WPF应用程序上托管的Winforms应用程序

Question

I need host a WinForms app on WPF app. I followed the steps here , but I've an error:

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

What's wrong? I'm using VS2012 and .NET 4.5. The WinForms App is only a Form with a Button . The event click show a MessageBox with a message Hello World nothing more.

I have used WindowsFormsIntegration.dll before and it works fine. this should help you get started. Add a reference to WindowsFormsIntegration first. then...

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>

and now for the simple winform

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

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