Silverlight DataGrid DateTime StringFormat 日期时间格式

Silverlight Dategrid绑定日期时间格式常常困扰本人，记性又不好，特记示例如下备忘：

1、xaml前台绑定

        <Grid  > 

            <sdk:DataGrid AutoGenerateColumns="False"    Name="dataGrid1"  >

                <sdk:DataGrid.Columns>

                    <sdk:DataGridTextColumn Header="Name" CanUserSort="False" Binding="{Binding Name}" />

                    <sdk:DataGridTextColumn Header="StringFormat='yyyy-MM-dd HH:mm:ss'" Binding="{Binding Birthday, StringFormat='yyyy-MM-dd HH:mm:ss'}" />

                    <sdk:DataGridTextColumn Header="'yyyy-MM-dd hh:mm:ss tt'" Binding="{Binding Birthday, StringFormat='yyyy-MM-dd hh:mm:ss tt'}" />

                    <sdk:DataGridTextColumn Header="StringFormat=g" Binding="{Binding Birthday, StringFormat=g}" />

                    <sdk:DataGridTextColumn Header="StringFormat=G" Binding="{Binding Birthday, StringFormat=G}" />

                    <sdk:DataGridTextColumn Header="StringFormat=o" Binding="{Binding Birthday, StringFormat=o}" />

                    <sdk:DataGridTextColumn Header="StringFormat=u" Binding="{Binding Birthday, StringFormat=u}" />

                    <sdk:DataGridTextColumn Header="StringFormat=U" Binding="{Binding Birthday, StringFormat=U}" />

                </sdk:DataGrid.Columns> 

            </sdk:DataGrid>

        </Grid>

2、后台代码：

  public MainPage()

 {

            InitializeComponent(); 

            dataGrid1.ItemsSource = Student.CreateStudents(); 

 }

3、绑定对象 

    public class Student

    {

        public string Name { get; set; }

        public DateTime Birthday { get; set; }

        public Student(string name, DateTime bd)

        {

            Name = name;

            Birthday = bd;

        }

        public static List<Student> CreateStudents()

        {

            List<Student> students = new List<Student>();

            students.Add(new Student("零点", new DateTime(2001, 1, 2)));

            students.Add(new Student("十二点", new DateTime(2001, 1, 2, 12, 0, 0)));

            students.Add(new Student("十四点", new DateTime(2001, 1, 2, 14, 0, 0)));

            students.Add(new Student("九点", new DateTime(2001, 1, 2, 9, 0, 0)));

            students.Add(new Student("二十四点", new DateTime(2001, 1, 2, 23, 59, 59)));

            students.Add(new Student("九点半", new DateTime(2001, 1, 2, 9, 30, 30)));

            students.Add(new Student("十二点半", new DateTime(2001, 1, 2, 12, 30, 0)));

            return students;

        }

    }
