Question

我想我错过了一些明显的东西。但由于我的应用程序的主窗口是由

启动的UserControl

protected override void OnStartup(object sender, StartupEventArgs e)
{
    DisplayRootViewFor<MainWindowViewModel>();
}

在我的引导程序中如何设置窗口本身的图标和工具栏中的应用程序？

Answer 1

基于XAML的解决方案：将您的MainWindowView基类从UserControl更改为Window（在.xaml和.xaml.cs中），然后在xaml中设置您的Icon属性或任何其他特定于窗口的属性。

基于代码的解决方案：DisplayRootViewFor<T>采用可选的设置参数：

var settings = new Dictionary<string, object>
{
    { "Icon", new BitmapImage(new Uri("pack://application:,,,/WpfApplication2;component/icon.png")) },
    { "ResizeMode", ResizeMode.NoResize }
};

DisplayRootViewFor<IShell>(settings);

键应对应于您要设置的窗口属性，并且值类型必须匹配。

     private void Populate(ref IDictionary<string, object> settings)

            foreach (var prop in DefaultSettings)

    protected override System.Windows.Window CreateWindow(object rootModel, bool isDialog, object context, IDictionary<string, object> settings)

这里有一个我做事的例子。我只是将其放在窗口定义中。

let userName = req.body.userName
//wait till query result
let docs = await connection.connectedusers.updateMany({}, { $push: { connectArray: [userName] } }, { upsert: true });
//wait till query result
let list = await connection.connectedusers.find({});

//this will wait for 10 secs
await new Promise((resolve, reject) => {
    setTimeout(async () => {
     resolve(1);
    }, 10000);
});

//then process result
if (list[0].connectArray.length >= 2) {
    let shortListed = list[0].connectArray.slice(0, 2);
console.log(shortListed,'shortlisted array')
try {
    await connection.connectedusers.update({},
    { $pull: { connectArray: { $in: shortListed } } },
    { multi: true }
    );
    const docs = await connection.connectedusers.find({});
    res.json({ 
        message: 'users selected successfully',
        status: 1,
        docs: docs
    });
} catch (err) {
    res.status(201).json(err);
}
  } else {
    const docs = await connection.connectedusers.find({});
    console.log(docs, 'docs')
    const allUsers = docs.connectArray;
    console.log(allUsers, 'allUsers')
    await connection.connectedusers.update({},
      { $pull: { connectArray: { $in: allUsers } } },
      { multi: true }
    )
    res.json({
      message: 'users not selected',
      status: 2,
      docs: docs,
      allUsers: allUsers
    })
  }
