正在停用SharePoint中的Web部件功能

这是预期行为。您可以自动删除它,但您必须编写一个功能接收器来完成这一点。

有关为SharePoint 2007创建功能接收器的详细信息: http://sharepointdevwiki.com/display/public/How+to+add+a+Feature+Receiver+to+a+Feature

创建Web部件时,wspbuilder会自动将删除事件接收器添加到功能中。非常方便。

您可以使用以下代码来完成此操作:

public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
{
    SPSite site = properties.Feature.Parent as SPSite;

    if (site != null)
    {
        try
        {
            SPList wpGallery = site.GetCatalog(SPListTemplateType.WebPartCatalog);
            SPQuery query = new SPQuery();
            query.Query = “<Where><Eq><FieldRef Name=’FileLeafRef’ /><Value Type=’Text’>webpartname.webpart</Value></Eq></Where>”;
            SPListItemCollection items = wpGallery.GetItems(query);

            if (items.Count > 0)
            {
                items[0].Delete();
            }
        }
        catch { }
    }
}
