C#实现的基于二进制读写文件操作示例

using System;
using System.IO;
class MyStream 
{
  private const string FILE_NAME = "Test.data";
  public static void Main(String[] args) 
  {
    // Create the new, empty data file.
    if (File.Exists(FILE_NAME)) 
    {
      Console.WriteLine("{0} already exists!", FILE_NAME);
      return;
    }
    FileStream fs = new FileStream(FILE_NAME, FileMode.CreateNew);
    // Create the writer for data.
    BinaryWriter w = new BinaryWriter(fs);
    // Write data to Test.data.
    for (int i = 0; i < 11; i++) 
    {
      w.Write( (int) i);
    }
    w.Close();
    fs.Close();
    // Create the reader for data.
    fs = new FileStream(FILE_NAME, FileMode.Open, FileAccess.Read);
    BinaryReader r = new BinaryReader(fs);
    // Read data from Test.data.
    for (int i = 0; i < 11; i++) 
    {
      Console.WriteLine(r.ReadInt32());
    }
    w.Close();
  }
}
