The more difficult point in this video is Web Pages:
Three programming models Web Pages, Web Forms and MVC (Model, View, Controller)
Web Pages is the simplest ASP .NET web development programming model. It provides a simple way to combine HTML, CSS, JavaScript and server code:
Easy to learn, read and use
Build around a single web page
Similar to PHP and ASP
Server Scripting using Visual Basic or C
#Full control over HTML, CSS, JavaScript
Web Pages are extended with programmable Web Helpers to include databases, videos, Images, social networks and more.
A Razor web page can be described as an HTML page with two kinds of content: HTML content and Razor code.
When the server reads this kind of page, it will first run the Razor code before sending the HTML page to the browser. These codes executed on the server can complete tasks that cannot be completed in the browser, such as accessing the server database. Server code can create dynamic HTML content before the page is sent to the browser. From a browser perspective, there is no difference between HTML generated by server code and static HTML content.
Layout (such as header and footer).
With Web Pages, you can use the @RenderPage() method to import content from different files.
<html>
<body>
@RenderPage("header.cshtml")
<h1 id="Hello-nbsp-Web-nbsp-Pages">Hello Web Pages</h1>
<p>This is a paragraph</p>
@RenderPage("footer.cshtml")
</body>
</html>Using the layout page The layout page is similar to an ordinary web page, but the @RenderBody() method will be called at the location of the referenced content page. Every content page must begin with a Layout directive. This is the code: Layout web page:
<html> <body> <p>This is header text</p> @RenderBody() <p>© 2012 W3School. All rights reserved.</p> </body> </html>
Any web page:
@{Layout="Layout.cshtml";}
<h1 id="Welcome-nbsp-to-nbsp-W-Schools">Welcome to W3Schools</h1>
<p>
Lorem ipsum dolor sit amet, consectetur adipisicing elit,sed do eiusmod tempor
incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud
exercitation ullamco laborisnisi ut aliquip ex ea commodo consequat.
</p>ASP.NET provides three tools for processing folder paths: ~ operator, Server.MapPath method as well as the Href method.
~ Operator
To specify the virtual root directory in programming code, use the ~ operator.
If you use the ~ operator instead of a path, you can move the website to a different folder or location without changing any code:
var myImagesFolder = "~/images"; var myStyleSheet = "~/styles/StyleSheet.css";
Server.MapPath method
The Server.MapPath method converts the virtual path (/default.cshtml) to a physical path that the server can understand (C:\Johnny\MyWebSited\Demo\default.cshtml).
You will use this method when you need to open a data file located on the server (the data file can only be accessed through the complete physical path):
var pathName = "~/dataFile.txt"; var fileName = Server.MapPath(pathName);

In summer, you must try shooting a rainbow
Jul 21, 2024 pm 05:16 PM
After rain in summer, you can often see a beautiful and magical special weather scene - rainbow. This is also a rare scene that can be encountered in photography, and it is very photogenic. There are several conditions for a rainbow to appear: first, there are enough water droplets in the air, and second, the sun shines at a low angle. Therefore, it is easiest to see a rainbow in the afternoon after the rain has cleared up. However, the formation of a rainbow is greatly affected by weather, light and other conditions, so it generally only lasts for a short period of time, and the best viewing and shooting time is even shorter. So when you encounter a rainbow, how can you properly record it and photograph it with quality? 1. Look for rainbows. In addition to the conditions mentioned above, rainbows usually appear in the direction of sunlight, that is, if the sun shines from west to east, rainbows are more likely to appear in the east.
