绑定多个字段在ASP.NET列表框

问题描述：

我是相当新的asp.net，尤其是LINQ和SQL。

I'm fairly new to asp.net and especially LINQ and SQL.

说我有一个表员工有田姓氏，名字和ID。

Say I have a table "Employees" with fields "Lastname", "Firstname", and "ID".

我想这个绑定到一个列表框。我想在列表框中显示它的内容，如$ LASTNAME，$名字，我想每个项目的价值是ID。

I want to bind this to a list box. I want the list box to display it's contents like "$LASTNAME, $FIRSTNAME" and I want the value of each item to be "ID".

这是微不足道的绑定或者名字列到列表框中，并相应的值，但我无法弄清楚如何做到这一点..

It's trivial to bind either name column to the listbox and the values accordingly, but I can't figure out how to do this..

在此先感谢

您可以尝试这样的事：

var datasource = from employee in employees 
                 select new
                 { 
                     Name = employee.lastName + ", " + employee.firstName, 
                     Id = employee.ID 
                 };

myListBox.DataSource = datasource;
myListBox.DataTextField = "Name";
myListBox.DataValueField = "Id";
myListBox.DataBind();

此构造匿名类型的列表，你的员工表到你的列表框绑定。

This constructs a list of anonymous types from your employee table to bind your listbox to.
