推荐答案

你好！
所有从控件类派生的控件以及任何控件都具有属性文本.
此代码用于将窗体中的所有控件重置为空文本

Hello!
all the controls derived from Control Class and any control has the property text.
this code for reset all controls in form to empty text

Private Sub btnClear_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClear.Click
    For Each ctrl As Control In Me.Controls
        ctrl.Text = ""
    Next
End Sub

您可以使用String.Empty代替"

you can use String.Empty instead of ""

看看: ^ ]

它是用C#语言编写的，但是您会想到一种可能的简便方法.

Have a look at this: Reset all controls on form (Windows forms – C#)[^]

It''s in C#, but you will get an idea of possible easy way.
