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:

我看到了 2 个选项:

I saw 2 options:

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;

你能告诉我上面两种方法中哪一种是正确的吗?

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

推荐答案

您可以查看WebClient 文档，用于将用户代理添加到您的 WebClient 和 此处获取 Windows Phone 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";
