文件流的读取
//使用FileStream来读取数据FileStream fsRead = new FileStream(@"C:\Users\SpringRain\Desktop\new.txt", FileMode.OpenOrCreate, FileAccess.Read);byte[] buffer = new byte[1024 * 1024 * 5];//3.8M 5M//返回本次实际读取到的有效字节数int r = fsRead.Read(buffer, 0, buffer.Length);//将字节数组中每一个元素按照指定的编码格式解码成字符串string s = Encoding.UTF8.GetString(buffer, 0, r);//关闭流fsRead.Close();//释放流所占用的资源fsRead.Dispose();Console.WriteLine(s);Console.ReadKey();
文件流的写入
//使用FileStream来写入数据using (FileStream fsWrite = new FileStream(@"C:\Users\SpringRain\Desktop\new.txt", FileMode.OpenOrCreate, FileAccess.Write)){string str = "看我游牧又把你覆盖掉";byte[] buffer = Encoding.UTF8.GetBytes(str);fsWrite.Write(buffer, 0, buffer.Length);}Console.WriteLine("写入OK");Console.ReadKey();
