Hi there, i can initialize a two dimensional array:

int[,] myDimensional2 = new int[2, 3] { { 10, 20, 30 }, { 40, 50, 60} };

but i don't know how i can initialize a three, four,... dimensional arrays? :(

please initialize this array and give me the code, thank you so much :)

int[,,] threeDimensional = new int[2, 2, 3];

The array in your question has only one element, so you only need one value to completely initialise it. You need three sets of braces, one for each dimension of the array.
```
int min[1][1][1] = {{{100}}};
```
A clearer example might be:
```
int arr[2][3][4] = { 
```
```
{ {1, 2, 3, 4}, {1, 2, 3, 4}, {1, 2, 3, 4} },
```
```
 { {1, 2, 3, 4}, {1, 2, 3, 4}, {1, 2, 3, 4} } 
```
```
};
```
As you can see, there are two groups, each containing three groups of 4 numbers.

Or

int arr[3][3][3]=
{
{
{11, 12, 13},
{14, 15, 16},
{17, 18, 19}
},
{
{21, 22, 23},
{24, 25, 26},
{27, 28, 29}
},
{
{31, 32, 33},
{34, 35, 36},
{37, 38, 39}
},
};

this is one of the ways
int[,,] array3D = new int[,,] {
                                    //this is first dimention
                                    //[0]
                                    {
                                        //this is second dimention
                                        //[0,0]
                                        {
                                            //this is third dimention
                                            //[0,0,0]
                                            1,
                                            2,
                                            3 },
                                        //[0,1]
                                        { 4, 5, 6 }
                                    },
                                    //[1]
                                    {
                                        { 7, 8, 9 },
                                        { 10, 11, 12 }
                                    }
                                };
But I am just curious, where and how do you plan to use this in work?

Is it an interview question? or a study book question?
