如何在VB.NET中从另一个表单打开一个表单? [英] How to open up a form from another form in VB.NET?

问题描述

我认为这很容易.我没有使用 VB.NET 那么多，我试图通过单击按钮打开一个表单.表单不会显示，我收到一个空异常错误.

This I thought would be easy. I have not used VB.NET all that much, and I am trying to open up a form from a button click. The form will not show and I get a null exception error.

代码有什么问题?

Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) Handles Button3.Click
    Dim A
    A = AboutBox1
    A.Show()
End Sub

推荐答案

Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) _
                          Handles Button3.Click

    Dim box = New AboutBox1()
    box.Show()

End Sub
