How do I import a namespace in Razor View Page?

💻 Importing a Namespace in Razor View Pages: A Complete Guide

So, you're working on a Razor View Page and you need to import a namespace. But you're not quite sure how to do it. Don't worry, my friend! I've got your back! 😎

Common Issues and Solutions

Issue 1: Missing Namespace

Problem: You're trying to use a class or a helper method from a namespace, but it's not recognized in your Razor View Page.

Solution: To import a namespace in a Razor View Page, you need to use the @using directive. Simply add the following line at the beginning of your Razor View Page:

@using NamespaceName

Replace NamespaceName with the actual namespace you want to import. For example, if you want to import the System.Text namespace, you can do:

@using System.Text

Issue 2: Multiple Namespaces

Problem: You need to import multiple namespaces in your Razor View Page, but you're not sure how to do it efficiently.

Solution: You can import multiple namespaces by using multiple @using directives. Each @using directive should be on a separate line. For example:

@using Namespace1
@using Namespace2
@using Namespace3

Don't forget to replace Namespace1, Namespace2, and Namespace3 with the desired namespaces.

Example

Let's say you have a Razor View Page where you want to use the HtmlHelper class from the System.Web.Mvc namespace, and the UrlEncoder class from the System.Text.Encodings.Web namespace. Your Razor View Page might look something like this:

@using System.Web.Mvc
@using System.Text.Encodings.Web

<!-- Your HTML code goes here -->

@{
    // Your C# code goes here
    var encodedUrl = UrlEncoder.Default.Encode("https://example.com");
}

<!-- More HTML code -->

<p>Encoded URL: @encodedUrl</p>

In the example above, we import the necessary namespaces using the @using directive, and then we're able to use the HtmlHelper class and the UrlEncoder class in our Razor View Page.
