What is the method executed by C# WebAPI?

In C# WebAPI, methods are typically triggered by HTTP requests and can be of the following types:

1. Use the GET method to retrieve resources, and filter and sort them by passing parameters through the URL.
2. POST: This method is used to create a resource by sending parameters in the request body to add data.
3. PUT is used to update a resource by passing new data through URL parameters and request body.
4. DELETE: Used to remove resources by passing parameters through the URL for deletion.

These methods correspond to different operations in WebAPI, where you can define different methods in the controller to handle different requests. For example, you can use attributes such as HttpGet, HttpPost, HttpPut, and HttpDelete to define the corresponding methods.
