C# - 了解控制台应用程序中 HTML 内容的高度 [英] C# - Know the height of HTML content in a console application
问题描述
我有类似的 HTML 代码 -
I have HTML code something like -
<html>
<body>
<table><tr><td><h1>Heading</h1></td></tr></table>
</body>
</html>
在一个特定的需求中，我需要提前知道这个 HTML 需要多少高度才能全屏显示.以便我保留专门为该内容计算的空间.
In a specific requirement, I need to know in advance that how much height will this HTML will take to display in fullscreen. So that I keep that much space calculated specifically for that content.
我的想法是在WebBrowser控件中渲染这段代码，然后取高度.
What I thought was to render this code in WebBrowser control, and then take the height.
this.webBrowser1.Url = new Uri(htmlFilePath);
//The below code will force the webbrowser control to load the HTML in it.
while (this.webBrowser1.Document.Body == null)
{
Application.DoEvents();
}
int height = this.webBrowser1.Document.Body.ScrollRectangle.Height;
但在控制台应用程序中，我无法使用 WebBrowser 控件.我还有其他方法可以做到这一点吗?
But in console application I can't use WebBrowser control. Is there any other way I can accomplish this?
推荐答案
回答我自己的问题 -
Answering my own question -
我需要做的就是在我的控制台应用程序中添加对 System.Windows.Forms 的引用.之后，我可以直接在无头表单中使用 WebBrowser，而无需创建任何表单元素.
All I needed to do was adding reference of System.Windows.Forms in my console application.
After that I was able to use WebBrowser in headless form directly without creating any form element.
使用 WebBrowser 后，我设置了合理数字的高度/宽度.像下面这样 -
After using WebBrowser, I set the height/width of reasonable number. Something like below -
WebBrowser wb = new WebBrowser();
//Setting the page height and width to a reasonable number. So that whatever the content loaded in it gets aligned properly.
//For me 3000 works fine for my requirements.
wb.Width = 3000;
wb.Height = 3000;
wb.Url = new Uri(htmlFilePath);
//the below code will force the webbrowser control to load the html in it.
while (wb.Document.Body == null)
{
Application.DoEvents();
}
int height = wb.Document.Body.ScrollRectangle.Height;
