Introduction

ASP.NET is a popular language used for web applications. One common requirement in web development is to the current domain name of the website. In this article, we will explore ways to achieve this in ASP.NET, along with .

Using .Url

The Request.Url property provides information about the current URL being requested. To get the domain name, we can use the Host property of the Uri class.


string domainName = Request.Url.Host;

This will give us the domain name without the protocol (e.g., http:// or https://) and any path or query string.

Using HttpContext.Current.Request.Url

In some cases, the Request.Url property may not be accessible. In such scenarios, we can use the HttpContext.Current.Request.Url property to achieve the same result.


string domainName = HttpContext.Current.Request.Url.Host;

Using Request.ServerVariables

Another approach is to use the Request.ServerVariables collection, which provides access to various server variables, including the domain name.


string domainName = Request.ServerVariables["SERVER_NAME"];

This method is useful when the Request.Url property is not or when you need to access other server variables as well.
