C#引用CefSharp 在C#的设计界面，添加panel控件用来放置CEFSharp浏览器。 CEFSharp浏览器dll添加引用
using CefSharp; using CefSharp.WinForms; 1 2 CEFSharp浏览器初始化代码：
public Form1() { InitializeComponent(); InitBrowser(); } public ChromiumWebBrowser browser; public void InitBrowser() { Cef.Initialize(new CefSettings()); browser = new ChromiumWebBrowser(“http://my.csdn.net/u013564470”); browser.Dock = DockStyle.Fill; panel1.Controls.Add(browser); }
上述完成之后就可以运行了！ 注意事项：平台选择X86，右侧解决方案中引用DLL文件，文件放在\项目名\bin\x86\Debug
C#添加代码屏蔽鼠标右键 在屏蔽之前先查看namespace CefSharp.WinForms内的代码
public class ChromiumWebBrowser : Control, IWebBrowserInternal, IWinFormsWebBrowser, IWebBrowser, IDisposable { public ChromiumWebBrowser(string address);
public IDownloadHandler DownloadHandler { get; set; } public ILoadHandler LoadHandler { get; set; } public IDisplayHandler DisplayHandler { get; set; } public IContextMenuHandler MenuHandler { get; set; } public IRenderProcessMessageHandler RenderProcessMessageHandler { get; set; } public IFindHandler FindHandler { get; set; } public IRequestHandler RequestHandler { get; set; } public IFocusHandler FocusHandler { get; set; } public IResourceHandlerFactory ResourceHandlerFactory { get; set; } public IGeolocationHandler GeolocationHandler { get; set; } public bool CanGoForward { get; } public bool CanGoBack { get; } public bool IsBrowserInitialized { get; } public override bool Focused { get; } public IDragHandler DragHandler { get; set; } public IKeyboardHandler KeyboardHandler { get; set; } public ILifeSpanHandler LifeSpanHandler { get; set; } public IDialogHandler DialogHandler { get; set; } public string Address { get; } public string TooltipText { get; } public bool IsLoading { get; } public RequestContext RequestContext { get; set; } public BrowserSettings BrowserSettings { get; set; } public bool IsActivating { get; set; } public IJsDialogHandler JsDialogHandler { get; set; } public event EventHandler<AddressChangedEventArgs> AddressChanged; public event EventHandler<StatusMessageEventArgs> StatusMessage; public event EventHandler<ConsoleMessageEventArgs> ConsoleMessage; public event EventHandler<LoadingStateChangedEventArgs> LoadingStateChanged; public event EventHandler<FrameLoadEndEventArgs> FrameLoadEnd; public event EventHandler<FrameLoadStartEventArgs> FrameLoadStart; public event EventHandler<LoadErrorEventArgs> LoadError; public event EventHandler<IsBrowserInitializedChangedEventArgs> IsBrowserInitializedChanged; public event EventHandler<TitleChangedEventArgs> TitleChanged; public IBrowser GetBrowser(); public void Load(string url); public void RegisterAsyncJsObject(string name, object objectToBind, bool camelCaseJavascriptNames = true); public void RegisterJsObject(string name, object objectToBind, bool camelCaseJavascriptNames = true); protected override void Dispose(bool disposing); protected override void OnGotFocus(EventArgs e); protected override void OnHandleCreated(EventArgs e); protected override void OnSizeChanged(EventArgs e);}
我们在其中的public IContextMenuHandler MenuHandler { get; set; }接口中更改鼠标右键事件。 方法为继承该类接口，并重写。实现方式如下：
public class MenuHandler : 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; } }
定义完之后在CEFSharp代码初始化中引用。如下：
public ChromiumWebBrowser browser; public void InitBrowser() { Cef.Initialize(new CefSettings()); browser = new ChromiumWebBrowser(“http://my.csdn.net/u013564470”); browser.MenuHandler = new MenuHandler(); browser.Dock = DockStyle.Fill; panel1.Controls.Add(browser); } 1 2 3 4 5 6 7 8 9 之后运行，会发现已经屏蔽鼠标右键。
C#添加代码屏蔽拖动放置事件 屏蔽拖动放置事件和屏蔽鼠标右键类似。我们在其中的public IDragHandler DragHandler { get; set; }接口中更改拖动放置事件。 方法为继承该类接口，并重写。实现方式如下：
public class DragHandler : IDragHandler { public bool OnDragEnter(IWebBrowser browserControl, IBrowser browser, IDragData dragData, DragOperationsMask mask) { return true;// false;//throw new NotImplementedException(); } public void OnDraggableRegionsChanged(IWebBrowser browserControl, IBrowser browser, IList regions) { //throw new NotImplementedException(); } }
return true;为禁止。定义完之后在CEFSharp代码初始化中引用。如下：
public ChromiumWebBrowser browser; public void InitBrowser() { Cef.Initialize(new CefSettings()); browser = new ChromiumWebBrowser(“http://my.csdn.net/u013564470”); browser.MenuHandler = new MenuHandler(); browser.DragHandler = new DragHandler(); browser.Dock = DockStyle.Fill; panel1.Controls.Add(browser); }
之后运行，会发现已经屏蔽鼠标右键和拖动放置事件。
