如何在C＃中部分初始化3D数组？

Question

I need to initialise a 3 level array, I know the size of the 2 first levels but the last one is determined randomly and varies from array to array.

int[,,] myArray;

How can I initialise the 2 first levels yet leave the last one untouched ?

myArray = new int[sizeA, sizeB, ???];

Answer 1

Eg, array 3 x 5 x Variable_size:

        int[][][] myArray = new int[3][][];
        for (int i = 0; i < 3; i++)
            myArray[i] = new int[5][];

        myArray[0][0] = new int[5];
        myArray[0][1] = new int[6];
        myArray[0][2] = new int[3];
        myArray[0][3] = new int[2];
        myArray[0][4] = new int[7];
        myArray[1][0] = new int[3];
        //...
        myArray[2][4] = new int[9];

or

        int[,][] myArray = new int[3,5][];
        myArray[0, 0] = new int[3];
        myArray[0, 1] = new int[5];
        myArray[0, 2] = new int[2];
        myArray[0, 3] = new int[4];
        myArray[0, 4] = new int[6];
        myArray[1, 0] = new int[3];
        //...
        myArray[2, 4] = new int[8];

Usage accordingly:

myArray[0][1][3] = 5;
int a = myArray[1][0][2];

or

myArray[0, 1][3] = 5;
int a = myArray[1, 0][2];
