xxx不是有效的虚拟路径？

Question

我用XmlDataSource这样的:

<asp:XmlDataSource ID="xmlDataSource1" runat="Server" DataFile="https://myurl.xml" ></asp:XmlDataSource>

作为我rotater控制的数据源.

但我一直得到以下例外:

https://myurl.xml不是有效的虚拟路径.

虽然我在外部尝试了链接,但是有一个xml文件

忽略我之前的回答.显然,XmlDataSource不喜欢https网址DataFile:

// works
xmlDataSource1.DataFile = "http://code.google.com/feeds/p/google-code-prettify/svnchanges/basic";
// does not work
xmlDataSource1.DataFile = "https://code.google.com/feeds/p/google-code-prettify/svnchanges/basic";

写一些额外的代码行来从https源下载XML,如:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://code.google.com/feeds/p/google-code-prettify/svnchanges/basic");
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream()); 
string str = reader.ReadToEnd();
// save it or set it as the .Data property of XmlDataSource
