Printing 2D array in matrix format

Question

I have a 2D array as follows:

long[,] arr = new long[4, 4] {{ 0, 0, 0, 0 },
                              { 1, 1, 1, 1 },
                              { 0,          


        

Answer 1

I wrote extension method

public static string ToMatrixString(this T[,] matrix, string delimiter = "\t")
{
    var s = new StringBuilder();

    for (var i = 0; i < matrix.GetLength(0); i++)
    {
        for (var j = 0; j < matrix.GetLength(1); j++)
        {
            s.Append(matrix[i, j]).Append(delimiter);
        }

        s.AppendLine();
    }

    return s.ToString();
}

To use just call the method

results.ToMatrixString();
