Get IIS Web Site Application Name in C#

Get IIS Web Site Application Name in C#

To get the name of an IIS web site application in C#, you can use the ServerVariables property of the HttpRequest object, which contains a collection of server variables, including the APPL_MD_PATH variable that contains the application name.

Here's an example of how to get the application name in an ASP.NET MVC controller action:

public ActionResult MyAction() { string applicationName = Request.ServerVariables["APPL_MD_PATH"]; int index = applicationName.LastIndexOf('/'); if (index >= 0) { applicationName = applicationName.Substring(index + 1); } return View(applicationName); }

In this example, we get the value of the APPL_MD_PATH variable from the ServerVariables collection of the HttpRequest object. We then extract the name of the application from the variable by finding the last occurrence of the '/' character and taking the substring after it. We then pass the application name as a parameter to the View method.

Note that the APPL_MD_PATH variable contains the path of the application in the format /LM/W3SVC/{site ID}/ROOT/{application path}, where {site ID} is the ID of the IIS web site and {application path} is the path of the application within the web site. By extracting the substring after the last '/' character, we get the name of the application.
