用双击打开listview项目vb.net

Question

我想通过双击打开列表视图中的项目。

Imports System.IO 
Imports System.Xml 
Public Class cv7import 

Private Sub cv7import_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
    Dim caminho As String 
    caminho = "C:\Documents and Settings\Software\Ambiente de trabalho\cv7import" 



    lstvicon.View = View.Details 
    lstvicon.GridLines = False 
    lstvicon.FullRowSelect = True 
    lstvicon.HideSelection = False 
    lstvicon.MultiSelect = True 


    lstvicon.Columns.Add("Nome") 
    lstvicon.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize) 


    Dim DI As System.IO.DirectoryInfo = New System.IO.DirectoryInfo(caminho) 

    Dim files() As System.IO.FileInfo = DI.GetFiles 

    Dim file As System.IO.FileInfo 

    Dim li As ListViewItem 
    For Each file In files 
     li = lstvicon.Items.Add(file.Name) 


    Next 

End Sub 



Private Sub btnimp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnimp.Click 

    Dim caminho As String 
    caminho = "C:\Documents and Settings\Software\Ambiente de trabalho\cv7import" 


    Dim items() As ListViewItem = lstvicon.SelectedItems.Cast(Of ListViewItem).ToArray 
    Dim csv() As String = Array.ConvertAll(items, Function(lvi) String.Join(",", lvi.SubItems.Cast(Of ListViewItem.ListViewSubItem).Select(Function(si) si.Text).ToArray)) 
    IO.File.WriteAllLines("C:\Documents and Settings\Software\Ambiente de trabalho\cv7import\teste.csv", csv) 

End Class 

这是代码的重要组成部分，我用的onclick，但我不能似乎得到它在任何地方，任何建议的觉得呢？

我也考虑过使用和打开文件对话框，但我不认为它可以不带路径的用户的输入来完成

我假设当你说开，你的意思是你要打开的相关文件在该文件类型的默认程序中。在这种情况下，您需要在列表视图中存储文件的完整路径。这可以通过以下代码完成：

For Each file In files 
     li = lstvicon.Items.Add(file.Name) 

     li.Tag = file.FullName 
    Next 

然后，您将需要为listview的双击方法添加一个事件。在这种情况下，你会想看看选定的项目并运行它的默认程序。

Private Sub lstvicon_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstvicon.DoubleClick 
    Process.Start(lstvicon.SelectedItems(0).Tag) 
End Sub
