用雙擊打開listview項目vb.net

Question

我想通過雙擊打開列表視圖中的項目。

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 

這是代碼的重要組成部分，我用的onclick，但我不能似乎得到它在任何地方，任何建議的覺得呢？

我也考慮過使用和打開文件對話框，但我不認爲它可以不帶路徑的用戶的輸入來完成

我假設當你說開，你的意思是你要打開的相關文件在該文件類型的默認程序中。在這種情況下，您需要在列表視圖中存儲文件的完整路徑。這可以通過以下代碼完成：

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

     li.Tag = file.FullName 
    Next 

然後，您將需要爲listview的雙擊方法添加一個事件。在這種情況下，你會想看看選定的項目並運行它的默認程序。

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