以下是允许您停用WPF的WebBrowser上下文菜单的实用程序类的代码。它还允许您抑制脚本错误（WPF WebBrowser control - how to supress script errors?）并更改IE的DOCHOSTUIFLAG。
使用示例：
public partial class Player : Window
{
private WebBrowserHostUIHandler _wbHandler;
public Player()
{
InitializeComponent();
...
_wbHandler = new WebBrowserHostUIHandler(MyWebBrower);
_wbHandler.IsWebBrowserContextMenuEnabled = false;
}
}
实用程序代码：
public class WebBrowserHostUIHandler : Native.IDocHostUIHandler
{
private const uint E_NOTIMPL = 0x80004001;
private const uint S_OK = 0;
private const uint S_FALSE = 1;
public WebBrowserHostUIHandler(WebBrowser browser)
{
if (browser == null)
throw new ArgumentNullException("browser");
Browser = browser;
browser.LoadCompleted += OnLoadCompleted;
browser.Navigated += OnNavigated;
IsWebBrowserContextMenuEnabled = true;
Flags |= HostUIFlags.ENABLE_REDIRECT_NOTIFICATION;
}
public WebBrowser Browser { get; private set; }
public HostUIFlags Flags { get; set; }
public bool IsWebBrowserContextMenuEnabled { get; set; }
public bool ScriptErrorsSuppressed { get; set; }
private void OnNavigated(object sender, NavigationEventArgs e)
{
SetSilent(Browser, ScriptErrorsSuppressed);
}
private void OnLoadCompleted(object sender, NavigationEventArgs e)
{
Native.ICustomDoc doc = Browser.Document as Native.ICustomDoc;
if (doc != null)
{
doc.SetUIHandler(this);
}
}
uint Native.IDocHostUIHandler.ShowContextMenu(int dwID, Native.POINT pt, object pcmdtReserved, object pdispReserved)
{

}

return E_NOTIMPL;
}
uint Native.IDocHostUIHandler.FilterDataObject(IDataObject pDO, out IDataObject ppDORet)

参考mshtml
using mshtml;
然后您可以通过访问文档来执行此操作：
MainBrowser.Navigate("https://www.domain.com");
MainBrowser.LoadCompleted += (o, args) =>
{
var doc = (HTMLDocumentEvents2_Event) MainBrowser.Document;
doc.oncontextmenu += obj => false;
};
答案 2 :(得分：4)
来自内部WebBrowserSite类：
int UnsafeNativeMethods.IDocHostUIHandler.ShowContextMenu(int dwID, NativeMethods.POINT pt, object pcmdtReserved, object pdispReserved)
{
// Returning S_FALSE will allow the native control to do default processing,
// i.e., execute the shortcut key. Returning S_OK will cancel the context menu
return NativeMethods.S_FALSE;
}
很难烘焙，你无法覆盖它。将Winforms WebBrower放在WindowsFormsHost中将是一种变通方法，它有一个更聪明的方法实现，它使用IsWebBrowserContextMenuEnabled属性并允许您创建自己的上下文菜单。

这是一个老问题，但我遇到了一个独特的问题，我希望/需要在.Net Core SDK中使用较新的CSProj文件格式，但它有known issue无法引用扩展名库，例如mshtml。所以我终于找到了一个没有引用mshtml 的的解决方案。
一些灵感来自https://stackoverflow.com/a/28464764/2646868，用户将WebBrowser.Document属性转换为dynamic。
假设webView是WebBrowser控件的名称，请挂钩LoadCompleted事件，如下所示：
private void webView_LoadCompleted(object sender, NavigationEventArgs e)
{
dynamic document = webView.Document;
document.oncontextmenu += new Func<bool>(() => false);
}

似乎在挖坟墓，但是...
基于在此处@HumanWrites处获取Sub Create_Pivot_Table()
Dim destws As Worksheet, wsData As Worksheet
Dim wb As Workbook
Dim pc As PivotCache
Dim pt As PivotTable
Set wb = ThisWorkbook
Set destws = wb.Worksheets("Funding Type Breakdown")
Set wsData = wb.Worksheets("YTD")
Set pc = wb.PivotCaches.Create(SourceType:=xlDatabase, _
SourceData:=wsData.Range("QA_Allocations_YTD"))
Set pt = destws.PivotTables.Add(PivotCache:=pc, _
TableDestination:=destws.Range("E10"), TableName:="P1")
End Sub
接口，然后获取IWebBrowser2接口，并将处理程序附加到DocumentComplete事件
DWebBrowserEvents2_Event（以上必须在WebBrowser LoadCompleted事件上仅执行一次，因此添加一些逻辑使其仅在第一个上运行）
然后在此处理程序中，运行sone JavaScript将事件侦听器附加到文档，并作为奖励附加到此文档中的iframe
SHDocVw.DWebBrowserEvents2_Event wbEvents = (SHDocVw.DWebBrowserEvents2_Event)myWebBrowser2;
wbEvents.DocumentComplete += new SHDocVw.DWebBrowserEvents2_DocumentCompleteEventHandler(OnWebBrowserDocumentComplete);
即使更改iframe内容，此操作也将起作用。我将它与在WPF WebBrowser中运行的DITA WebHelp classic一起使用。
不需要mshtml参考。
