如何将列数据绑定到数据源？

I got table with 1 row and 3 columns(date,time,what), I want 2 of the 3 columns(time,what) in my datasource how can i do that?

我得到的表有1行3列（日期，时间，什么），我想在我的数据源中的3列中的2列（时间，什么），我该怎么做？

var table = (from r in socialEvents.AsEnumerable()
                         where r.Field<DateTime>("Date") >= Calendar1.SelectedDate.Date &&
                               r.Field<DateTime>("Date") <= Calendar1.SelectedDate.AddDays(1)
                         select r).CopyToDataTable();    

    if (table.Rows.Count > 0)
                {
                    DataGrid1.Visible = true;
                    DataGrid1.DataSource = table;
                    DataGrid1.DataBind();
                }

2 个解决方案

#1

I'm assuming that datagrid is a GridView? then you should be to do something like this

我假设datagrid是GridView？那么你应该做这样的事情

<asp:GridView runat="server" AutoGenerateColumns="false"  >
<Columns>
    <asp:BoundField DataField="what" HeaderText="what" />
    <asp:BoundField DataField="time" HeaderText="time"  />        
</Columns>

</asp:GridView>

#2

you can specify the columns in the select

您可以在select中指定列

var table = (from r in socialEvents.AsEnumerable()
                         where r.Field<DateTime>("Date") >= Calendar1.SelectedDate.Date &&
                               r.Field<DateTime>("Date") <= Calendar1.SelectedDate.AddDays(1)
                         select new {time = r.Field<DateTime>("Date"), what = r.Field<data_type>("what") });
