我正在尝试在Vb.Net 2010中搜索驱动器号(C驱动器)中的文件。找到文件路径后,我想运行可执行文件。这是我试图用来查找文件的代码:
path = Convert.ToString(IO.Directory.GetFiles("C:\", "wswc.exe", System.IO.SearchOption.AllDirectories))
当我的代码试图搜索回收站(或我无权访问的其他文件)时,会抛出UnauthorizedAccessException,并且我搜索了互联网,并且有人建议使用Try ... Catch ...结束尝试,但这对我不起作用,因为我没有使用循环,我不知道如何更改我的代码作为循环。我已经看到建议在搜索目录之前使用GetAccessControl方法测试权限的地方,但我不确定如何使用它与我当前的代码一起使用。
由于UnauthorizedAccessException,我无法测试Convert.ToString(...)所以如果这个或任何其他代码有问题,请告诉我。
我是VB.Net的新手,所以尽量让你的解释变得简单。
谢谢。

我最初问过这个问题,我现在有代码搜索所有目录中的文件。我觉得有义务发布实际的代码,以便有类似问题的人可以使用我的。我正在使用其他帐户,因为我似乎无法登录到我创建的帐户。您需要四个列表框才能运行此代码。
'Run the file if found
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim path As String
'Search for a specified file
Start_Search(ListBox1)
For k = 0 To ListBox2.Items.Count - 1
Try
ListBox2.SelectedIndex = k
path = ListBox2.SelectedItem.ToString
System.Diagnostics.Process.Start(path)
Catch ex As Exception
End Try
Next
Quit()
End Sub
'Set the root of your search
Private Sub Start_Search(ByVal listbox1 As ListBox)
Dim strroot As String
strroot = "C:\"
listbox1.Items.Add(strroot)
Search(listbox1, ListBox2)
End Sub
'Search all directories and sub-directories in the search root(s)
Private Sub Search(ByVal listbox1 As ListBox, ByVal listbox2 As ListBox)
Dim listbox4 As New ListBox
'Get all sub-directories of all items in your search root(s) (listbox1),
'clear listbox1, copy all sub-directories into listbox1
For j = 0 To listbox1.Items.Count - 1
listbox1.SelectedIndex = j
Try
For Each strfolder As String In My.Computer.FileSystem.GetDirectories(listbox1.SelectedItem.ToString)
listbox4.Items.Add(strfolder)
Dim junk = listbox4.Items.Count - 1
Next
Catch ex As Exception
End Try
Next
listbox1.Items.Clear()
listbox1 = listbox4
'every directory that throws an UnauthorizedAccessException is
'placed into listbox3. Then there is a recursive call on listbox3
'
For i = 0 To listbox1.Items.Count - 1
Try
listbox1.SelectedIndex = i
'You can place the file you are looking for in this line
listbox2.Items.AddRange(System.IO.Directory.GetFiles(listbox1.SelectedItem.ToString & "\", "File to Find.exe", System.IO.SearchOption.AllDirectories))
Catch ex As UnauthorizedAccessException
ListBox3.Items.Add(listbox1.SelectedItem.ToString)
Catch ex1 As Exception
End Try
Next
If listbox2.Items.Count > 0 Then
Return
ElseIf ListBox3.Items.Count >= 0 Then
Search(ListBox3, listbox2)
End If
Return
End Sub
我希望这段代码对某人有用。它对我有用,但可能存在漏洞。感谢您的帮助Carmelo La Monica。
