Question

我在C＃应用程序中使用WebKit来呈现CSS样式的XML文档，我希望能够添加DOM元素。如何访问DOM才能执行此操作？问题似乎是WebKitBrowser类中没有属性可以访问私有webView成员。可能吗？我是否需要修改类才能添加此项？我只是做错吗？

从0.3.0开始，WebKit.Net似乎无法访问encodeom。我做了一些稍微不同的事情，我使用了WebKit.Net，但我在应用程序中添加了一个HTTP侦听器，并设置了控件以从那里检索页面。通过这种方式，我可以访问同一个应用程序中的帖子和回调。其余的我自己在页面上使用JavaScript。

        HttpListener listener;

    public Form1( ) {
        InitializeComponent( );

        listener = new System.Net.HttpListener( );

        listener.Prefixes.Add( "http://*:88/" );
        listener.Start( );
        IAsyncResult result = listener.BeginGetContext( new AsyncCallback(  ListenerCallback ), listener );

    }

    public static void ListenerCallback( IAsyncResult result ) {

    string resp = "<body>test</body";

        HttpListener listener = ( HttpListener )result.AsyncState;

        // Call EndGetContext to complete the asynchronous operation.
        try {
            HttpListenerContext context = listener.EndGetContext( result );
            HttpListenerRequest request = context.Request;

            // Obtain a response object.
            HttpListenerResponse response = context.Response;

            // Construct a response.
            string webpage = request.Url.AbsolutePath.Substring( 1 );
            string responseString = null;
            if ( string.IsNullOrEmpty( webpage ) ) {
                responseString = resp;
            }
            else {
                webpage = webpage.Replace( ".", "_" );
                responseString = webkit_test.Properties.Resources.ResourceManager.GetResourceSet( System.Globalization.CultureInfo.CurrentCulture, true, false ).GetObject( webpage ) as string;
                if ( responseString == null ) {
                    responseString = "<html></html><body> 404 Web Page not Found</body>";
                }
            }
            byte[ ] buffer = System.Text.Encoding.UTF8.GetBytes( responseString );

            // Get a response stream and write the response to it.
            response.ContentType = "text/html; charset=UTF-8";
            response.ContentLength64 = buffer.Length;

            System.IO.Stream output = response.OutputStream;
            output.Write( buffer, 0, buffer.Length );
            output.Flush( );

            // You must close the output stream.
            output.Close( );
            IAsyncResult result1 = listener.BeginGetContext( new AsyncCallback( ListenerCallback ), listener );
        }
        catch { }
    }

顺便说一下。该代码还将从嵌入资源中读取网页
