Get Azure Web App name in code

Question

Is there any way to obtain the name of the web app from within code. i.e. if I have deployed my app to a web app called my-webapp-dev-ne I need to be able to get this name in code. The reason I cannot add it to an app config file or any other method is that the same app can be deployed to multiple places.

Adding to Rick's answer, you can find more informative environment settings here

• WEBSITE_SKU - The sku of the site (Possible values: Free, Shared, Basic, Standard).
• WEBSITE_COMPUTE_MODE - Specifies whether website is on a dedicated or shared VM/s (Possible values: Shared, Dedicated).
• WEBSITE_SITE_MODE - The mode for the site (can be Limited for a free site, Basic for a shared site or empty for a standard site).
• WEBSITE_HOSTNAME - The Azure Website's primary host name for the site (For example: site.azurewebsites.net). Note that custom hostnames are not accounted for here.
• WEBSITE_INSTANCE_ID - The id representing the VM that the site is running on (If site runs on multiple instances, each instance will have a different id).
• WEBSITE_NODE_DEFAULT_VERSION - The default node version this website is using.
• WEBSOCKET_CONCURRENT_REQUEST_LIMIT - The limit for websocket's concurrent requests.

Answer 2

The web app environment provides an environment variable called WEBSITE_SITE_NAME that contains the name. You can access it from C# code like this.

var siteName = Environment.GetEnvironmentVariable("WEBSITE_SITE_NAME");
