错误事件“已加载”

Question

I don`t understand this error occurs, though I have declared this method. look at this code and error.

'WpfApplication5.MonoBehaviour' does not contain a definition for 'event_rotate' and no extension method 'event_rotate' accepting a first argument of type could be found (are you missing a using directive or an assembly reference?)

Code c# 1:

private void event_rotate(object sender, RoutedEventArgs e)
{
    MessageBox.Show("asdasada");
}

Code c# 2:

using UnityEngine;
using System.Collections;
namespace WpfApplication5
{
    /// <summary>
    /// Interaction logic for Window2.xaml
    /// </summary>
    public partial class Window2 : MonoBehaviour

Code xaml:

<Window
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" x:Class="WpfApplication5.MonoBehaviour"
    Title="Window2" Height="300" Width="300" Loaded="event_rotate">

Answer 1

the x:Class attribute has the wrong value. the x:Class attribute specifies the codebehind class that should be merged with the XAML code. you specified the MonoBehavior class in XAML. It should have been Window2. Window2 does contain the event declaration & that does not need to be public.

you can tell from the error message. after merging the files, the code exects the event_rotate method to be present in the codebehind. this method is declared in Window2 not in the specified MonoBehavior like x:Class sais.

Answer 2

The Unity MonoBehaviour class is not a WPF Window base class and is therefore not appropriate to use as the base class for your Window2 class. It could however be a property of that class (assuming you can instantiate it).

C# code:

using UnityEngine;
using System.Collections;
namespace WpfApplication5
{
    public partial class Window2 : Window
    {
        // You must implement your own MyScriptClass that has MonoBehaviour as it's
        // base class and provide an appropriate constructor to use here, in the
        // Window2 constructor or some other appropriate location.
        private MonoBehaviour _monoBehaviour = new MyScriptClass();

        // Default constructor
        public Window2()
        {
            // Set up your _monoBehaviour here

            // Initialise the WPF Window GUI object
            InitializeComponent();
        }

        // Called by the WPF FrameworkElement.Loaded Event
        public void event_rotate(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("asdasada");
        }
    }
}

XAML code:

<Window x:Class="WpfApplication5.Window2"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        mc:Ignorable="d"
        Title="Window2"
        Height="300" Width="300"
        Loaded="event_rotate"

I'm not familiar with the Unity framework and don't know how you link it's GUI implementation with the XAML Window. I'd assume that you will want to data bind an approriate UserControl container class to a public property that exposes the private _monoBehaviour implementation.
