            String [,] array2D;
            int numberOfLines = 0, numberOfColumns = 0;
            string line;
            String filename = "C:\\Decomposition\\Analyse\\image143\\feature143.txt";
            System.IO.StreamReader sr = new System.IO.StreamReader(filename);

You can pass multiple delimiters to the split method.

i.e
numberOfColumns = line.Split(new char[] { '\t', ' ' }, StringSplitOptions.RemoveEmptyEntries).Length;
