如何从linq的结果中选择值 [英] How to select the values from the Result of linq

问题描述

我有一个gridview，因为我有选中复选框。在选择行并单击更新按钮时，我选择通过linq在gridview中选择的行。在这个选定的linq查询中，我想得到两个列值（SlNO，RefNO）作为结果集。如何通过linq获得这个。这是我从网格中选择所选值的linq代码。

 var result =  from  GridViewRow msgRow  in  grdPrice.Rows 
  where （（CheckBox）msgRow .FindControl（  chkSelect））。选中
 选择 grdPrice.Rows [msgRow.RowIndex]; 

谢谢

解决方案

您可以使用匿名类型属性来完成任务。请检查以下示例。

  var  result =（ from  GridViewRow msgRow < span class =code-keyword> in  grdPrice.Rows 
  where （（CheckBox）msgRow.FindContr ol（  chkSelect））。选中
 选择  new  {
 SlNO = YourSInoValue，
 RefNO = YourRefNOValue，
}。）ToList（）; 

Hi,

I am having a gridview in that I am having select check box. While selecting the rows and clicking the Update button I am selecting the rows which are selected in the gridview through linq. In this selected linq query I want to get the two column values(SlNO,RefNO) as a result set. How to get this one through linq. Here is my linq code for selecting the selected value from the grid.

var result = from GridViewRow msgRow in grdPrice.Rows
                    where ((CheckBox)msgRow.FindControl("chkSelect")).Checked
                    select grdPrice.Rows[msgRow.RowIndex];
