如果不存在,如何在VB中创建文件夹？

Question

我给自己写了一个小的下载应用程序,这样我就可以轻松地从我的服务器中获取一组文件,并将它们全部放到一台干净安装Windows的新电脑上,而无需实际上网.不幸的是我在创建我想要放入的文件夹时遇到问题,我不确定如何去做.

我希望我的程序能够下载应用程序 program files\any name here\

所以基本上我需要一个函数来检查文件夹是否存在,如果不存在则创建它.

Answer 1

If(Not System.IO.Directory.Exists(YourPath)) Then
    System.IO.Directory.CreateDirectory(YourPath)
End If

Answer 2

在System.IO下,有一个名为Directory的类.请执行下列操作:

If Not Directory.Exists(path) Then
    Directory.CreateDirectory(path)
End If

它将确保目录在那里.

Answer 3

由于问题没有指定.NET,因此这应该适用于VBScript或VB6.

Dim objFSO, strFolder
strFolder = "C:\Temp"
Set objFSO = CreateObject("Scripting.FileSystemObject")
If Not objFSO.FolderExists(strFolder) Then
   objFSO.CreateFolder(strFolder)
End If

Answer 4

试试System.IO.DirectoryInfo类.

来自MSDN的示例:

Imports System
Imports System.IO

Public Class Test
    Public Shared Sub Main()
        ' Specify the directories you want to manipulate.
        Dim di As DirectoryInfo = New DirectoryInfo("c:\MyDir")
        Try
            ' Determine whether the directory exists.
            If di.Exists Then
                ' Indicate that it already exists.
                Console.WriteLine("That path exists already.")
                Return
            End If

            ' Try to create the directory.
            di.Create()
            Console.WriteLine("The directory was created successfully.")

            ' Delete the directory.
            di.Delete()
            Console.WriteLine("The directory was deleted successfully.")

        Catch e As Exception
            Console.WriteLine("The process failed: {0}", e.ToString())
        End Try
    End Sub
End Class

Answer 5

试试这个:Directory.Exists(TheFolderName)和Directory.CreateDirectory(TheFolderName)

(您可能需要:Imports System.IO)

Answer 6

VB.NET？System.IO.Directory.Exists(字符串路径)
