Solution 1

Following is a LinqPad[^] script for demonstration, the bold part is the basic idea you are looking for:

C#

int[,] A = {{1,2},{3,4},{5,6}};
int[,] B ;

B = (int[,])A.Clone();
A[0,0] = 99;

A.Dump();
B.Dump();

You could always try the documentation:

Array.Copy Method (Array, Array, Int32)

C#

int[,] a1 = new int[4, 6];
a1[2, 3] = 4;
a1[3, 5] = 25;
int[,] a2 = new int[a1.GetUpperBound(0) + 1, a1.GetUpperBound(1) + 1];
Array.Copy(a1, a2, a1.Length);
