Question

我收到错误“未为类型'String'和'CheckBox'定义Visual Basic运算符'＆'。”这是有问题的代码块

If cb_Surfacearea.Checked = True AndAlso cb_Volume.Checked = True Then
   Me.richtxtbox.Text = "Surface area for" & variable_sphere & " = " & cb_Surfacearea & ControlChars.NewLine & "Volume For" & variable_sphere & " = " & cb_Volume

Answer 1

您可以使用类似的东西

richtxtbox.Text = "Surface area for" & variable_sphere & " = " & cb_Surfacearea.Text & ControlChars.NewLine & "Volume For" & variable_sphere & " = " & cb_Volume.Text

尚不清楚您在其中使用什么上下文。我假设cb_Volume和cb_Surfacearea是复选框？

没有为类型'String'和'CheckBox'定义Visual Basic运算符'＆'。错误
