Winforms应用在WPF上运行应用

Question

我需要在WPF应用上托管一个WinForms应用。我按照步骤here，但我有一个错误：

System.Reflection.TargetInvocationException was unhandled Message: Se produjo una excepción en el destino de la invocación.

怎么了？我正在使用VS2012和.NET 4.5。 WinForms应用程序只有Form与Button。该事件点击显示一个MessageBox与消息Hello World没有更多。

我以前使用过WindowsFormsIntegration.dll，它工作正常。这应该有助于你开始。首先添加对WindowsFormsIntegration的引用。然后......

using System.Windows.Forms.Integration; 

...

private void Window_Loaded(object sender, RoutedEventArgs e) 
    { 
     var form = new Form1(); 
     form.TopLevel = false; 

     WindowsFormsHost host = new WindowsFormsHost(); 
     host.Child = form; 
     host.VerticalAlignment = System.Windows.VerticalAlignment.Top; 
     host.HorizontalAlignment = System.Windows.HorizontalAlignment.Left; 


     grid.Children.Add(host); 
    } 

...

<Window x:Class="WpfSandbox.MainWindow" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     Title="MainWindow" Height="350" Width="525" 
     Loaded="Window_Loaded"> 
    <Grid x:Name="grid"> 
    </Grid> 
</Window> 

现在对于简单的WinForm

public partial class Form1 : Form 
{ 
    public Form1() 
    { 
     InitializeComponent(); 
    } 

    private void button1_Click(object sender, EventArgs e) 
    { 
     MessageBox.Show("hello"); 
    } 
}
