WPF中使用webbrowser并且屏蔽在新窗口中打开页面
此代码为从网上找到的方法,然后整理成一个文件方便引用
首先创建一个类文件 WebBrowserHelper.cs
复制代码using System;

{
private WebBrowser _webBrowser;
private object _cookie;
public event CancelEventHandler NewWindow;
public WebBrowserHelper(WebBrowser webBrowser)
{
if (webBrowser == null)
throw new ArgumentNullException("webBrowser");
_webBrowser = webBrowser;
_webBrowser.Dispatcher.BeginInvoke(new Action(Attach), DispatcherPriority.Loaded);
}
public void Disconnect()
{
if (_cookie != null)
{
_cookie.ReflectInvokeMethod("Disconnect", new Type[] { }, null);
_cookie = null;
}
}
private void Attach()
{
var axIWebBrowser2 = _webBrowser.ReflectGetProperty("AxIWebBrowser2");
var webBrowserEvent = new WebBrowserEvent(this);
var cookieType = typeof(WebBrowser).Assembly.GetType("MS.Internal.Controls.ConnectionPointCookie");
_cookie = Activator.CreateInstance(
cookieType,
ReflectionService.BindingFlags,
null,
new[] { axIWebBrowser2, webBrowserEvent, typeof(DWebBrowserEvents2) },
CultureInfo.CurrentUICulture);
}
private void OnNewWindow(ref bool cancel)
{
var eventArgs = new CancelEventArgs(cancel);
if (NewWindow != null)
{
NewWindow(_webBrowser, eventArgs);
cancel = eventArgs.Cancel;
}
}
}
public static class ReflectionService
{
public readonly static BindingFlags BindingFlags =
BindingFlags.Instance |
BindingFlags.Public |
BindingFlags.NonPublic |
BindingFlags.FlattenHierarchy |
BindingFlags.CreateInstance;
public static object ReflectGetProperty(this object target, string propertyName)
{
if (target == null)
throw new ArgumentNullException("target");
if (string.IsNullOrWhiteSpace(propertyName))
throw new ArgumentException("propertyName can not be null or whitespace", "propertyName");
var propertyInfo = target.GetType().GetProperty(propertyName, BindingFlags);
if (propertyInfo == null)
throw new ArgumentException(string.Format("Can not find property '{0}' on '{1}'", propertyName, target.GetType()));
return propertyInfo.GetValue(target, null);
}
public static object ReflectInvokeMethod(this object target, string methodName, Type[] argTypes, object[] parameters)
{
if (target == null)
throw new ArgumentNullException("target");
if (string.IsNullOrWhiteSpace(methodName))
throw new ArgumentException("methodName can not be null or whitespace", "methodName");

}
}

然后添加一个webbrowser控件
