一、原理

主要通过WebBrowser加载html文件，实现支持markdown语法的功能

二、主要步骤

1.创建Form窗体

2.添加WebBrowser到窗体中

3.加载html文件

public Markdown()
    {
        InitializeComponent();
        Form1_Load();
    }

            private void Form1_Load()
    {
        VersionClass.SetIE(VersionClass.IeVersion.强制ie9);
        webBrowser1.ScriptErrorsSuppressed = true; //禁用错误脚本提示  
        webBrowser1.IsWebBrowserContextMenuEnabled = true; // 禁用右键菜单  
        webBrowser1.WebBrowserShortcutsEnabled = true; //禁用快捷键  
        webBrowser1.AllowWebBrowserDrop = false; // 禁止文件拖动  
        webBrowser1.Navigate(Application.StartupPath + Path.DirectorySeparatorChar + "editormd" + Path.DirectorySeparatorChar +"simple.html");
        webBrowser1.Navigated += WebBrowserNavigatedEventHandler;
        webBrowser1.DocumentCompleted += WebBrowserDocumentCompletedEventHandler;
        //webBrowser1.Document.Window.Error += new HtmlElementErrorEventHandler(Window_Error);
        webBrowser1.NewWindow += CancelEventHandler;
    }
    //禁用新窗口打开  
    public void CancelEventHandler(object sender, CancelEventArgs e)
    {
        e.Cancel = true;
    }

    private void Window_Error(object sender, HtmlElementErrorEventArgs e)
    {
        e.Handled = true;
    }

    //后发生  
    public void WebBrowserDocumentCompletedEventHandler(object sender, WebBrowserDocumentCompletedEventArgs e)
    {

    }
    //先发生  
    public void WebBrowserNavigatedEventHandler(object sender, WebBrowserNavigatedEventArgs e)
    {

    }
