'用途
Dim instance As SPSiteCollection

public class SPSiteCollection : SPBaseCollection, 
    IEnumerable<SPSite>, ICollection, IEnumerable

備註

使用SPWebApplication類別之Sites屬性可傳回代表 Web 應用程式的所有網站集合的SPSite物件的集合。若要建立網站集合，請使用Add方法。

若要從集合中傳回單一站台物件使用索引器。例如，若集合已指派給變數mySites，使用mySites[index]以 C# 或 Visual Basic，其中index是集合中網站物件的索引編號，或是站台的顯示名稱中的mySites(index) 。

Examples

下列範例會逐一查看目前的 Web 應用程式的每個已新增至群組的成員，將項目新增至最上層的宣告清單內的所有網站集合。

Dim webApp As SPWebApplication = SPContext.Current.Site.WebApplication
Dim siteCollections As SPSiteCollection = webApp.Sites

Dim siteCollection As SPSite

For Each siteCollection In  siteCollections
    Dim changes As SPChangeCollection = siteCollection.GetChanges()
    Dim change As SPChange

    For Each change In  changes
        If change.ChangeType = SPChangeType.MemberAdd Then
            Dim webSite As SPWeb = siteCollection.OpenWeb()
            Dim groups As SPGroupCollection = webSite.Groups
            Dim list As SPList = webSite.GetList("Lists/Announcements")
            Dim items As SPListItemCollection = list.Items
            Dim group As SPChangeGroup = CType(change, SPChangeGroup)

            Dim item As SPListItem = items.Add()
            item("Title") = "User added to " + 
                groups.GetByID(group.Id).Name + " on " + 
                change.Time.ToString()
            item.Update()
        End If
    Next change
Next siteCollection

SPWebApplication webApp = SPContext.Current.Site.WebApplication;
SPSiteCollection siteCollections = webApp.Sites;

foreach (SPSite siteCollection in siteCollections)
{
    SPChangeCollection changes = siteCollection.GetChanges();

    foreach (SPChange change in changes)
    {
        if (change.ChangeType == SPChangeType.MemberAdd)
        {
            SPWeb webSite = siteCollection.OpenWeb();
            SPGroupCollection groups = webSite.Groups;
            SPList list = webSite.GetList("Lists/Announcements");
            SPListItemCollection items = list.Items;

            SPChangeGroup group = (SPChangeGroup)change;

            SPListItem item = items.Add();
                    item["Title"] = "User added to " + 
                    groups.GetByID(group.Id).Name + " on " +
                     change.Time.ToString();
            item.Update();
        }
    }
}
