vb.net搜索文件夹 vbnet findwindow

vb.net如何查看文件夹的权限vb.net查看文件夹权限方法:
1、右键单击获取权限的文件夹,转到安全Tab 。
2、显示了这个文件夹的权限账户 。
3、输入对应账户的名称与密码即可查看全部权限信息 。
vb.net 如何用通配符查找文件步骤如下:
窗体上添加2个列表框 , 一个按钮:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim MyDir As String = "C:\123"
'搜索并显示子文件夹
ListBox1.Items.Clear()
For Each MySubDir As String In System.IO.Directory.GetDirectories(MyDir)
ListBox1.Items.Add(MySubDir)
Next
'搜索并显示文件
ListBox2.Items.Clear()
For Each MyFile As String In System.IO.Directory.GetFiles(MyDir)
ListBox2.Items.Add(MyFile)
Next
End Sub
End Class
VB.NET遍历查找某个文件夹,并找出指定文件解压密码:1299
假设路径为C:\abc
代码:
Public Class Form1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim Files As ObjectModel.ReadOnlyCollection(Of String) = My.Computer.FileSystem.GetFiles("C:\abc")
Dim FileSize As Long, FileName As String = Nothing
Dim oFileSize As Long
For Each File As String In Files
oFileSize = My.Computer.FileSystem.GetFileInfo(File).Length
If oFileSizeFileSize Then
FileSize = oFileSize
FileName = File
End If
Next
Dim ListN As ListViewItem = New ListViewItem(My.Computer.FileSystem.GetName(FileName))
ListN.SubItems.Add(oFileSize" byte")
ListN.SubItems.Add(My.Computer.FileSystem.GetFileInfo(FileName).Extension" 文件")
ListN.SubItems.Add(FileName)
ListView1.Items.Add(ListN)
End Sub
End Class

vb.net 搜索子目录下的文件vb.net编程查找搜索指定目录下面的所有文件和其子目录下的文件 , 方法如下:
''=============================================
''名称: FindPath
''作用: 查找搜索指定目录下面的所有文件和其子目录下的文件
''参数:strPath 要查找的目录,
''strFiles 用于存查找结果的缓冲区,String 类型的动态数组,调用时事先初始化,如Redim strFiles(0)
''FileCount 用于返回文件个数
''=============================================
Public Sub FindPath(ByVal strPath As String, strFiles() As String, FileCount As Long)
Dim strDirs()As String
Dim strResultAs String
Dim FileLimitAs Long
Dim dirLimitAs Long
Dim dirCountAs Long
Dim IAs Long
FileLimit = UBound(strFiles) + 1
dirLimit = 0
If Right$(strPath, 1)"/" Then strPath = strPath"/"
strResult = Dir(strPath, vbDirectory + vbSystem + vbReadOnly + vbHidden + vbNormal + vbArchive)
Do While Len(strResult)0
If strResult"." And strResult".." Then
If (GetAttr(strPathstrResult) And vbDirectory)vbDirectory Then
If FileCount = FileLimit Then
ReDim Preserve strFiles(FileLimit + 10)
FileLimit = FileLimit + 10
End If
strFiles(FileCount) = strPathstrResult
FileCount = FileCount + 1
Else
If dirCount = dirLimit Then
ReDim Preserve strDirs(dirLimit + 10)
dirLimit = dirLimit + 10
End If
strDirs(dirCount) = strPathstrResult
dirCount = dirCount + 1
End If
End If
strResult = Dir(, vbDirectory + vbSystem + vbReadOnly + vbHidden + vbNormal + vbArchive)
Loop
For I = 0 To dirCount - 1
Call FindPath(strDirs(I), strFiles, FileCount)
Next I
End Sub
VB.NET获取目录文件夹名称Dim
dir
As
New
IO.DirectoryInfo("C:\TDDownload")
//
目录下就一个文件夹
If
dir.GetDirectories.Length
