WCF Web服务：上载文件，处理该文件，下载已处理的文件 [英] WCF Web Service: Upload a file, Process that file, Download that processed file back

问题描述

我可以处理文件部分的过程，但是在发疯之前，有人构建了一个简单的wcf服务&客户端（可以在Windows Services或IIS下运行）可以用来上传文件，然后下载该文件吗？用最少的代码行？ （C＃或VB）

I can handle the process that file part, but before I go crazy, has someone built a simple wcf service & client (running under windows services or IIS) that I can use to upload a file, and download that file back? with the fewest lines of code? (C# or VB)

压缩和压缩；加密会很酷，但是我稍后再讲！！

compression & encryption would be cool, but i'll layer that on later!!

谢谢！

推荐答案

您应该能够轻松地做到这一点。服务合同可能看起来像这样：

You should be able to do this fairly easily. The service contract would probably look like this:

[ServiceContract]
public interface IFileService
{
  [OperationContract]
  byte[] ProcessFile(byte[] FileData);
}

加密部分可以由WCF使用传输级安全性本地处理。我不相信WCF直接支持压缩，但是您可以使用GZipStream类添加压缩。

The encryption part could be handled natively by WCF using transport level security. I don't believe that WCF supports compression directly, but you could add that using the GZipStream class.

我没有像您描述的那样构建文件处理服务，但是我已经建立了一个服务来处理在WCF客户端和服务之间来回传递的字节数组数据的服务。它工作正常。

I have not built a file handling service as you describe, but I have built a service that handles byte array data that is passed back and forth between a WCF client and service. It works just fine.
