I'm using CefSharp.WinForms.ChromiumWebBrowser v45 in my project. When I right click into the web browser, the default context menu will show up:

但是我不想显示任何东西。我应该怎么办？

But I don't want to show anything. What should I do?

推荐答案

这是像我这样的懒惰人的实现。它基于CefSharp v53.0.0

This is the implementation for lazy people like me. It is based on CefSharp v53.0.0

public class CustomMenuHandler : CefSharp.IContextMenuHandler 
{
    public void OnBeforeContextMenu(IWebBrowser browserControl, IBrowser browser, IFrame frame, IContextMenuParams parameters, IMenuModel model)
    {
        model.Clear();
    }

    public bool OnContextMenuCommand(IWebBrowser browserControl, IBrowser browser, IFrame frame, IContextMenuParams parameters, CefMenuCommand commandId, CefEventFlags eventFlags)
    {

        return false;
    }

    public void OnContextMenuDismissed(IWebBrowser browserControl, IBrowser browser, IFrame frame)
    {

    }

    public bool RunContextMenu(IWebBrowser browserControl, IBrowser browser, IFrame frame, IContextMenuParams parameters, IMenuModel model, IRunContextMenuCallback callback)
    {
        return false;
    }
}

使用方法

ChromiumWebBrowser browser = new ChromiumWebBrowser();
browser.MenuHandler = new CustomMenuHandler();
