如何在VB.NET中通过名称获取标签页的索引？

' 假设你的TabControl控件名为tabControl1
' 假设你要查找的标签页名称为"TabPage2"

Dim targetTabPageName As String = "TabPage2"
Dim targetIndex As Integer = -1

For Each tabPage As TabPage In tabControl1.TabPages
    If tabPage.Name = targetTabPageName Then
        targetIndex = tabControl1.TabPages.IndexOf(tabPage)
        Exit For
    End If
Next

If targetIndex <> -1 Then
    ' 找到了匹配的标签页，可以使用targetIndex进行后续操作
    MessageBox.Show("找到了标签页的索引：" & targetIndex.ToString())
Else
    ' 没有找到匹配的标签页
    MessageBox.Show("未找到匹配的标签页")
End If
