Copy one 2D array to another 2D array

arrays, c#, multidimensional-array

Solution

This is correct: `Array.Copy` performs a shallow copy, so the instances of arrays inside the inner dimension get copied by reference. You can use LINQ to make a copy, like this:

var copy2d = orig2d.Select(a => a.ToArray()).ToArray();

Here is a demo on ideone.

Problem

I used this code to copy one 2D array to another 2D array: ``` Array.Copy(teamPerformance, 0,tempPerformance,0, teamPerformance.Length); ``` However, when I change some data in `tempPerformance` then these changes also apply to `teamPerformance`. What should I do to control that?
