"Index was outside the bounds of the array."

I'm trying to read a text file and store it into an array, then draw a map according to the contents of the file. The file contents are:

2000002

2111112

2222222

I'm using this code to read the file, then draw it:

1	public void InitializeReadMaps(int map) // this is just run once, it's just a test
2	{
3	this.FileName = "map" + map.ToString() + ".txt";
4	this.file = new FileStream(this.FileName, FileMode.Open, FileAccess.Read);
5	this.sr = new StreamReader(this.file);
6	string line = this.sr.ReadLine();
7	this.YLength = Int32.Parse(line);
8	this.XLength = Int32.Parse(line);
9	this.map = new char[this.XLength, this.YLength];
10	}
11
12	public void ReadMaps()
13	{
14	if (!sr.EndOfStream)
15	{
16	for (int y = 0; y < (this.YLength - 1); y++)
17	{
18	string line = this.sr.ReadLine();
19	for (int x = 0; x < (this.XLength - 1); x++)
20	{
21	map[x, y] = line[x];
22	}
23	}
24	}
25	}
26
27	public void DrawContent(SpriteBatch spriteBatch)
28	{
29	for(int y = 0; y < this.YLength; y++)
30	{
31	for (int x = 0; x < this.XLength; x++)
32	{
33	switch (this.map[x,y])
34	{
35	case '1': tile.DrawTile(spriteBatch, x, y, 1); break;
36	case '2': tile.DrawTile(spriteBatch, x, y, 2); break;
37	}
38	}
39	}
40	}
