C# 客服端上传文件与服务器器端接收 （简单代码）

 简单代码：

    /*服务器端接收写入 可以实现断点续传*/

    public  string  ConnectUpload(string newfilename,string filepath,byte[] fileByte)  

    {

　　  try{

          string path = adpath + newfilename;                     

          FileStream fs = new FileStream(path, FileMode.Append);

          BinaryWriter w = new BinaryWriter(fs);                     

          fs.Position = fs.Length;                     

          fs.Write(fileByte, 0, fileByte.Length);                     

          w.Close();

          fs.Close();

          return "1";

       }

 　    catch{

 　　     return "-1"; 　　

       }

    }



    /*客户端循环添加*/

    int count = 0;

    int bufferSize = 256;        

    byte[] buffer = new byte[bufferSize];

    while (count < FileUpload1.FileContent.Length)        

    {            

        int bytes = FileUpload1.PostedFile.InputStream.Read(buffer, 0, bufferSize);            

        string result = ConnectUpload(newfilename, filepath, buffer);            

        if (result != "1") //报错            

        {　　　　　　　　

             break;

        }　　　　

   }
