DataGridView显示类型而不是值

Question

我有一个带有DataGridView的WinForms表单。 DataGridView是从LINQ to SQL查询填充的，如下所示。当我运行代码时，gridview似乎显示列值而不是实际值。

DataGridView没有设计时源，并且列的DataPropertyName等于数据库中的列。

我错过了什么，它没有显示实际值？

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

问题在于选择

 select new { DateSent, DateReceived, ReceivedFrom})

应该是

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

您正在选择列而不是值
