, ", "D, ", "E, "},
        {"X, ", "XX, ", "XXX, ", "XXXX, ", "XXXX, "},
                     };

but the same code does not compile in C#. I could do it in a tedious way by initializing the sub-fields one by one but I am sure there is a better way.

Answer 1

The closest thing you can do in C# is to add new [] before each array initializer:

String[][] map = {
                    new [] {"1.0, ", "1.1, ", "1.2, ", "1.3, ", "1.0, "},
                    new [] {"A, ", "B, ", "C, ", "D, ", "E, "},
                    new [] {"X, ", "XX, ", "XXX, ", "XXXX, ", "XXXX, "},
                 };

Answer 2

Yes:

int[][] jaggedArray = new int[3][];

jaggedArray[0] = new int[5];
jaggedArray[1] = new int[4];
jaggedArray[2] = new int[2];
