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;}}
