linq to sql只显示datagrid中三列中的两列

Question

我是新来的linq to sql。我可以做一些原始查询。

我有一个领域[TotalID] INT表TotalDoc，[TotalDate] datetime和[总金额]浮动

var items = from i in v.db.TotalDoc 
      orderby i.TotalID descending 
      select i; 

dataGridView.DataSource = items; 

如何构建一个查询，将返回唯一ID和日期字段？

Answer 1

var items = (from i in v.db.TotalDoc 
      orderby i.TotalID descending 
      select new {i.TotalID, i.Date}).ToList(); 

Answer 2

可以初始化新地产这样

var items = (from i in db.TotalDoc 
      order by i.TotalID descending 
      select new { ID = i.TotalID, NewDate = i.Date}).ToList();
