飞鸽传书，去看了下WEBBROWSER的资料

飞鸽传书，去看了下WEBBROWSER的资料，首先要建立一个桌面应用程序，然后拖一个webbrowser控件上去；接下来，就可以在后台添加相关代码。
首先我们还是把需要用到的控件加上去吧，喜欢的话，你也可以直接在设计界面拖进来。
加上控件之后我们顺便把要执行的事件都注册下。下面是代码：  处于工作需要，可以从通过输入的网站获得自己想要的数据了。

private MenuStrip menuStrip1;
        private ToolStripMenuItem fileToolStripMenuItem,
            saveAsToolStripMenuItem, printToolStripMenuItem,
            printPreviewToolStripMenuItem, exitToolStripMenuItem,
            pageSetupToolStripMenuItem, propertiesToolStripMenuItem;
        private ToolStripSeparator toolStripSeparator1, toolStripSeparator2;

        private ToolStrip toolStrip1, toolStrip2;// 飞鸽传书
        private ToolStripTextBox toolStripTextBox1;
        private ToolStripButton goButton, backButton,
            forwardButton, stopButton, refreshButton,
            homeButton, searchButton, printButton,sourceButton,formatButton;

        private StatusStrip statusStrip1;
        private ToolStripStatusLabel toolStripStatusLabel1;

        private void InitializeForm()

            printPreviewToolStripMenuItem = new ToolStripMenuItem();
            toolStripSeparator2 = new ToolStripSeparator();
            exitToolStripMenuItem = new ToolStripMenuItem();
            pageSetupToolStripMenuItem = new ToolStripMenuItem();
            propertiesToolStripMenuItem = new ToolStripMenuItem();

            toolStrip1 = new ToolStrip();
            goButton = new ToolStripButton();
            backButton = new ToolStripButton();
            forwardButton = new ToolStripButton();
            stopButton = new ToolStripButton();

            toolStrip2 = new ToolStrip();
            toolStripTextBox1 = new ToolStripTextBox();

            statusStrip1 = new StatusStrip();
            toolStripStatusLabel1 = new ToolStripStatusLabel();

            menuStrip1.Items.Add(fileToolStripMenuItem);

            fileToolStripMenuItem.DropDownItems.AddRange(
                new ToolStripItem[] {
                saveAsToolStripMenuItem, toolStripSeparator1,
                pageSetupToolStripMenuItem, printToolStripMenuItem,
                printPreviewToolStripMenuItem, toolStripSeparator2,
                propertiesToolStripMenuItem, exitToolStripMenuItem
            });

            fileToolStripMenuItem.Text = "&File";
            saveAsToolStripMenuItem.Text = "Save &As...";
            pageSetupToolStripMenuItem.Text = "Page Set&up...";
            printToolStripMenuItem.Text = "&Print...";
            printPreviewToolStripMenuItem.Text = "Print Pre&view...";
            propertiesToolStripMenuItem.Text = "Properties";
            exitToolStripMenuItem.Text = "E&xit";

            printToolStripMenuItem.ShortcutKeys = Keys.Control | Keys.P;

            saveAsToolStripMenuItem.Click +=
                new System.EventHandler(saveAsToolStripMenuItem_Click);
            pageSetupToolStripMenuItem.Click +=
                new System.EventHandler(pageSetupToolStripMenuItem_Click);
            printToolStripMenuItem.Click +=
                new System.EventHandler(printToolStripMenuItem_Click);
            printPreviewToolStripMenuItem.Click +=
                new System.EventHandler(printPreviewToolStripMenuItem_Click);
            propertiesToolStripMenuItem.Click +=
                new System.EventHandler(propertiesToolStripMenuItem_Click);
            exitToolStripMenuItem.Click +=
                new System.EventHandler(exitToolStripMenuItem_Click);

            toolStrip1.Items.AddRange(new ToolStripItem[] {
            goButton, backButton, forwardButton, stopButton,
            refreshButton, homeButton, searchButton, printButton,sourceButton,formatButton});

            goButton.Text = "Go";
            backButton.Text = "Back";
            forwardButton.Text = "Forward";
            stopButton.Text = "Stop";
            refreshButton.Text = "Refresh";
            homeButton.Text = "Home";
            searchButton.Text = "Search";
            printButton.Text = "Print";
            sourceButton.Text = "Source";
            formatButton.Text = "Format Source";

            backButton.Enabled = false;
            forwardButton.Enabled = false;

            goButton.Click += new System.EventHandler(goButton_Click);

            toolStrip2.Items.Add(toolStripTextBox1);

            Controls.AddRange(new Control[] {
            webBrowser1, toolStrip2, toolStrip1,
            menuStrip1, statusStrip1, menuStrip1 });
        }

然后我们来执行这些事件：

        // Displays the Save dialog box.
        private void saveAsToolStripMenuItem_Click(object sender, EventArgs e)
        {
            webBrowser1.ShowSaveAsDialog();
        }

        // Displays the Page Setup dialog box.
        private void pageSetupToolStripMenuItem_Click(object sender, EventArgs e)
        {
            webBrowser1.ShowPageSetupDialog();
        }

        // Displays the Print dialog box.
        private void printToolStripMenuItem_Click(object sender, EventArgs e)
        {
            webBrowser1.ShowPrintDialog();
        }

        // Displays the Print Preview dialog box.
        private void printPreviewToolStripMenuItem_Click(
            object sender, EventArgs e)
        {
            webBrowser1.ShowPrintPreviewDialog();
        }

        // Displays the Properties dialog box.
        private void propertiesToolStripMenuItem_Click(
            object sender, EventArgs e)
        {
            webBrowser1.ShowPropertiesDialog();
        }

        // Selects all the text in the text box when the user clicks it.
        private void toolStripTextBox1_Click(object sender, EventArgs e)
        {
            toolStripTextBox1.SelectAll();
        }

        // Navigates to the URL in the address box when
        // the ENTER key is pressed while the ToolStripTextBox has focus.
        private void toolStripTextBox1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
            {
                Navigate(toolStripTextBox1.Text);
            }
        }

        // Navigates to the URL in the address box when
        // the Go button is clicked.
        private void goButton_Click(object sender, EventArgs e)
        {
            Navigate(toolStripTextBox1.Text);
        }

        // Navigates to the given URL if it is valid.
        private void Navigate(String address)
        {
            if (String.IsNullOrEmpty(address)) return;
            if (address.Equals("about:blank")) return;
            if (!address.StartsWith("http://") &&
                !address.StartsWith("https://"))
            {
                address = "http://" + address;
            }
            try
            {
                webBrowser1.Navigate(new Uri(address));
            }
            catch (System.UriFormatException)
            {
                return;
            }
        }

        // Updates the URL in TextBoxAddress upon navigation.
        private void webBrowser1_Navigated(object sender,
            WebBrowserNavigatedEventArgs e)
        {
            toolStripTextBox1.Text = webBrowser1.Url.ToString();
        }

        // Navigates webBrowser1 to the previous page in the history.
        private void backButton_Click(object sender, EventArgs e)
        {
            webBrowser1.GoBack();
        }

        // Disables the Back button at the beginning of the navigation history.
        private void webBrowser1_CanGoBackChanged(object sender, EventArgs e)
        {
            backButton.Enabled = webBrowser1.CanGoBack;
        }

        // Navigates webBrowser1 to the next page in history.
        private void forwardButton_Click(object sender, EventArgs e)
        {
            webBrowser1.GoForward();
        }

        // Disables the Forward button at the end of navigation history.
        private void webBrowser1_CanGoForwardChanged(object sender, EventArgs e)
        {
            forwardButton.Enabled = webBrowser1.CanGoForward;
        }

        // Halts the current navigation and any sounds or animations on
        // the page.
        private void stopButton_Click(object sender, EventArgs e)
        {
            webBrowser1.Stop();
        }

        // Reloads the current page.
        private void refreshButton_Click(object sender, EventArgs e)
        {
            // Skip refresh if about:blank is loaded to avoid removing
            // content specified by the DocumentText property.
            if (!webBrowser1.Url.Equals("about:blank"))
            {
                webBrowser1.Refresh();
            }
        }

        // Navigates webBrowser1 to the home page of the current user.
        private void homeButton_Click(object sender, EventArgs e)
        {
            webBrowser1.GoHome();
        }

        // Navigates webBrowser1 to the search page of the current user.
        private void searchButton_Click(object sender, EventArgs e)
        {
            webBrowser1.GoSearch();
        }

        // Prints the current document using the current print settings.
        private void printButton_Click(object sender, EventArgs e)
        {
            webBrowser1.Print();
        }

        // Updates the status bar with the current browser status text.
        private void webBrowser1_StatusTextChanged(object sender, EventArgs e)
        {
            toolStripStatusLabel1.Text = webBrowser1.StatusText;
        }

        // Updates the title bar with the current document title.
        private void webBrowser1_DocumentTitleChanged(object sender, EventArgs e)
        {
            this.Text = webBrowser1.DocumentTitle;
        }

        // Exits the application.
        private void exitToolStripMenuItem_Click(object sender, EventArgs e)
        {
            Application.Exit();
        }

其实我们现在就可以通过该控件浏览网页
