当尝试使用SPWeb.GetSiteData(SPSiteDataQuery)
(尝试将某些数据绑定到SPGridView)时,它会抛出一个带有以下堆栈跟踪的TargetInvocationException:
at System.RuntimeMethodHandle._InvokeMethodFast(Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner)
at System.RuntimeMethodHandle.InvokeMethodFast(Object target, Object[] arguments, Signature sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner)
at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks)

at System.Web.UI.WebControls.BaseDataBoundControl.DataBind()
at System.Web.UI.WebControls.GridView.DataBind()
at Balticovo.SharePoint.WebParts.CrossSiteDataQueryWebPart.OnLoad(EventArgs e)
正在调用的方法是GetData。在使用消息Exception from HRESULT: 0x80020009 (DISP_E_EXCEPTION))
调查InnerException之后,看起来SharePoint想要释放资源:
at Microsoft.SharePoint.Library.SPRequest.ReleaseResources()
at Microsoft.SharePoint.SPRequestManager.Release(SPRequest request)
at Microsoft.SharePoint.SPWeb.Invalidate()
at Microsoft.SharePoint.SPWeb.Close()
at Microsoft.SharePoint.SPWeb.Dispose()
at Balticovo.SharePoint.Extensions.GetCrossSiteData(SPWebApplication webApp, SPCrossSiteDataQuery query)
at Balticovo.SharePoint.TasksTableAdapter.GetData(Guid queryId, Boolean dataForOutlook)
at Balticovo.SharePoint.TasksTableAdapter.GetData(Guid queryId)
但所有这些方法直到SPWeb.Dispose()我都没有在调用SPWeb.GetSiteData(SPSiteDataQuery)之前处置任何内容,然后抛出异常。
SPWebApplication的实例我是这样的 - Microsoft.SharePoint.WebControls.SPControl.GetContextWebApplication(HttpContext.Current);
然后我在函数GetCrossSiteData中执行这样的操作:
foreach (string siteUrl in query.QuerySites)
{
try
{
using (SPSite site = new SPSite(siteUrl))
using (SPWeb web = site.OpenWeb())
{
DataTable dt = web.GetSiteData(query.SiteDataQuery); //Hangs here
....
}
}
}
有什么想法吗?谢谢。
答案 0 :(得分:0)
事实证明原因是,对于某些列表,TemplateFeatureId属性设置为一个实际上不存在或以某种方式更改的模板。在我的情况下,我只是重新创建了这些列表,现在查询运行正常。
通过这篇文章找到了这个:http://blog.myitechnology.com/2009/06/fixing-feature-guid-for-list-template.html
只是不要使用该工具来解决问题 - 他说他正在修改内容数据库(我想直接)。那是不禁的。我只是用它来查看哪些列表有问题。
