4天玩转wp7的第二天作业

主要的一些代码：

using System;
using System.Windows;
using System.Windows.Controls;
using Microsoft.Phone.Controls;

namespace WindowsPhoneApplication1
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
        }

        private void oKButton_Click(object sender, RoutedEventArgs e)
        {
            Agent newAgent = new Agent();
            newAgent.AgentName = agent.Text.Trim ();         //textBlock里面的内容一般要去除空格trim();
            newAgent.IsUndercover = undercoverCheckBox.IsChecked;
            if (ciaRadioButton.IsChecked == true)
            {
                newAgent.Agency = "cia";
            }
            else if (mi6RadioButton.IsChecked == true)
            {
                newAgent.Agency = "mi6";
            }
            else
                newAgent.Agency = "nsa";

            ListBoxItem lbi = (ListBoxItem)ProficinciesListBox.SelectedItem;  //为什么不能直接将selectedItem转换成string类型呢？
            newAgent.Proficiency = (string)lbi.Content;

            newAgent.RecordCreateDateTime = DateTime.Now;

            newAgent.Save();

            agent.Text = "";
            undercoverCheckBox.IsChecked = false;
            ciaRadioButton.IsChecked = false;
            mi6RadioButton.IsChecked = false;
            nsaRadioButton.IsChecked = false;
            ProficinciesListBox.SelectedItem = null;

 

        }
    }
}

创建的Agent类：

using System;

namespace WindowsPhoneApplication1
{
    public class Agent
    {
        public string  AgentName { get; set; }
        public string  Agency { get; set; }
        public bool?  IsUndercover { get; set; }    //bool类型后面加一个?表示只可以为null
        public string  Proficiency { get; set; }
        public DateTime  RecordCreateDateTime { get; set; } 

        public void Save()
        {
                     //此处省略。。。
        }
    }
}
