Examples

下列程式碼範例會逐一查看所有使用者的指定的網站集合中每個網站，並顯示網站集合管理員網站群組的成員使用者的使用者名稱。

這個範例需要Microsoft.SharePoint和Microsoft.SharePoint.Utilities命名空間using指示詞 (在 Visual Basic 中的Imports )。

Dim siteCollection As SPSite = SPContext.Current.Site
Dim webSites As SPWebCollection = siteCollection.AllWebs("Site_Name").Webs
Dim i As Integer

For i = 0 To webSites.Count - 1

    Dim users As SPUserCollection = webSites(i).Users
    Dim j As Integer

    For j = 0 To users.Count - 1

        If users(j).IsSiteAdmin Then

            Response.Write(SPEncode.HtmlEncode(webSites(i).Title) & " :: " 
                & users(j).LoginName & "<BR>")

        End If

    Next j

    collWebsites(intIndexWebsites).Dispose()
Next i

SPSite oSiteCollection = SPContext.Current.Site;
SPWebCollection collWebsites = oSiteCollection.AllWebs["Website_Name"].Webs;

for (int intIndexWebsites = 0; intIndexWebsites < collWebsites.Count; 
     intIndexWebsites++)
{
    SPUserCollection collUsers = collWebsites[intIndexWebsites].Users;
    for (int intIndexAdmins = 0; intIndexAdmins < collUsers.Count; 
         intIndexAdmins++)
    {
        if (collUsers[intIndexAdmins].IsSiteAdmin)
        {
            Response.Write(SPEncode.HtmlEncode(collWebsites[intIndexWebsites].Title) 
              + "--" + collUsers[intIndexAdmins].LoginName + "<BR>");
        }
    }
    collWebsites[intIndexWebsites].Dispose();
}

Certain objects implement the IDisposable interface, and you must avoid retaining these objects in memory after they are no longer needed. For information about good coding practices, see Disposing Objects.
