在.net中转换为短路径的标准方法

寻找标准的防错方法将"长名称"(如"C:\ Documents and settings")转换为等效的"短名称""C:\ DOCUME~1"

我需要这个来运行我的C#应用​​程序的外部进程.如果我用"长名称"中的路径提供它,它就会失败.

如果您准备开始调用Windows API函数,则GetShortPathName()和GetLongPathName()提供此功能.

    const int MAX_PATH = 255;

    [DllImport("kernel32.dll", CharSet = CharSet.Auto)]
    public static extern int GetShortPathName(
        [MarshalAs(UnmanagedType.LPTStr)]
         string path,
        [MarshalAs(UnmanagedType.LPTStr)]
         StringBuilder shortPath,
        int shortPathLength
        );

    private static string GetShortPath(string path) {
        var shortPath = new StringBuilder(MAX_PATH);
        GetShortPathName(path, shortPath, MAX_PATH);
        return shortPath.ToString();
    }
