C#中如何从一个文本文件读取数字储存到一个byte数组里面

[lx2222]

我一个文本文档中有N个二维数组，byte型的中间用#######################分割 数字用空格分隔
我想一次读取一个，放进一个byte[,]数组里面，大小是固定的[15,15]，下次在读取下一个 求教各位该怎么办
例如
0 0 0 0 0 0 0 6 0 0 0 0 0 0 0
0 0 0 0 0 0 6 0 0 0 0 4 0 0 0
0 0 0 5 0 0 0 0 0 0 0 4 0 0 0
0 0 0 1 6 1 1 1 6 1 1 1 1 0 0
0 0 0 1 0 0 0 0 2 2 2 2 1 0 0

谢谢楼上几位的回答，三楼朋友的代码考虑的很全面谢谢

小弟还有个问题，就是假如我文本里面的数组很多我想一个一个读取，而不是一下子读到内存里面来，该怎么办可不可以每次读取某几行，这个函数该怎么用？
谢谢各位前辈了

private void button2_Click(object sender, EventArgs e)
        {
            FileStream fs = new FileStream("test.txt", FileMode.Open);
            int index = 7;//取第几行数据,从0开始,此处可由用户输入
            const int length = 32;//每行的长度,15个字符+15个空格+回车换行2=32
            byte[] buff = new byte[length];
            long line = index * length;//计算第index行前面占用的字节数
            fs.Seek(line, SeekOrigin.Begin);//移动文件流指针位置
            fs.Read(buff, 0, length);//从指定位置读取指定长度字节赋值给buff
            fs.Close();
            
            for (int i = 0; i < buff.Length; i+=2)//i++保留空格,i+=2去掉空格
            {
                Console.Write((char)buff[i]);//输出结果符合要求,buff就是要的结果
            }
            
        }

另外,如果第N行内容是"############",则不是所需要的,可加个判断直接return

[peter20091001]

文本文件应该用文本模式读写,用StreamReader/StreamWriter
如果文件中不只包含文本,应该用二进制模式读写,BinaryReader/BinaryWriter
