C# webBrowser(wpf/winform) 互调js

1.winform

[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
[ComVisible(true)]
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
this.Load += Form1_Load;
}

private void Form1_Load(object sender, EventArgs e)
{
webBrowser1.ObjectForScripting = this;//具体公开的对象,这里可以公开自定义对象
webBrowser1.Navigate(Application.StartupPath + "/dom.html");
}

private void button1_Click(object sender, EventArgs e)
{
webBrowser1.Document.InvokeScript("Run", new object[] { "test" });
}

public void ShowMsg(string msg)
{
MessageBox.Show(msg);
}

}

2.wpf

public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
this.Loaded += MainWindow_Loaded;
}

private void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
this.webBrowser1.ObjectForScripting = new OprateBasic();
Uri uri = new Uri(@"pack://application:,,,/dom.html");
Stream source = Application.GetResourceStream(uri).Stream;
webBrowser1.NavigateToStream(source);
}

private void btn1_Click(object sender, RoutedEventArgs e)
{
webBrowser1.InvokeScript("Run", new object[] { "test" });
}
}

[ComVisible(true)] // 将该类设置为com可访问
public class OprateBasic
{
public void ShowMsg(string msg)
{
MessageBox.Show(msg);
}
}
