Question

我的vb项目中有多个表单。 Form1是一个启动表单。有一个变量，即将整数值传递给Form2。我将Form3添加到项目中并将其作为启动表单。然后我从项目中删除它，并再次将Form1作为启动表单。但是，从那时起，Form1上的变量没有将其整数值传递给Form2。我弄乱了我的项目。有人可以帮忙???

表格1

 Public i as integer
 Private Sub btn_Click(sender As Object, e As EventArgs) Handles btn.Click
     i = 1
     dim nf as new form2
     nf.showdialog(me)
 end sub

表格2

 Private Sub Form2_Load(sender As Object, e As EventArgs) Handles MyBase.Load
     msgbox(form1.i)
 end sub

但msgbox打印值＆＃39; 0＆＃39;

好的朋友，感谢您的帮助。但是，我自己解决了。

表格1

  Private Sub btn_Click(sender As Object, e As EventArgs) Handles btn.Click
       dim nf as new form2
       nf.f2int = 1
       nf.showdialog(me)
  end sub

表格2

  Public Property f2int as Integer
  Private Sub Form2_Load(sender As Object, e As EventArgs) Handles MyBase.Load
       msgbox(f2int)
  end sub

公开声明的变量不会将值传递给另一个表单
