ASP.NET Web Pages - Global Pages

In ASP.NET Web Pages development, the global page (Global Page) is an important concept. Global pages allow you to share code and data application-wide to improve development efficiency and maintain consistency. This blog will introduce in detail how to use global pages in ASP.NET Web Pages, and provide examples and codes.

What are global pages?

A global page is a special page that contains code and data that is shared among multiple pages in the application. By placing shared code and data in global pages, you can avoid duplicating the same code in every page and ensure consistency and maintainability.

Create a global page

In ASP.NET Web Pages, creating global pages is very simple. Here are the basic steps to create a global page:

Create a new page in the project folder named _AppStart.cshtml.
Write shared code and data in _AppStart.cshtmlpages .

For example, here is an example of a simple _AppStart.cshtmlglobal page:

@{
    // 全局代码和数据
    var siteName = "我的网站";
    var currentDate = DateTime.Now;
}

<!DOCTYPE html>
<html>
<head>
    <title>@siteName</title>
</head>
<body>
    <div id="header">
        <h1>@siteName</h1>
        <p>当前时间：@currentDate</p>
    </div>

    <div id="content">
        @RenderBody()
    </div>

    <div id="footer">
        <p>版权所有 &copy; @currentDate.Year - @siteName</p>
    </div>
</body>
</html>

In the example above, _AppStart.cshtmlwe defined siteNameand currentDatevariables in the page, which are available throughout the application. At the same time, we use @RenderBody()the method to insert the content of the subpage.

Use global pages

Using global pages is very simple. Just inherit the global page in other pages. Here are the basic steps to use global pages:

In other pages, use to @{ Layout = "~/Shared/_AppStart.cshtml"; }specify a global page.
Write specific content for the page.

For example, here's an example using global pages:

@{
    Layout = "~/Shared/_AppStart.cshtml";
}

<h2>欢迎来到我的网站！</h2>
<p>这是一个使用 ASP.NET Web Pages 创建的网站。</p>

In the example above, we used @{}the code block to specify the global page to use. We can then write our own specific content in the page.

Advantages of Global Pages

There are several advantages to using global pages:

Code reuse : By placing shared code in global pages, you can avoid having to

Repeatedly write the same code to improve development efficiency.
2. Consistency : Global pages ensure consistency throughout the application, giving pages the same layout and style.
3. Easy to maintain : Centrally place the shared code in the global page, making it more convenient to modify and maintain the code.

Summarize

Global pages are a powerful and useful concept in ASP.NET Web Pages development. By judicious use of global pages, you can share code and data across your application, improving development efficiency and maintaining consistency. The advantages brought by global pages include code reuse, consistency, and ease of maintenance.

I hope this blog will help you understand the use of global pages in ASP.NET Web Pages.
