您应该能够从您的查询直接绑定到您的网格：

you should be able to bind to your grid straight from your query:

`变种的用户= eFactory.SYMPOSIUM_Users.Where（A => a.UserID == eval.UserID.Value＆放大器;＆安培; a.Active.Value和放大器;＆安培; a.UserRole == 1）;
this.mygrid.DataSource =用户;

`var users = eFactory.SYMPOSIUM_Users.Where(a => a.UserID == eval.UserID.Value && a.Active.Value && a.UserRole == 1); this.mygrid.DataSource = users;

我会建议采取一看 asp.net网站网站的教程。很多很好的内容在那里。

I would suggest taking a look at the asp.net web site for tutorials. Lots of good content out there.

更新：结果
也许你的***的办法就是在你的两个表创建一个加入一个匿名类型，这样您不必重复查询您的数据存储和数据绑定你会简单一些。

Update:
Perhaps your best solution is to create an anonymous type from a join on your two tables, this way your not repeatedly querying your data store, and your databinding will be simpler.

var result = (from i in eFactory.Symposium_Evaluation
              join user in eFactory.SYMPOSIUM_Users on i.UserID equals user.UserID
              where user.UserRole == 1 &&
                   ((!i.Completed.HasValue || 
                     i.Completed.Value == 0) && 
                    i.Active && a.UserID >= 2063)
              select new {
                  User = user,
                  Symposium = i
              }).ToList();

myDataGrid.DataSource = result;
myDataGrid.DataBind();

现在网格中的行模板，您可以：

Now in your grid row template you can:

<%#Eval("User.FirstName")%>
<%#Eval("User.LastName")%>
<%#Eval("User.Email")%>
