Xamarin.forms-使用Shell导航时传递对象

// 源页面
var myObject = new MyObject(); // 要传递的对象
await Shell.Current.GoToAsync($"destinationPage?myObject={myObject}");

// 目标页面
protected override void OnAppearing()
{
    base.OnAppearing();
    
    var myObject = (MyObject)Shell.Current.CurrentState
        .GetNavigationParameters()["myObject"];
}

// 源页面
var myObject = new MyObject(); // 要传递的对象
await Shell.Current.GoToAsync($"destinationPage?myObject={myObject}");

// 目标页面
protected override void OnAppearing()
{
    base.OnAppearing();
    
    var queryParameters = Navigation.NavigationStack.Last().Query;
    var myObject = GetObjectFromQuery(queryParameters);
}

private MyObject GetObjectFromQuery(string queryParameters)
{
    // 解析查询字符串并返回对象
}
