Nasreddine 的回答几乎是正确的。在您的情况下，只需指定 StringBuilder 大小:

[DllImport("shlwapi.dll", CharSet = CharSet.Auto)]
static extern bool PathCompactPathEx(
                       [Out] StringBuilder pszOut, 
                       string szPath, 
                       int cchMax, 
                       int dwFlags);

static string PathShortener(string path, int length)
{
    StringBuilder sb = new StringBuilder(length + 1);
    PathCompactPathEx(sb, path, length, 0);
    return sb.ToString();
}
