How do I delete items in a multidimensional array and will it change the array length?

Question

Say I have a 3d array:

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

How can I delete all items under one of the first dimension? And if that can be done, will that move up all the values under it? Or will the deleted items just take null values and be counted in the arr.GetLength(0) method?

I've found a C# version of the Visual Basic's ReDim method. https://stackoverflow.com/a/327958/9076546 Note that dynamic array sizes aren't the best for performance. ReDim was a mistake in my honest opinion...
