根据您放入另一个 WPF 中的信息在 WPF 中放入一个值/打开文件

Question

我是从 C# 开始的，我的问题是他在跟进 :

我想使用带有按钮、文本框等的 WPF... 来控制（在其中显示信息和视频）另一个 WPF。

但我找不到如何与其他 WPF 正确交互。

我的 WPF 代码 windows :

我知道上面的代码没有优化。

我想了解如何通过第一个 WPF 中的输入在第二个 WPF 中显示视频。

谢谢！

您可以做很多事情。如果"play"按钮是打开第二个wpf你可以在Play_btn:

中添加click事件

private void Play_btn_Click(object sender, RoutedEventArgs e)
{
holoAvcWindow avc = new holoAvcWindow();
avc.Show();
this.Close();
}

或者你可以做 .ShowDialog(); 而不要写 this.Close(); 如果你想都打开，但用户将无法使用第一个屏幕，除非他关闭第二个屏幕。或者只删除 this.Close(); 并保留 .Show();。这样用户就可以同时使用两者。

所以我们有：

.Show() 和 this.Close()：将关闭第一个屏幕并显示 holoAcvWindow。
.Show() 没有 this.Close() 不推荐：将保持打开状态，用户将能够同时使用两者。这不是最好的选择，因为如果有一个按钮可以打开第二个 window，用户可以根据需要打开 1000 个 windows。
.ShowDialog()：将打开第二个 holoAvcWindow。将保持 MainWindow 打开，但除非 holoAvcWindow 关闭，否则用户将无法使用。

此外，如果您需要第一个屏幕向第二个屏幕发送任何内容，例如 url，只需创建一个需要参数的初始化方法。喜欢：

public holoAvcWindow(string url)
{
    InitializeComponent();
}

并像这样调用第二个屏幕：

private void Play_btn_Click(object sender, RoutedEventArgs e)
{
      holoAvcWindow avc = new holoAvcWindow(url);
      avc.Show();
      this.Close();
}

如果你想在加载程序时同时打开两个屏幕，将此添加到 main 的初始化方法中 window:

      holoAvcWindow avc = new holoAvcWindow(url);
      avc.Show();

应该是这样的：

public MainWindow()
{
    InitializeComponent();
    holoAvcWindow avc = new holoAvcWindow();
    avc.Show();
}

根据您放入另一个 WPF 中的信息在 WPF 中放入一个值/打开文件

Put a value / open files in a WPF from informations you put in another WPF

c#

wpf

xaml

wpf-controls
