enter image description here我對分組和suming列此代碼：Linq的分組和數據表塞汀
var groupedData = from b in showit.AsEnumerable()
group b by b.Field<string>("Key") into g
select new
{
KeyName = g.Key,
Calls_Chats_Answered = g.Sum(x => x.Field<int>("Calls_Chats_Answered"))
};
如何通過groupedData到數據表？
//Create DataTable
DataTable dt = new DataTable();
//Add DataColumns to DataTable
dt.Columns.Add("KeyName", typeof(string));
dt.Columns.Add("Calls_Chats_Answered", typeof(int));
//Iterate over the query
foreach (var v in groupedData)
{
//Create new DataRow
DataRow dr = dt.NewRow();
//Add values to DataRow
dr["KeyName"] = v.KeyName;
dr["Calls_Chats_Answered"] = v.Calls_Chats_Answered;
//Add DataRow to DataTable
dt.Rows.Add(dr);
}

應該在哪裏顯示分組數據？圖像沒有更清晰。 –
