为了取得最佳业绩,你应减少通俗形式的道路。 这就是8.3(GetShortPathName)和下级。

这是C#样本。 如果你使用其他某种语言的话,这个想法就是一样的。 利用GetLongPathName和(或)GetShortPathName,从Ckernel32.dll中比较:

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

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


function bool PathsAreEqual(string path1, string path2)
{
    StringBuilder shortPath1 = new StringBuilder(255);
    StringBuilder shortPath2 = new StringBuilder(255);
    GetShortPathName(path1, shortPath1, shortPath1.Capacity);
    GetShortPathName(path2, shortPath2, shortPath2.Capacity);

    return shortPath1.ToString().ToLower() == shortPath2.ToString().ToLower();

}
