Introduction to ASP.NET Web Pages

ASP.NET Web Pages is a lightweight, easy-to-learn web development framework that allows developers to build dynamic web applications in an easy way. This article will introduce the basic concepts, features and sample codes of ASP.NET Web Pages to help readers understand and start using this framework.

What are ASP.NET Web Pages

ASP.NET Web Pages is a development framework introduced by Microsoft for building web applications. It is based on ASP.NET technology and provides a lightweight, extensible way to create Web pages and handle user requests.

Compared with other ASP.NET frameworks such as ASP.NET MVC and ASP.NET Web Forms, ASP.NET Web Pages is more simple and easy to learn, suitable for small projects or beginners. It uses a view engine similar to Razor syntax, enabling developers to write dynamic Web pages using C# or VB.NET.

Features of ASP.NET Web Pages

ASP.NET Web Pages has the following main features:

1. Lightweight

ASP.NET Web Pages is a lightweight framework with relatively few core components and functions, making the development process easier and faster.

2. Razor syntax

ASP.NET Web Pages use the Razor syntax, which is a concise, readable view engine. Razor syntax allows developers to mix HTML and C# (or VB.NET) code in the same file, providing greater readability and maintainability.

Here's an example using Razor syntax:

<!DOCTYPE html>
<html>
<head>
    <title>ASP.NET Web Pages</title>
</head>
<body>
    <h1>Welcome to ASP.NET Web Pages</h1>

    <p>Current date and time: @DateTime.Now</p>
</body>
</html>

In the example above, @DateTime.Nowwill be replaced with the current date and time at runtime.

3. Simple page life cycle

ASP.NET Web Pages uses a simple page life cycle, and developers only need to pay attention to the process of loading pages and processing requests. It doesn't have complex lifecycle events and ViewState mechanism like ASP.NET Web Forms.

4. Built-in data access functions

ASP.NET Web Pages provides simple and powerful data access functions. It supports various data sources (such as databases, XML files, etc.) and provides some convenient APIs to perform common database operations.

Here's an example using the built-in data access functionality:

@{
    var db = Database.Open("MyDatabase");
    var products = db.Query("SELECT * FROM Products");
}

@foreach (var product in products) {
    <p>@product.Name - @product.Price</p>
}

In the example above, we Database.Openopened a database named "MyDatabase" via the method

The database connection and use db.Querythe method to execute a query, and then use the loop to output the query results to the page.

How to get started with ASP.NET Web Pages

To start using ASP.NET Web Pages, you need to follow these steps:

Install the .NET development tools and the ASP.NET Web Pages extension. You can download and install Visual Studio or Visual Studio Code from Microsoft's official website, and install the ASP.NET Web Pages extension through the extension manager.
Create a new ASP.NET Web Pages project. In Visual Studio, you can select the "ASP.NET Web Pages" template and follow the guidance of the wizard to complete the creation of the project.
Write and debug your web pages. Write your pages using Razor syntax and run and test them locally on a debug server.
Deploy your web application. Once you've finished developing and debugging, you can deploy the application to a web server to serve it externally.
