Q1: 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
Q2: vb.net从文件路径中获取文件名
获取方法vb.net查询文件名,参考实例如下vb.net查询文件名:
'获取路径名各部分: 如vb.net查询文件名: c:\dir1001\aaa.txt
'获取路径路径 c:\dir1001\
Public Function GetFileName(FilePathFileName As String) As String '获取文件名 aaa.txt
On Error Resume Next
Dim i As Integer, J As Integer
i Len(FilePathFileName)
J InStrRev(FilePathFileName, "\")
GetFileName Mid(FilePathFileName, J + 1, i)
End Function
''获取路径路径 c:\dir1001\
Public Function GetFilePath(FilePathFileName As String) As String '获取路径路径 c:\dir1001\
On Error Resume Next
Dim J As Integer
J InStrRev(FilePathFileName, "\")
GetFilePath Mid(FilePathFileName, 1, J)
End Function
'获取文件名但不包括扩展名 aaa
Public Function GetFileNameNoExt(FilePathFileName As String) As String '获取文件名但不包括扩展名 aaa
On Error Resume Next
Dim i As Integer, J As Integer, k As Integer
i Len(FilePathFileName)
J InStrRev(FilePathFileName, "\")
k InStrRev(FilePathFileName, ".")
If k 0 Then
GetFileNameNoExt Mid(FilePathFileName, J + 1, i - J)
Else
GetFileNameNoExt Mid(FilePathFileName, J + 1, k - J - 1)
End If
End Function
'===== '获取扩展名 .txt
Public Function GetFileExtName(FilePathFileName As String) As String '获取扩展名 .txt
On Error Resume Next
Dim i As Integer, J As Integer
i Len(FilePathFileName)
J InStrRev(FilePathFileName, ".")
If J 0 Then
GetFileExtName ".txt"
Else
GetFileExtName Mid(FilePathFileName, J, i)
End If
End Function
Q3: 如何用VB获得某一目录下的所有文件和文件夹名称?
Dim a() As String
Private Sub Dir1_Change()
File1.Path = Dir1.Path
Label1.Caption = Dir1.Path
End Sub
Private Sub Drive1_Change()
On Error GoTo err1
Dir1.Path = Drive1.Drive
Exit Sub
err1:

Private Sub Command1_Click()
Dim i As Integer, j As Integer
Dim ifieldcount As Integer, irecordcount As Integer
Dim wdapp As Word.Application
Dim wddoc As Word.Document
Dim atable As Word.Table
If Option2.Value = True Then
ReDim a(1 To File1.ListCount)
For i = 1 To File1.ListCount
b = File1.List(i)
a(i) = b
Next
End If
If Option1.Value = True Then
ReDim a(1 To Dir1.ListCount)
For i = 1 To Dir1.ListCount
b = Dir1.List(i)
a(i) = b

这段程序 复制过去 就行了 创建的控件有 两个option 让你选择 要提取文件夹 还是文件路径的 选中option 1 就是提取文件夹的 option2 就是提取文件的 然后再创建 Drive1 Dir1 File1 这三个 选择文件路径的 控件 再加一个 command 按钮 就行了 有疑问再联系我!!!!!这个 只是 文件路径 你看看 是你想要的话 我再给你写 提取文件夹和文件名的代码!!!!
Q4: vb.net查找文件问题
思路:
1,使用ListBox1控件来存放搜索到的文件名,然后ListBox1.SelectedItem就可以返回选中项的文本;
2,利用获得的选中项文本(即文件与路径),使用打开文本文件的方法,读取内容显示在文本框里。
