WPF 使用LINQ 检索结果作为Binding源

通过LINQ我们可以方便的操作集合对象、DataTable对象而不必动辄就把好几层foreach循环嵌套在一起只是为了完成一个很简单的任务。

集合类

class Student    {        public int Id { get; set; }        public string Name { get; set; }        public int Age { get; set; }    }

界面代码，设定一个数据表格安装数据

<StackPanel Background="LightBlue">        <ListView x:Name="listViewStudents" Height="143" Margin="5">            <ListView.View>                <GridView>                    <GridViewColumn Header="Id" Width="60" DisplayMemberBinding="{Binding Id}"/>                    <GridViewColumn Header="Name" Width="100" DisplayMemberBinding="{Binding Name}"/>                    <GridViewColumn Header="Age" Width="80" DisplayMemberBinding="{Binding Age}"/>                </GridView>            </ListView.View>        </ListView>        <Button Content=" Load" Height="25" Margin="5,0" Click="Button_Click"/>    </StackPanel>

后台代码

 private void Button_Click(object sender, RoutedEventArgs e)        {            List<Student> stuList = new List<Student>();            {                stuList.Add(new Student() { Id = 1, Name = "Tim", Age = 29 });                stuList.Add(new Student() { Id = 1, Name = "Tom", Age = 28 });                stuList.Add(new Student() { Id = 2, Name = "Kyle", Age = 27 });                stuList.Add(new Student() { Id = 3, Name = "Tony", Age = 26 });                stuList.Add(new Student() { Id = 4, Name = "Vina", Age = 25 });                stuList.Add(new Student() { Id = 5, Name = "Mike", Age = 24 });            };            this.listViewStudents.ItemsSource = from stu in stuList where stu.Name.StartsWith("T") select stu;                   }

最后，调用的结果如下
