Find the length of only the first dimension in a multi-dimension array

Let's say I have the following: ``` public void MakeMatrix(int matrixLength) { int[,] Matrix = new Matrix[matrixLength,matrixLength] PopulateMatrix(Matrix); PrintMatrix(Matrix); } ``` In the `PrintMatrix(int[,] Matrix)` function, how to I find the length of only one dimension of the multi-dimension array? ``` public void PrintMatrix(int[,] Matrix) { int intLength = // I don't know what to put here <=================== for (int k = 0; k < intLength ; k++) { for (int l = 0; l < intLength; l++) { Console.Write("{0,2} ", Matrix[k, l]); } Console.WriteLine(); } } ```
