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;
        }　　　　
   }
