Phone 7编程点滴

1. 修改文件名

1 public static void Move(string sourceFileName, string destFileName);

2.得到运行的EXE文件所在目录

 1 /*函数功能： 获取程序所在路径 */
 2 public static string GetAppPath()
 3 {
 4     string usrdir;
 5     usrdir = System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase;
 6     usrdir = System.IO.Path.GetDirectoryName(usrdir);
 7     return usrdir;
 8 }
 9 // or:
10 Path.GetFullPath(Assembly.GetExecutingAssembly().GetName().CodeBase();

3. WP7数据存储方法

(1) 数据库、本地文件

(2) 全局域

(3) 将数据通过网络传送给服务端

(4) Isolate Storage

4. Windows Phone 7 使用GPS得到的坐标得到城市名（应该是根据坐标获取附近的POI名称）?
