c#转化成vb遇到的问题
大家好：
以下是一段c#代码
string F_name;
  string Path = Server.MapPath(".");
  DirectoryInfo di=new DirectoryInfo(Path);
  foreach(FileSystemInfo fsi in di.GetFileSystem())
  {
  if (fsi is FileInfo)
  {
  FileInfo fi = (FileInfo)fsi;
  F_name = fi.Name;
  }
  else
  {
  di = (Directory)fsi;
  F_name = di.Name;
  }
  }

我试着转化成vb去做，按如下代码： 


Dim F_name As String
  Dim Path As String = Server.MapPath(".")
  Dim di As DirectoryInfo = New DirectoryInfo(path) 'new出一个DirectoryInfo对象用于枚举所有的项
  Dim fsi As FileSystemInfo
  For Each fsi In di.GetFileSystemInfos() 'GetFileSystemInfos是一个文件夹中所有文件的子目录的强类型FileSystemInfo项数组
  '迭代数组中的每一项
  Dim fi As FileInfo
  If fsi Is FileInfo Then
  fi=(FileInfo)fsi
  F_name = fi.Name  
  Else
  di=(DirectoryInfo)fsi
  F_name = di.Name
  End If

一共有四句出现了波浪线。c＃里面的di.GetFileSystem()到了vb里面成了di.GetFileSystemInfos() ，
还有fsi Is FileInfo，以及强制类型转换fi=(FileInfo)fsi，di=(DirectoryInfo)fsi都出错。
我不明白在vb里这几句怎样写才合适。请教！谢谢！

你的c#代码本身就是有错误了，转为vb.net稍做了修改，现在是正确的

VB.NET code

        Dim F_name As String        Dim Path As String = Server.MapPath(".")        Dim di As New DirectoryInfo(Path)        For Each fsi As FileSystemInfo In di.GetFileSystemInfos()            If (TypeOf (fsi) Is FileInfo) Then                Dim fi As FileInfo = CType(fsi, FileInfo)                F_name = fi.Name            Else                di = CType(fsi, DirectoryInfo)                F_name = di.Name            End If        Next
