传递给另一个表单，VB.NET 的变量值 [英] Variable Value Passing to another Form, VB.NET

问题描述

我确实有两个公共变量，每个都来自两种不同的形式..

I do have Two Public Variables, each are from two different forms..

Form1.VB
Public UserNo As String

Form2.VB
Public MyUserNo As String

在我的 Form2.VB 文件中，我为 Form1.VB 的 UserNo 赋值

On my Form2.VB File, I assign value to the UserNo of Form1.VB

Form1.UserNo = MyUserNo

每次访问 Form1.VB 时，MyUserNo 的值都为空，我该怎么办?两个表单都没有关闭.

Whenever I access the Form1.VB, the Value of the MyUserNo got empty, What should I do? Both Forms are not closed.

当我需要在 Form1.VB 上使用它时，我也尝试重新分配该值

I also tried to re-assign the value when I need to use it on the Form1.VB

UserNo = Form2.MyUserNo

推荐答案

First Correct is Syntax is:

Form1.VB
Public UserNo As String

Form2.VB
Public MyUserNo As String

In Form1
UserNo=Form2.MyUserNo

第二件事:首先，您应该先在 MyUserNo 中存储一些值，然后再将其存储到 UserNo 中.这就是为什么你得到空值.

Second Thing: First you should store some value in MyUserNo before storing it into UserNo. That's why you are getting empty value.
