我需要在WPF应用程序上托管一个WinForms应用程序。我遵循了这里的步骤,但我有一个错误:
System.Reflection。TargetInvocationException未处理消息:Se producjo una excepción en el destino de la invocación.
怎么了?我正在使用VS2012和。net 4.5。WinForms应用程序只是一个Form
与Button
。
MessageBox
,显示Hello World
消息。
我以前使用过WindowsFormsIntegration.dll,它工作得很好。这将帮助你开始。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>
现在是简单的winform
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show("hello");
}
}
