While I don't have specific experience with Windows Mobile this error message generally indicates a failure to resolve a hostname to an IP address. This can happen for a number of reasins including:
虽然我没有使用 Windows Mobile 的具体经验，但此错误消息通常表示无法将主机名解析为 IP 地址。发生这种情况的原因有很多，包括：
- The client can not contact the DNS server to attempt to resolve the name. This suggests a lack of network and/or internet connectivity
- The DNS query did not yeild a result.
- 客户端无法联系 DNS 服务器以尝试解析名称。这表明缺乏网络和/或互联网连接
- DNS 查询没有产生结果。
Resolution Suggestions:
解决建议：
- Check that the name is correctly specified
- Verify that there is network connectivity as this is required to communicate with the DNS server(s) used to resolve a hostname
- Check that the DNS server address is correct especially if they are configured staticlly.
- 检查名称是否正确指定
- 验证是否存在网络连接，因为这是与用于解析主机名的 DNS 服务器通信所必需的
- 检查 DNS 服务器地址是否正确，特别是如果它们是静态配置的。
Hope this helps

This means that while processing the URL for the web server, the underlying network connection was unable to convert the name into an IP address. The two most likely reasons this could be happening are
这意味着在处理 Web 服务器的 URL 时，底层网络连接无法将名称转换为 IP 地址。发生这种情况的两个最可能的原因是
- You introduced a typo into the URL you put into the application
- You are currently experiencing a DNS issue on your network
- 您在输入应用程序的 URL 中引入了拼写错误
- 您目前在网络上遇到 DNS 问题
The quickest way to verify this is to try and pull up the web site in the mobile browser. If you can't pull it up it's likely a DNS issue.
验证这一点的最快方法是尝试在移动浏览器中打开网站。如果您无法将其拉起，则可能是 DNS 问题。

My number one suggestion to you is to try it in the browser on the device. If it works on the browser then it should work in your code. If it doesn't then it's a setup issue on your device OR if you are connected by ActiveSync, it may be a network issue on your host machine (like a firewall).
我给您的第一个建议是在设备上的浏览器中尝试。如果它适用于浏览器，那么它应该适用于您的代码。如果不是，则是您设备上的设置问题，或者如果您通过 ActiveSync 连接，则可能是主机上的网络问题（如防火墙）。
Also note that your code will NOT automatically create a cellular network connection. You are to the Connection Managerto requestit before doing your web requests.
