获得系统文件夹信息

.NET Compact Framework应用程序中调用SHGetSpecialFolderPath函数比较麻烦,下面就介绍该函数的使用方法。为了让SHGetSpecialFolderPath函数更加容易使用,可以建立一个模块,在模块中加入常用该函数的声明,然后在开发Pocket PC应用程序时使用。

调用SHGetSpecialFolderPath函数首先要为nFolder参数定义CSIDL值。清单11-1给出了CSIDL值的声明。

封装SHGetSpecialFolderPath函数

.NET Compact Framework应用程序中调用SHGetSpecialFolderPath函数比较麻烦,最好的办法就是对SHGetSpecialFolderPath函数进行封装。这里使用GetSpecialFolderPath函数来进行封装。GetSpecialFolderPath函数直接接收MyCSIDL参数,返回对应的系统文件夹路径。GetSpecialFolderPath函数如清单11-3所示。

在清单11-3里,首先为返回系统文件夹的路径开辟260个字符的内存缓冲区。当SHGetSpecialFolderPath函数返回的时候,接收的路径存储在字符串的左端,以空字符(ASCII 0)结尾。

GetSpecialFolderPath函数简化了SHGetSpecialFolderPath函数的调用。以下是接收PersonalProgramsStart MenuStartup系统文件夹的示例。
