Vb.net 使用PrintDocument打印组合框的所有项目

我试图打印程序中组合框的所有内容，编号为

组合框1内容：

Yes

No

Maybe

No Opinion

到目前为止，我的PrintDocument1代码：

Private Sub PrintDocument1_PrintPage(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
    Dim horizontalPrintPosition As Single
    Dim verticalPrintPosition As Single
    Dim PrintFont As New Font("Arial", 12)
    e.Graphics.DrawString("Info from ComboBox1 would go here", PrintFont, Brushes.Black, horizontalPrintPosition, verticalPrintPosition)
End Sub

例如，所需的输出为：

1. Yes

2. No

3. Maybe

4. No Opinion

谢谢

您需要遍历

组合框

Items集合来获取您的值，类似这样的内容

Private Sub PrintDocument1_PrintPage(sender As System.Object, e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
    Dim horizontalPrintPosition As Single
    Dim verticalPrintPosition As Single
    Dim PrintFont As New Font("Arial", 12)

    For x = 0 To ComboBox1.Items.Count - 1
        e.Graphics.DrawString((x + 1).ToString() & ". " & ComboBox1.Items(x).ToString(), PrintFont, Brushes.Black, horizontalPrintPosition, verticalPrintPosition)
        verticalPrintPosition += PrintFont.Height
    Next

End Sub

您发布的代码似乎与您的问题无关。您试图打印的编号版本是什么？
