VB.NET删除文件夹实现方法介绍
编程人员在使用了VB.NET语言进行编程时,就会发现这款语言可以极大程度的提高我们的程序开发效率。比如在对文件夹的操作方面等等。那么今天大家就可以通过对VB.NET删除文件夹的操作的解读,来具体了解这一特性。
VB.NET删除文件夹的操作是采用递归算法删除带有多级子目录的目录
Option Explicit
Private Sub Command1_Click()
Dim strPathName As String
strPathName = ""
strPathName = InputBox("请输入需要删除的文件夹名称∶", "删除文件夹")
If strPathName = "" Then Exit Sub
On Error GoTo ErrorHandle
SetAttr strPathName, vbNormal '此行主要是为了检查文件夹名称的有效性
RecurseTree strPathName
Label1.Caption = "文件夹" & strPathName & "已经删除!"
Exit Sub
ErrorHandle:
MsgBox "无效的文件夹名称:" & strPathName
End Sub
Sub RecurseTree(CurrPath As String)
Dim sFileName As String
Dim newPath As String
Dim sPath As String
Static oldPath As String
sPath = CurrPath & "/"
sFileName = Dir(sPath, 31) '31的含义∶31=vbNormal+vbReadOnly+
vbHidden+vbSystem+vbVolume+vbDirectory
Do While sFileName <> ""
If sFileName <> "." And sFileName <> ".." Then
If GetAttr(sPath & sFileName) And vbDirectory Then '如果是目录和文件夹
newPath = sPath & sFileName
RecurseTree newPath
sFileName = Dir(sPath, 31)
Else
SetAttr sPath & sFileName, vbNormal
Kill (sPath & sFileName)
Label1.Caption = sPath & sFileName '显示删除过程
sFileName = Dir
End If
Else
sFileName = Dir
End If
DoEvents
Loop
SetAttr CurrPath, vbNormal
RmDir CurrPath
Label1.Caption = CurrPath
End Sub
