推荐答案

DOS 8.3路径和文件名需要kernel32函数GetShortPathName:

DOS 8.3 path and file names need the kernel32 funtion GetShortPathName:

Private Declare Function GetShortPathName Lib "kernel32" Alias "GetShortPathNameA" (ByVal lpszLongPath As String, ByVal lpszShortPath As String, ByVal cchBuffer As Long) As Long

Public Function GetShortName(ByVal sLongFileName As String) As String
Dim lRetVal As Long, sShortPathName As String, iLen As Integer
sShortPathName = Space(255)
iLen = Len(sShortPathName)
lRetVal = GetShortPathName(sLongFileName, sShortPathName, iLen)
GetShortName = Left(sShortPathName, lRetVal) 
End Function

第一个示例显示了以下内容看起来像DOS短名称，因为它们是NTFS引入的，目的是与旧版软件兼容(然后此示例书写不正确:不允许使用空白字符).您是否需要与为MS-DOS或类似语言编写的代码兼容?最好一定要避免这种情况.坦率地说，我认为您真的不需要使用这些名称.

至于第二次转换，它看起来像URLEncode.使用方法System.Web.HttpServerUtility.UrlEncode， http://msdn.microsoft.com/en-us/library/zttxte6w .aspx [^ ] .

First example shows something which looks like DOS short names as they were introduced with introduction of NTFS for compatibility with legacy software (then this example is written incorrectly: blank character is not allowed). Do you need compatibility with code written for MS-DOS or something like that? Better avoid it by all means. I don''t think you really need to use such names, frankly.

As to the second conversion, it looks like URLEncode. Use the method System.Web.HttpServerUtility.UrlEncode, http://msdn.microsoft.com/en-us/library/zttxte6w.aspx[^].
