The most recent question I could find on this is from 2013, so I decided to give it a go.

If my memory serves me right, in Python you can access a ‘slice’ of a multidimensional array like this:

my2dArray[:,0] – will give a 1D array of the first column of the 2D array.

Is there any way to do this in C# at the moment, or is this the only way:

string[] anArray = new string[my2dArray.GetLength(0)];
for(int i = 0; i < my2dArray.GetLength(0); i++) {
    anArray [i] = Convert.ToString(my2dArray[i,0]);
}
