string content = "木子屋(http://www.mzwu.com/)";
//2字节存储
using (FileStream fs = File.Create(@"c:\test.txt"))

//8字节存储

}若想知道C#将每个字符转成的字节内容，这就需要将short,int,long转成byte[]，使用BitConverter.GetBytes方法可以完成这种转换，代码如下：
byte[] b;
//2字节,0x28 0x67
b = BitConverter.GetBytes((short)'木');
for (int i = 0; i < b.Length; i++)
Console.Write(b[i] + " ");
Console.WriteLine(BitConverter.ToChar(b, 0));
//4字节,0x28 0x67 0 0
b = BitConverter.GetBytes((int)'木');
for (int i = 0; i < b.Length; i++)
Console.Write(b[i] + " ");
Console.WriteLine(BitConverter.ToChar(b, 0));//注意,ToChar只取2个字节进行转换
//8字节,0x28 0x67 0 0 0 0 0 0
b = BitConverter.GetBytes((long)'木');
for (int i = 0; i < b.Length; i++)
Console.Write(b[i] + " ");
Console.WriteLine(BitConverter.ToChar(b, 0));
