在 WPF 窗口之间传递数据 [英] Pass data between WPF windows

问题描述

我有一些代码可以在 winforms 中运行，但显然不能在 WPF 中运行，代码如下:这是全局设置的:

I have some code that works in winforms, but not in WPF apparently, the code is as follows: This is set globally:

Private Property avar As Object
Public main As MainWindow
Public charchoice As Char

然后在Window Loaded子中，放置:

And then in the Window Loaded sub, this is placed:

charchoice = main.charchoice

问题是，下一个窗口没有选择这个变量，那么我怎样才能让它识别和使用它呢?谢谢各位

Thing is, the next window doesn't pick up this variable, so how can I make it recognise and use it? Thanks Guys

推荐答案

嘿，我在两个表单之间传递值时遇到了同样的问题.我使用一个简单的类和 Shared 属性找到了它的解决方案.

Hey i got same problem when i am going to pass values between two forms. I find its solution using a simple class and Shared property.

首先我创建一个名为 cls_pass_val 的类，如下所示:-

First I create a class named with cls_pass_val which is as under:-

Public Class cls_pass_val
    Private Shared var_pass_val As String = ""
    Public Shared Property Pass_val() As Char
        Get
            Return var_pass_val
        End Get
        Set(ByVal value As String)
            var_pass_val = value
       End Set
    End Property
End Class    

现在在赋值时:
cls_pass_val.Pass_val='A'

并在检索值时:

Dim var_c as Char
var_c=cls_pass_val.Pass_val
