有时候浏览到非常有用的网页时，我们会选择将它加入到收藏夹中，但是网站一旦过期，以后就看不到这个网页了。当然也可以将网页打印成PDF文档保存。最新的Windows 10中的Edge浏览器支持将网页保存至OneNote中，但在OneNote中其实是保存了一张当前页面的完整图片。这篇博客将介绍如何使用C#将完整的页面保存成图片。
使用WinForms中的WebBrowser来保存图片，具体DrawToBitmap方法进行保存。新建一个Console程序(添加System.Windows.Forms)，
[STAThread] static void Main(string[] args) { int width = 800; int height = 600;using (WebBrowser browser = new WebBrowser()) { browser.Width = width; browser.Height = height; browser.ScrollBarsEnabled = false; browser.ScriptErrorsSuppressed = true; browser.DocumentCompleted += OnDocumentCompleted; browser.Navigate("http://www.cnblogs.com"); Application.Run(); } } private static void OnDocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { WebBrowser browser = (WebBrowser)sender; using (Graphics graphics = browser.CreateGraphics()) { int dWidth = browser.Document.Body.ScrollRectangle.Width; int dHeight = browser.Document.Body.ScrollRectangle.Height; browser.Height = dHeight; browser.Width = dWidth; using (Bitmap bitmap = new Bitmap(dWidth, dHeight, graphics)) { Rectangle bounds = new Rectangle(0, 0, dWidth, dHeight); browser.DrawToBitmap(bitmap, bounds); bitmap.Save("Screenshot1.png", ImageFormat.Png); } } Application.Exit(); }
注意加粗的代码，当页面加载完成后，需要根据网页的大小来调整WebBrowser的大小，否则保存的页面大小就是初始时给WebBrowser设置的大小。
上述代码中，直接将需要截图的页面写在代码中，如果能够直接读取当前IE/FireFox/Chrome打开的页面，直接截图就完美了。
增加获取当前IE/FireFox/Chrome打开的页面，
代码参考自：https://stackoverflow.com/questions/5317642/retrieve-current-url-from-c-sharp-windows-forms-application
添加UIAutomationClient和UIAutomationTypes引用，
public static string GetChromeUrl(Process process) { if (process == null) throw new ArgumentNullException("process"); if (process.MainWindowHandle == IntPtr.Zero) return null; AutomationElement element = AutomationElement.FromHandle(process.MainWindowHandle); if (element == null) return null; AutomationElement edit = element.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit)); return ((ValuePattern)edit.GetCurrentPattern(ValuePattern.Pattern)).Current.Value as string; } public static string GetInternetExplorerUrl(Process process) { if (process == null) throw new ArgumentNullException("process"); if (process.MainWindowHandle == IntPtr.Zero) return null; AutomationElement element = AutomationElement.FromHandle(process.MainWindowHandle); if (element == null) return null; AutomationElement rebar = element.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ClassNameProperty, "ReBarWindow32")); if (rebar == null) return null; AutomationElement edit = rebar.FindFirst(TreeScope.Subtree, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit)); return ((ValuePattern)edit.GetCurrentPattern(ValuePattern.Pattern)).Current.Value as string; } public static string GetFirefoxUrl(Process process) { if (process == null) throw new ArgumentNullException("process"); if (process.MainWindowHandle == IntPtr.Zero) return null; AutomationElement element = AutomationElement.FromHandle(process.MainWindowHandle); if (element == null) return null; AutomationElement doc = element.FindFirst(TreeScope.Subtree, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document)); if (doc == null) return null; return ((ValuePattern)doc.GetCurrentPattern(ValuePattern.Pattern)).Current.Value as string; }
根据浏览器进程查找当前Active的页面，
string url = string.Empty; foreach (Process process in Process.GetProcessesByName("firefox")) { url = GetFirefoxUrl(process); if (url != null) { // Find the target Url break; } } foreach (Process process in Process.GetProcessesByName("iexplore")) { url = GetInternetExplorerUrl(process); if (url != null) { // Find the target Url break; } } foreach (Process process in Process.GetProcessesByName("chrome")) { url = GetChromeUrl(process); if (url != null) { // Find the target Url break; } }
此时就不需要手动的修改需要截图的Url地址了，直接一键截图~
