Hinweise

If a site-relative URL is passed to the OpenWeb method, the URL is relative to the highest-level Web site that is represented in the URL that is passed to an SPSite constructor. For example, assume that the following sites exist in the SharePoint Foundation deployment:

https://Server/Subsite1/Subsite2
https://Server/sites/SiteCollection/Subsite3

The following table shows the results of passing various URLs to an SPSite constructor and the OpenWeb method.

https://Server/Subsite1/Subsite2/Folder/File	There is no parameter (OpenWeb method overload)	https://Server/Subsite1/Subsite2

Beispiele

The following code example displays the URL for a specified Web site in a console application using a site-relative URL for the OpenWeb method. The example assumes the existence of a Web site located at http://MyServer/MyWebSite/MySubSite.

Dim strUrl As String = "http://MyServer/MyWebSite/Lists/Announcements/AllItems.aspx"

Using oSiteCollection As New SPSite(strUrl)
    Using oWebsite As SPWeb = oSiteCollection.OpenWeb("MyWebSite/MySubSite")
        Console.WriteLine(("Website: " + oWebsite.Url))
    End Using
End Using

string strUrl = "http://MyServer/MyWebSite/Lists/Announcements/AllItems.aspx";

using (SPSite oSiteCollection = new SPSite(strUrl))
{
    using(SPWeb oWebsite = oSiteCollection.OpenWeb("MyWebSite/MySubSite"))
    {
        Console.WriteLine("Website: " + oWebsite.Url);
    }
}
