Resize matrix in c#-CodePudding

I am trying to follow the advices of How to resize multidimensional (2D) array in C#?

However, they do not explain how is the syntax to call the solutions they explained there.

Suppose I have the function,

void ResizeArray<T>(ref T[,] original, int newCoNum, int newRoNum)
        {
            var newArray = new T[newCoNum, newRoNum];
            int columnCount = original.GetLength(1);
            int columnCount2 = newRoNum;
            int columns = original.GetUpperBound(0);
            for (int co = 0; co <= columns; co  )
                Array.Copy(original, co * columnCount, newArray, co * columnCount2, columnCount);
            original = newArray;
        }

and I want to change the size of a double array [,] myMatrix,

How do I call that function, I have been trying,

ResizeArray(myMatrix, 3,3)

but I keep getting errors and I don't understand.

The error says:

Error CS0411: The type arguments for method 'Program.ResizeArray(ref T[,], int, int)' cannot be inferred from the usage. Try specifying the type arguments explicitly. (CS0411)

If I google this error, I don't get any answer for this particular problem. Therefore, I need to ask you. This is all the information I can provide, there is really nothing else. I have a matrix 2x2 and I need to resize it to nxn with a changing n. The solution I found is the one I pasted and the error I get is also pasted.

Hope somebody can help. Regards

You have to specify what T is. Assuming myMatrix contains elements of type double, you need

ResizeArray<double>(myMatrix, 3, 3)
