设置WebClient请求的User-Agent标头 [英] Setting the User-Agent header for a WebClient request

问题描述

为Windows Phone 7的WebClient请求设置User-Agent标头的正确方法是什么？
我找到了2个选项，但是不确定哪个是正确的。考虑一个WebClient对象：

What is the proper way of setting the User-Agent header for a WebClient request for Windows Phone 7? I found 2 options, but not sure which one is the correct one. Considering a WebClient object:

WebClient client = new WebClient();

我看到了2种选择：

1. 使用以下方法设置用户代理：

1. set the User-Agent using:

client.Headers["User-Agent"] = "myUserAgentString";

使用WebHeaderCollection设置用户代理：

set the User-Agent using the WebHeaderCollection:

WebHeaderCollection headers = new WebHeaderCollection();
headers[HttpRequestHeader.UserAgent] = "userAgentString";
client.Headers = headers;

能否请您告知两种方法中的哪一种

Can you please advise which of the 2 methods above is the proper one?

推荐答案

您可以检查 WebClient 文档，以获取向其中添加用户代理的C＃示例您的 WebClient 和此处是Windows Phone的示例。

You can check the WebClient documentation for a C# sample that adds a User-Agent to your WebClient and here for a sample for Windows Phone.

这是C＃的示例：

WebClient client = new WebClient ();

// Add a user agent header in case the 
// requested URI contains a query.

client.Headers.Add ("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; " + 
                                  "Windows NT 5.2; .NET CLR 1.0.3705;)");

这是Windows Phone（Silverlight）的示例：

This is a sample for Windows Phone (Silverlight):

request.Headers["UserAgent"] = "appname";
// OR
request.UserAgent = "appname";
