【问题描述】：

我正在 Visual Basic 2010 中制作一个名为 File Searcher 的应用程序。
它的基本作用是从用户那里获取路径和搜索查询并执行 Windows 命令行DIR 命令。我的Function如下：

Public Function GetFiles(Path$, SearchQuery$, Attributes$, SearchSubFolders As Boolean) As String()
    If Not My.Computer.FileSystem.DirectoryExists(Path) Then Return {} : Exit Function
    If Not Path.EndsWith("\") Then Path &= "\"
    SearchQuery = If(Not SearchQuery.StartsWith("*") And Not SearchQuery.StartsWith("?"), "*", "") & SearchQuery
    SearchQuery = SearchQuery & If(Not SearchQuery.EndsWith("*") And Not SearchQuery.EndsWith("?"), "*", "")
    Dim CMDProcess As New Process()
    Dim CMDProcessInfo As New ProcessStartInfo()
    Dim OutputFilePath$ = My.Computer.FileSystem.GetTempFileName
    With CMDProcessInfo
        .FileName = "CMD.EXE"
        .Arguments = "/C DIR " & Attributes & " /B" & If(SearchSubFolders, " /S", "") & " """ & SearchQuery & """>""" & OutputFilePath & """"
        .WorkingDirectory = Path
        .CreateNoWindow = True
        .UseShellExecute = False
        .RedirectStandardError = True
        .RedirectStandardOutput = True
    End With
    With CMDProcess
        .EnableRaisingEvents = True
        .StartInfo = CMDProcessInfo
        .Start()
    End With
    CMDProcess.WaitForExit()
    Dim Final() As String = IO.File.ReadAllLines(OutputFilePath)
    For Each Item$ In Final
        If Not Item.StartsWith(Path) Then Item = Path & Item
    Next
    Return Final
End Function

现在一切都很好。但问题是，当我将 *1* 作为搜索查询时，例如 DIR /A /B /S *1*，它给出了完全不同的东西。

DIR的输出：

Volume in drive C is Windows 10
Volume Serial Number is 541B-FF75

               3 Dir(s)  664,714,305,536 bytes free

对于差异，请检查两者的最后两行。对于DIR，它给出80 Files; 6 Dirs，对于DIR *1*，它给出76 Files; 3 Dirs。我只想知道*1* 是什么意思。有什么特别的吗？大多数文件/目录名称不包含 "1"！我也试过DIR *2*：

 Volume in drive C is Windows 10
 Volume Serial Number is 541B-FF75

 Directory of C:\Users\sreen\Desktop\All HTML files

               0 Dir(s)  664,134,877,184 bytes free

我的最后一个问题是：*1*或*2*是什么意思？

非常感谢任何帮助。谢谢大家！

【问题讨论】：

标签： vb.net cmd directory

【解决方案1】：

*1* 和 *2* 都是文件名的通配符。

但是，您可能启用了 8.3 短命名。在后台会生成短名称（这些可以通过dir /x 看到。生成通常使用数字，通配符同时检查长名称和短名称。

（向后兼容性很重要，但也有其自身的影响。）

【讨论】：

哦，我不知道 8dot3 名称与这些通配符一起使用。谷歌在那里没有帮助我......感谢您的友好和即时帮助！ ;-)
