如何使用C＃链接两个Wpf Windows

问题描述

我有两个WPF窗口，即 MainWindow 和 Window1 。在 MainWindow 我有一个文本框（ textbox1 ）和一个按钮，在 Window1 中我有一个文本框（ textbox2 ） 。



我想要完成的是当我点击按钮时， textbox1 中输入的内容现在显示在 textbox2中。



我相信我的xaml对于两个窗口都是正确的，我在我的中添加了private void button_click_1 ..... MainWindow.cs 的。但是当我尝试输入动作时：



textbox2.Text = textbox1.Text;



它无法识别 textbox2





我是WPF的新手c＃所以任何帮助将不胜感激。谢谢

I have two WPF windows, that is MainWindow and Window1. In MainWindow i have a textbox(textbox1) and a button, in Window1 i have a textbox(textbox2).

What i am trying to accomplish is that when i click the button, whatever is typed in textbox1 is now displayed in textbox2.

my xaml i believe is correct for both windows and i have added the "private void button_click_1....." in my MainWindow.cs. however when ever i try to type the action:

textbox2.Text = textbox1.Text;

it does not recognize textbox2


I am fairly new to WPF and c# so any assistance would be appreciated. Thanks

推荐答案

public void ShowWindow1Screen(Window1ViewModel window1ViewModel)
       {
           Window1= new Window1();
           Window1.DataContext = window1ViewModel)
           Window1.Owner = nicknameView;
           Window1.ShowDialog();
       }

然后。





创建NavigationService实例.cs类MainWindowViewModel文件。

然后

then.


Create instance of NavigationService.cs class MainWindowViewModel file.
then

Window1ViewModel window1ViewModel = new Vindow1ViewModel();
window1ViewModel.Name = MainWindowTextValue;
NavigationService navigationService = new NavigationService();
navigationService.ShowWindow1Screen(window1ViewModel);
