物業子項目是隻讀的，更

Question

嘗試到C＃轉換爲VB，但我不斷收到以下錯誤：

物業子項目是隻讀

和String類型（的

值）不能轉換到ListViewItem.ListViewSubItemCollection

我的代碼如下：

ListView1.Items.Clear() 
     For int_0 As Integer = 0 To 17 
      Dim tuple As Tuple(Of String, String, String) = pullMem(int_0) 
      If tuple.Item3.Contains("09") Then 
       Me.ListView1.Items.Add(New ListViewItem(tuple.Item1) With { 
          .SubItems = {tuple.Item2, tuple.Item3} 
         }) 
      End If 
     Next int_0 
    Catch e1 As Exception 
     MessageBox.Show("You must connect first!", "Error") 
    End Try

是的，你不能像VB.Net那樣實例化子項。嘗試創建ListView項目，然後將子項目添加到它：

Dim lvi As New ListViewItem(tuple.Item1) 
lvi.SubItems.AddRange({tuple.Item2, tuple.Item3}.ToArray()) 
ListView1.Items.Add(lvi)
