Question

我想知道是否有一种简单的方法可以在一个表单上声明一个变量，然后可以在多个单独的表单上使用它。我看到了这个建议：

Public Variable_Name As String

但是它似乎无法工作，尽管将它放在公共类中并且在公共类中也引用了Variable_Name的代码。如果有人有任何他们知道会有效的建议，我们将不胜感激！

更新：表格1上的代码：

Public Class WithdrawFunds
    Public Funds As String = "0"

Public Sub Button_Withdraw_20_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button_Withdraw_20.Click
    Static Funds As String = "$20"
    Dim SlideCheckout As New Checkout
    SlideCheckout.Show()
    Me.Hide()
End Sub

结束班

表格2上的代码：

Public Class Checkout

Public Sub Checkout_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
    Label_Amount.Text = WithdrawFunds.Funds
End Sub
End Class

Answer 1

我不知道是否解决了它我认为你正在使用两个基金变量你应该尝试这样

Public Class WithdrawFunds
  Public Funds As String = "0"

Public Sub Button_Withdraw_20_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button_Withdraw_20.Click
  Funds = "$20" 
    Dim SlideCheckout As New Checkout
    SlideCheckout.Show()
    Me.Hide()
End Sub

祝你好运XD

Answer 2

把它放在一个模块中：

Public Module MyVariables
    Public Funds As String = "0"
End Module

Public Class WithdrawFunds
    Public Sub Button_Withdraw_20_Click( ... )
         MyVariables.Funds = "$20"
    End Sub
End Class

Public Class Checkout   
    Public Sub Checkout_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        Label_Amount.Text = MyVariables.Funds
    End Sub
End Class

声明可以跨多个表单使用的变量
