我正在尝试在 asp.net 应用程序中使用关键字查询对象。
我写了这段代码：
命名空间：使用System.Data.SqlClient;
使用 Microsoft.SharePoint；
使用 Microsoft.SharePoint.Search；
使用 Microsoft.SharePoint.Search.Query；
页面加载事件：
GridView grd = new GridView();
DataTable dt = new DataTable();
KeywordQuery qRequest = new KeywordQuery("http://server/ril");
qRequest.QueryText = "RILLIB";
ResultTableCollection resTableCollect = qRequest.Execute();
ResultTable resTable = resTableCollect[ResultType.RelevantResults];
数据表 dtTable = new 数据表();
dtTable.Load(resTable, LoadOption.OverwriteChanges);
grd.DataSource = dtTable;
grd.DataBind();
Page.Controls.Add(grd);
好的？当我运行时，它给了我错误：来自 HRESULT 的异常：0xC0041228
当我看到日志时，我发现了这些行。到底是什么错误？我怎样才能删除它？
