Question

vb.net中如何将多个控件事件引用同一方法（不同控件事件引用方法的参数不同）统一写在同一事件中？

如（TextChanged（文本框控件）是一个带参数的的方法）：
Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged
TextChanged(TextBox1)
End Sub

Private Sub TextBox2_TextChanged(sender As Object, e As EventArgs) Handles TextBox2.TextChanged
TextChanged(TextBox2)
End Sub

两个事件都是调用TextChanged(文本框控件)方法，但参数分别是TextBox1和TextBox2，如何将这两个事件合并起来写

Answer 1

Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged,TextBox2.TextChanged

Try

If CType(sender,TextBox1).Tag = "0" Then

'TextBox1.textChanged更改

ElseIf CType(sender, Button).Tag = "1" Then

'TextBox2.TextChanged更改

End If

Catch ex As Exception

MsgBox("错误" & ex.Message)

End Try

End Sub

'先把TextBox1.Tag设为0;先把TextBox2.Tag设为1(也可以把其它的属性来示别)
