C# - implementing Copying 2D Array Elements and advanced patterns in Loop
Could someone explain I'm working with an unexpected behavior when trying to copy elements from one 2D array to another in C#... I'm using a nested loop to copy the values, but after copying, the second array seems to hold reference types rather than distinct values. This leads to changes in one array also affecting the other, which is not what I intended. Here’s a simplified version of what I have: ```csharp int[,] sourceArray = new int[3, 3] { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } }; int[,] destinationArray = new int[3, 3]; for (int i = 0; i < sourceArray.GetLength(0); i++) { for (int j = 0; j < sourceArray.GetLength(1); j++) { destinationArray[i, j] = sourceArray[i, j]; } } sourceArray[0, 0] = 10; // Check the destination array Console.WriteLine(destinationArray[0, 0]); // Output should be 1 ``` I expected `destinationArray[0, 0]` to still be `1` after changing `sourceArray[0, 0]` to `10`, but it seems to reflect changes from the `sourceArray`. I've double-checked the array size and the indexing, and everything appears to be correct. I also tried reinitializing the `destinationArray`, but the same question continues. Is there something subtle I might be missing when dealing with 2D arrays in C#? Any insights into this behavior would be greatly appreciated! The stack includes C# and several other technologies.
