Question

I have a text file that has the following in it: (Without quotation marks and “Empty Space”)

• ##############
• # Empty Space#
• # Empty Space#
• # Empty Space#
• # Empty Space#
• ##############

I want to add this whole file row by row into a list:

FileStream FS = new FileStream(@"FilePath",FileMode.Open);
StreamReader SR = new StreamReader(FS);
List<string> MapLine = new List<string>();

foreach (var s in SR.ReadLine())
{
    MapLine.Add(s.ToString());                   
}

foreach (var x in MapLine)
{
    Console.Write(x);
}

Here comes my problem: I want to add this into a Two dimensional array. I tried:

string[,] TwoDimentionalArray = new string[100, 100];

for (int i = 0; i < MapLine.Count; i++)
{
    for (int j = 0; j < MapLine.Count; j++)
    {
        TwoDimentionalArray[j, i] = MapLine[j].Split('\n').ToString();
    }
}

I am still new to C# so please any help will be appreciated.

You can try with this:

        // File.ReadAllLines method serves exactly the purpose you need
        List<string> lines = File.ReadAllLines(@"Data.txt").ToList();

        // lines.Max(line => line.Length) is used to find out the length of the longest line read from the file
        string[,] twoDim = new string[lines.Count, lines.Max(line => line.Length)];

        for(int lineIndex = 0; lineIndex < lines.Count; lineIndex++)
            for(int charIndex = 0; charIndex < lines[lineIndex].Length; charIndex++)
                twoDim[lineIndex,charIndex] = lines[lineIndex][charIndex].ToString();

        for (int lineIndex = 0; lineIndex < lines.Count; lineIndex++)
        {
            for (int charIndex = 0; charIndex < lines[lineIndex].Length; charIndex++)
                Console.Write(twoDim[lineIndex, charIndex]);

            Console.WriteLine();
        }

        Console.ReadKey();

This is going to save each character of the file content into it’s own position in a 2-dimensional array. For that purpose char[,] might have also been used.
