c# - 使用 mshtml 和 shdocview vb.net/C# 捕获 Web 元素

Question

我想设计一个 WPF 页面，我们可以在其中捕获网页屏幕元素。这应该类似于 IE F12(DOM Explorer) 选择元素选项。任何人都可以建议从哪里开始。提前致谢

Answer 1

您可以为此使用 selenium，安装后您可以通过以下方式实现：

driver.get("http://www.google.com");
WebElement element = driver.findElement(By.id("hplogo"));

// Get entire page screenshot
File screenshot = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
BufferedImage fullImg = ImageIO.read(screenshot);

// Get the location of element on the page
Point point = element.getLocation();

// Get width and height of the element
int eleWidth = element.getSize().getWidth();
int eleHeight = element.getSize().getHeight();

// Crop the entire page screenshot to get only element screenshot
BufferedImage eleScreenshot= fullImg.getSubimage(point.getX(), point.getY(),
    eleWidth, eleHeight);
ImageIO.write(eleScreenshot, "png", screenshot);

// Copy the element screenshot to disk
File screenshotLocation = new File(@"C:\GoogleLogo.png");
FileUtils.copyFile(screenshot, screenshotLocation);
