根据条件从DataTable中删除行

Question

我有一个包含一些ID的List.我想从DataTable中删除行= ListLinkedIds

List<string> ListLinkedIds = new List<string>(); //This has values such as 6, 8, etc.
DataSet ds = new DataSet();
SqlDataAdapter da = null;
DataTable dt = new DataTable();



    da = new SqlDataAdapter("SELECT TicketID, DisplayNum, TranstypeDesc, SubQueueId, EstimatedTransTime,LinkedTicketId FROM vwQueueData WHERE (DATEADD(day, DATEDIFF(day, 0, Issued), 0) = DATEADD(day, DATEDIFF(day, 0, GETDATE()), 0)) AND QueueId = @QueueId AND SubQueueId = @SubQueueId   AND LinkedTicketId != @LinkedTicketId  AND Called IS NULL", cs);
   da.SelectCommand.Parameters.AddWithValue("@QueueId", Queue);
   da.SelectCommand.Parameters.AddWithValue("@SubQueueId", SubQueue);
   da.SelectCommand.Parameters.AddWithValue("@LinkedTicketId", ListLinkedIds[x]);
   da.Fill(ds);


//Removes from DataTable 
for (int x = 0; x < ListLinkedIds.Count(); x++)
{
   //Remove Row from DataTable Where ListLinkedIds[x]
}


gvMain.DataSource = ds;
gvMain.DataBind();

我尝试了dt.Rows.RemoveAt(删除),但只删除了行号.我想删除ListLinkedIds中的每一行.

使用LINQ,您可以创建一个新的DataTable:

DataTable newDataTable = dt.AsEnumerable()
                        .Where(r=> !ListLinkedIds.Contains(r.Field<string>("IDCOLUMN")))
                        .CopyToDataTable();
