In C#, What Is The Syntax For Passing Multiple Parameters To A Get Method In ASP.NET Core?

In ASP.NET Core, you can pass multiple parameters to a GET method by including them in the URL of the HTTP request or by using model binding.

  1. Passing Parameters in the URL:

    • Define the parameters in the route template of your GET method in the controller. For example:
      [HttpGet("api/users/{id}/orders/{orderId}")]
      public IActionResult GetOrder(int id, int orderId)
      {
          // your code here
      }
      
    • The parameters (id and orderId in this example) will be extracted from the URL when the GET request is made. For example: GET /api/users/1/orders/123.
  2. Using Model Binding:

    • Define a model class that represents the parameters you want to pass. For example:
      public class OrderRequestModel
      {
          public int UserId { get; set; }
          public int OrderId { get; set; }
      }
      
    • Use the model class as a parameter in your GET method. For example:
      [HttpGet("api/orders")]
      public IActionResult GetOrder([FromQuery] OrderRequestModel request)
      {
          // your code here
      }
      
    • The parameters will be extracted from the query string of the URL when the GET request is made. For example: GET /api/orders?userId=1&orderId=123.

You can choose the approach that suits your requirements best.
