I want to create variable length multi-dimension array at runtime.
Input -> Array that has length of each dimension. Number of dimensions = length of input array.
Output -> variable dimension array.
Example:
Input -> var lengths = new [] {3,4,5}
Expected output -> var arr = new string[3,4,5]
How to do that without and with reflection?
There is this method in the System.Array class :
public static Array CreateInstance(
Type elementType,
int[] lengths
)
See this question for a discussion of GetLength() and GetUpperBound()
But do note that because you don't know the dimensions at compile time you cannot use the familiar a[i,j,k] syntax. All access would look like int[] indices = ...; object x = a.GetValue(indices);
