推荐答案

您应该看看 ^ ]

文章中有一个很好的例子，但这就是表单已经打开的情况

如果没有，那么此代码段将有所帮助

You should have a look at my.application.openforms[^]

There is a good example in the article, but that is if the form is already open

If not then this code snippet will help

Public Function GetForm(ByVal Formname As String) As Form
        Dim t As Type = Type.GetType(Formname) ', True, True)
        If t Is Nothing Then
            Dim Fullname As String = Application.ProductName & "." & Formname
            t = Type.GetType(Fullname, True, True)
        End If
        Return CType(Activator.CreateInstance(t), Form)

    End Function

为什么要存储表格字符串中的名称?你不想那样做.您可以直接调用from.Show()方法.

Why are you storing form name in string? You don''t want to do that. You can directly call the from.Show() method.

拥有一个可变字符串来确定要打开的形式对我来说并不是一个好主意.

为什么没有一些枚举类型供用户选择，然后由哪种枚举类型确定要打开的表单?

Having a variable string from which you determine what form to open doesn''t sound like a good idea to me.

Why not have some enumerated types from which the user can select which then determines which form to open?
