In .net, I need to securely transfer files 4mb in size from client machines running my software to a central server, process, and securely send back results consisting of a pdf file, a jpg image, and xml data. 在.net中，我需要从运行我的软件的客户端计算机安全地将大小为4mb的文件传输到中央服务器，进行处理，并安全地发送包含pdf文件，jpg图像和xml数据的结果。

What .net technology would be most appropriate for this? 哪种.net技术最适合于此？ (web service. remoting, etc) （网络服务，远程处理等）

1 个解决方案

WCF- If it is .NET to .NET (like it sounds like it is), then you should use WCF with TCPBinding. WCF-如果从.NET到.NET（听起来像是这样），则应将WCF与TCPBinding一起使用。 There are lots of good examples here to get you started. 这里有很多很好的例子，可以帮助您入门。 You might want to consider streaming if scalability is a concern. 如果要考虑可伸缩性，则可能要考虑流式传输。

If you want to host in IIS (then you can't use TCP- but consider WAS), make sure you use MTOM . 如果要在IIS中托管（那么您就不能使用TCP-，而是考虑使用WAS），请确保使用MTOM 。 If you're still unsure as to which binding to use, then have a look at this binding decision diagram . 如果您仍然不确定要使用哪种绑定，请查看此绑定决策图。

WCF has a lots of security options for you to consider. WCF有很多安全选项供您考虑。 You will find the Patterns and Practises- WCF Security Guidance useful for this. 您会发现“ 模式和实践-WCF安全指南 ”对此很有用。

Please note that ASMX Webservices and remoting are now considered legacy- WCF is the way forward. 请注意，ASMX Web服务和远程处理现在被认为是旧式-WCF是前进的方向。

Update- If your operating system supports it, then you may wish to consider using WAS . 更新-如果您的操作系统支持它，那么您不妨考虑使用WAS 。
