cefsharp 与webbrowser简单对比概述
有个项目需要做个简单浏览器，从网上了解到几个相关的组件有winform自带的IE内核的WebBrowser，有第三方组件谷歌内核的webkit、cefsharp、chromiumfx等。
一开始是用的webbrowser 后来发现有些css样式是不兼容的于是又开始研究webkit这个有些css样式同样不能用，然后才开始研究cefsharp，从网上下载了57版本的但总是运行不起来后来发现装上vs中C++公共工具才行（注意即使装上vcredist_x86这个运行库也是不行），这个你不能要求人家客户装vs啊，后来也没找到到底是哪个动态库的问题。之后就下载了47版本。
按键事件
不同于webbrowser通过事件PreviewKeyDown捕获键盘按键，cefsharp是通过实现接口IKeyboardHandler赋值委托KeyboardHandler来实现的
web.KeyboardHandler = new CefKeyboardHandler(m_cell as CellControl); public class CefKeyboardHandler : IKeyboardHandler
{
private CellControl m_cell;
/// <summary>
/// 命名代理
/// </summary>
/// <param name="con"></param>
/// <param name="text"></param>
private delegate void PreKeyEventHandler(object sender,object webBrowser,int windowsKeyCode);
public CefKeyboardHandler(CellControl cell)
{
m_cell = cell;
}
public bool OnKeyEvent(IWebBrowser browserControl, IBrowser browser, KeyType type, int windowsKeyCode, int nativeKeyCode, CefEventFlags modifiers, bool isSystemKey)
{
return true;
}
public bool OnPreKeyEvent(IWebBrowser browserControl, IBrowser browser, KeyType type, int windowsKeyCode, int nativeKeyCode, CefEventFlags modifiers, bool isSystemKey, ref bool isKeyboardShortcut)
{
m_cell.Invoke(new PreKeyEventHandler(PreKeyEvent),m_cell, browserControl, windowsKeyCode);
return true;
}
private void PreKeyEvent(object sender, object webBrowser, int windowsKeyCode)
{
CellControl cell = sender as CellControl;
cell.ControlPreviewKeyDown(webBrowser , new System.Windows.Forms.PreviewKeyDownEventArgs((Keys)windowsKeyCode));
if (windowsKeyCode == (int)(Keys.Delete))
{
cell.Controls.Clear();
}
}代理设置
公司网络是需要代理才能上外网，webbrowser可以自动获取已经设置好的代理，cefsharp网上说可以通过setting.CefCommandLineArgs.Add("--proxy-server", "http://127.0.0.1:8877");这个方式设置代理，可是不知道为啥我这边一直不行，后来发现一个通过实现接口IRequestHandler赋值委托RequestHandler来设置代理可行
webBrowser.RequestHandler = new CefRequest(); public class CefRequest : IRequestHandler
{

}其他的ChromiumWebBrowser.Handler同上
JavaScript互调
在webbrowser中通过设置
[System.Runtime.InteropServices.ComVisible(true)]
public class JavaScripAction
webBrowser1.ObjectForScripting
= new JavaScripAction();
就可在javascrip中通过window.external来调用C#类JavaScriptAction中的方法，在C#中通过来调用javascrip中的函数
web.RegisterJsObject("objbine", java, false);这里的objbine是我们自己起的这个注册的名字实体，注意不能和java中特殊含义的文字重复例如external否则没有效果
webBrowser1.Document.InvokeScript("Messageaa",
objects);
在cefsharp中是通过注册来实现java与C#类的绑定的
JavaScripAction java = new JavaScripAction(dataSvc, bbShow, pdpcShowBb);
这样在javascrip中可以通过
window.objbine.InvokeFunc('0','1','cunction','1,2,3');
这种方式来调用C#类JavaScriptaction中的方法InvokFunc方法了，需要注意的是如果
在C#中调用JavaScript中的函数如下
web.ExecuteScriptAsync（string methodname,params object[] args）
需要注意的是如果JavaScript中的函数名是没有参数的这里的methodname需要在函数名后面加上括号的如果没有参数就不能加括号。
