c#中文件流的读写

  

文件流读入：第一
static void Main(string[] args)
        {
            //C#文件流写文件,默认追加FileMode.Append 
            string msg = "okffffffffffffffff";
            byte[] myByte = System.Text.Encoding.UTF8.GetBytes(msg);  //转换为字节
            using (FileStream fsWrite = new FileStream(@"D:1.txt", FileMode.Append))
            {
                fsWrite.Write(myByte, 0, myByte.Length);
            }; 
            //c#文件流读文件 
            using (FileStream fsRead = new FileStream(@"D:1.txt", FileMode.Open))
            {
                int fsLen = (int)fsRead.Length;
                byte[] heByte = new byte[fsLen];
                int r = fsRead.Read(heByte, 0, heByte.Length);
                string myStr = System.Text.Encoding.UTF8.GetString(heByte);
                Console.WriteLine(myStr);
                Console.ReadKey();
            } 
        }

第二种方式

 static void Main(string[] args)
        {
            String name = "张雨";
            FileStream file = new FileStream("e:\zhang.txt",FileMode.Create);

            StreamWriter write = new StreamWriter(file);

            write.Write(name);


            write.Close();

            file.Close();

            Console.WriteLine("写入成功");


            Console.ReadKey();

        }
