C＃连接通过代理 [英] C# Connecting Through Proxy

问题描述

我需要通过特定的http代理进行的所有连接一个办公室工作。我需要编写一个简单的应用程序从一个Web服务器查询一些价值观 - 这很容易，如果没有代理。如何让C＃应用程序代理感知？我怎样才能使任何类型的连接通过代理？

I work in a office which requires all connections to be made through a specific http proxy. I need to write a simple application to query some values from a webserver - it's easy if there were no proxy. How can I make the C# application proxy-aware? How can I make any sort of connection through a proxy?

推荐答案

这是很容易要么无论是在web.config中或在app.config实现编程，在code或声明。

This is easily achieved either programmatically, in your code, or declaratively in either the web.config or the app.config.

您可以通过编程创建像这样的代理：

You can programmatically create a proxy like so:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("[ultimate destination of your request]");
WebProxy myproxy = new WebProxy("[your proxy address]", [your proxy port number]);
myproxy.BypassProxyOnLocal = false;
request.Proxy = myproxy;
request.Method = "GET";
HttpWebResponse response = (HttpWebResponse) request.GetResponse();

你基本上分配 WebProxy 对象的要求对象的代理属性。然后，这个要求将使用代理定义。

You're basically assigning the WebProxy object to the request object's proxy property. This request will then use the proxy you define.

要达到同样的事情声明，你可以做到以下几点：

To achieve the same thing declaratively, you can do the following:

<system.net>
  <defaultProxy>
    <proxy
      proxyaddress="http://[your proxy address and port number]"
      bypassonlocal="false"
    />
  </defaultProxy>
</system.net>

你的web.config或app.config中之内。该选项可设置所有HTTP请求将使用默认代理。根据需要实现什么，则可能需要或可能不需要一些 defaultProxy <附加属性/ A> / 代理的元素，因此，请参阅这些文档。

within your web.config or app.config. This sets a default proxy that all http requests will use. Depending upon exactly what you need to achieve, you may or may not require some of the additional attributes of the defaultProxy / proxy element, so please refer to the documentation for those.
