How to use implicit and explicit operators in C#

Developers who know ASP.NET can leverage their existing knowledge of C# and can quickly pick up the framework differences introduced in ASP.NET Core. ASP.NET is an open source, server-side web application framework created by Microsoft that runs on Windows and was started in the early 2000s. ASP.NET allows developers to create web applications, web services, and dynamic content-driven websites. Take advantage of implicit and explicit operators to convert between user-defined types and improve the readability of your code.

Examples might be simplified to improve reading and learning. Tutorials, references, and examples are constantly reviewed to avoid errors, but we cannot warrant full correctness of all content. While using W3Schools, you agree to have read and accepted our terms of use,cookie and privacy policy. ~/ in most cases resolves to the web root of any website right right after the domain, no matter what page or subfolder you are in when the path is called. So the two are the same in MOST cases unless you set up a Virtual Application on the server.

ASP.NET applications are compiled, which means the code is translated into object code, which is then executed. This compilation process takes a small amount of time, but happens only once. After compilation, the code can be executed over and over by the .Net platform very quickly. These applications offer improved efficiency by taking advantage of early linking, just-in-time compilation, native optimization, and caching services straight out of the box. ASP.NET is a web framework designed by Microsoft Inc. that is extensively used to build robust web applications.

  • This gives the websites a lot of strength and versatility.
  • This type of type casting is known as explicit type casting because you must write explicit code to perform the type casting.
  • In this case you’ll need an explicit cast to convert an Author instance to an AuthorDto instance as shown in the code snippet given below.
  • If you do, that should be managed on the server side and injected into your HTML and JavaScript, not the other way around.
  • Interpreted languages would not identify this error until the code is actually run and tested.
  • If you need to write such conversion code for several classes in your application, you will not only find it cumbersome but also your code will not have proper readability.
  • Click Update next to Website preferences.The Website Payment Preferences screen appears.

The tilde refers to the application root directory, and will be translated correctly in control properties such as NavigateUrl. @JamieKitson If you do that, it will only work if the path is correct relative to the user’s current location on the site. Don’t do that either because it will only work if you deploy your web-app to the root of the domain (e.g. ). It won’t work though if you deploy to a sub-dir (e.g. /MyAppRoot). It is always best to ensure you use app-root-relative URLs (the ones with the ~) to ensure your web-app is portable.

Printing in C# Made Easy

Microsoft .NET is now using ~/ in Routing Attribute paths. When used they start the path back at the web root as an absolute path, but also override all controller or other attribute paths. ~/ is a character that tells ASP.NET on the IIs Windows Server to find the “application root” of your website.

This article talks about these explicit and implicit conversion operators and how we can work with them in C#. To work with the code examples provided in asp net usage this article, you should have Visual Studio 2022 installed in your system. If you don’t already have a copy, you can download Visual Studio 2022 here.

If you have defined an implicit operator, you will be able to convert objects both implicitly and explicitly. However, if you have defined an explicit operator, you will be able to convert objects explicitly only. This explains why you cannot have both implicit and explicit operators in a class. Although an implicit cast is more convenient to use, an explicit cast provides better clarity and readability of your code. The following code snippet shows how you can take advantage of the explicit operator to convert an Author instance to an instance of AuthorDto class. The following code snippet shows how you can take advantage of the implicit operator to convert an Author instance to an AuthorDto instance.

Character Sets

In the world of web and application development, there are many frameworks and languages that developers can choose from. Each framework has features and benefits that make them different. The framework I will be discussing in this blog post is ASP.NET and ASP.NET Core. Here’s the error you’ll observe In Visual Studio on compilation of the above code snippet. This tutorial covers all the basic elements of ASP.NET that a beginner would require to get started. The most recent framework of ASP.NET is ASP.NET core which is an open-source, cross-platform, and cloud-based internet-connected web application.

At Embarc, a leading builder of web presences for biotech companies, Matt rose from developer to Director of Technology and board member. He went on to build and run, winner of PC Magazine Editor’s Choice for wiki services, which was acquired by Wakefly in 2011. At Wakefly, Matt upholds a process-driven standard of excellence to deliver exceptional quality and value. Websites and applications built with ASP.NET can be faster and more efficient than a website build with PHP, for example.

These applications are language-independent, so it allows you to select the language that is best for you. These applications have windows authentication which makes the applications more secure. ASP.NET framework reduces higher costs along with creating custom web applications with all features.

It allows you to use a full featured programming language such as C# or VB.NET to build web applications easily. In addition to an IDE, websites require web application server software and a hosting server. IIS is available for all versions of Microsoft Windows at no additional cost. Windows hosting servers are usually more expensive than comparable Linux servers, which are commonly used to run PHP, JavaScript and Ruby applications. However, with the release of ASP.NET Core in 2016, ASP.NET applications are no longer reliant on IIS and can now be hosted on Linux and MacOS as well as Windows.

In the old days, we used to create Virtual Applications in IIs Web Server to create two more web paths in order to isolate one or more web ‘experiences’ using the same domain. Each Virtual Path might be a “ghost” path that points back to the web root but creates an additional ghost folder under the web root. In many cases, that new virtual path pointed to a physical folder separate from the normal web path or even to computer hard drive path or mapping. ASP.NET with the right permission then ran web site code from there.


Interpreted code is not directly executed by the machine, but must be read and interpreted each time before being executed. Compiled code is usually faster and more scalable than interpreted code, and can do anything interpreted code can do. Examples of interpreted languages include PHP, JavaScript and Ruby. Lesser code encourages the application to easily manage and effectively maintain.

ASP was introduced in 1998 as Microsoft’s first server side scripting language. When a browser requests an ASP or ASP.NET file, the ASP engine reads the file, executes any code in the file, and returns the result to the browser. Both technologies enable computer code to be executed by an Internet server. Wakefly is looking for an experienced Web Developer to join our team.

When your public certificate is successfully uploaded, it appears on the next screen under Your Public Certificate. This will generate your public certificate file; in this example, the filename is test-pubcert.pem. This will create your private key file; in this example, the filename is test-prvkey.pem. This will be used to display all movie related components.

Finally, even though ASP.NET is open source and free to use, it is actively developed and supported by the world’s largest software company, Microsoft. Microsoft is heavily invested in their development platforms, their developer community, and supporting the software companies use to run these applications. This means you don’t need to worry about your software becoming yesterday’s news any time soon.

ASP.NET framework has led to the rising of Microsoft app development. The following two methods show how you can convert an Author instance to an AuthorDto instance and convert and AuthorDto instance to an Author instance. The above code will compile successfully without any errors. In the “Additional information” window shown next, choose “.NET 7.0 ” as the framework version you want to use.
