DataGridView顯示類型而不是值

Question

我有一個WinForms格式的DataGridView。 DataGridView從LINQ填充到SQL查詢如下。當我運行代碼時，gridview似乎顯示列值而不是實際值。

DataGridView沒有設計時間源，並且這些列的DataPropertyName等於數據庫中的列。

我錯過了什麼，它不顯示實際值？

var q = (from r in db.MessagesReceived 
     orderby r.ID descending 
     select new { DateSent, DateReceived, ReceivedFrom}).Take(TopNumber); 


//dgv.AutoGenerateColumns = false; 
dgv.DataSource = q; 
dgv.Refresh(); 

Answer 1

問題是在選擇

select new { DateSent, DateReceived, ReceivedFrom}) 

應該

select new { DateSent=r.DateSent, DateReceived=r.DateReceived, ReceivedFrom=r.ReceivedFrom}) 

您選擇的列，而不是值
