Sorting Data with Ascending & Decending Order ASP.NET Core 7.0

Asscending:

        // GET: api/Coffee
        [HttpGet]
        public IActionResult GetAll()

        {
            try
            {
                var coffees = _coffeeManager.GetAll();
                return Ok(coffees);
            }
            catch (Exception ex)
            {
                return BadRequest(ex.Message);
            }
            
        }

Above this method i tried to get list of Data array where it return data by default Ascending Order. We also can create functionality for return ascending order data same as below code:

        // GET: api/Coffee
        [HttpGet]
        public IActionResult GetAll()

        {
            try
            {
                var coffees = _coffeeManager.GetAll().OrderBy(u=>u.CreatedDate);
                return Ok(coffees);
            }
            catch (Exception ex)
            {
                return BadRequest(ex.Message);
            }
            
        }

Here, i created ascending order by CreatedDate. We also can use others properties for doing ascending order.

Output:

[
  {
    \"id\": 1,
    \"title\": \"new string\",
    \"description\": \"new description string\",
    \"createdDate\": \"2023-06-21T01:56:41.971\"
  },
  {
    \"id\": 2,
    \"title\": \"string 2\",
    \"description\": \"string 2\",
    \"createdDate\": \"2023-06-24T07:24:40.814567\"
  },
  {
    \"id\": 3,
    \"title\": \"string 3\",
    \"description\": \"string 3\",
    \"createdDate\": \"2023-06-24T07:24:48.008345\"
  },
  {
    \"id\": 4,
    \"title\": \"string 4\",
    \"description\": \"string 4\",
    \"createdDate\": \"2023-06-24T07:24:53.902131\"
  },
  {
    \"id\": 5,
    \"title\": \"string 5\",
    \"description\": \"string 5\",
    \"createdDate\": \"2023-06-24T07:25:05.55175\"
  },
  {
    \"id\": 6,
    \"title\": \"string 6\",
    \"description\": \"string 6\",
    \"createdDate\": \"2023-06-24T07:25:27.125118\"
  }
]

Decending:

        // GET: api/Coffee
        [HttpGet]
        public IActionResult GetAllOrderByDecending()

        {
            try
            {
                var coffees = _coffeeManager.GetAll().OrderByDescending(u=>u.CreatedDate);
                return Ok(coffees);
            }
            catch (Exception ex)
            {
                return BadRequest(ex.Message);
            }

        }

It's same as ascending order. Only changed method name OrderByDescending. It will return us decending order data.

Output:

[
  {
    \"id\": 6,
    \"title\": \"string 6\",
    \"description\": \"string 6\",
    \"createdDate\": \"2023-06-24T07:25:27.125118\"
  },
  {
    \"id\": 5,
    \"title\": \"string 5\",
    \"description\": \"string 5\",
    \"createdDate\": \"2023-06-24T07:25:05.55175\"
  },
  {
    \"id\": 4,
    \"title\": \"string 4\",
    \"description\": \"string 4\",
    \"createdDate\": \"2023-06-24T07:24:53.902131\"
  },
  {
    \"id\": 3,
    \"title\": \"string 3\",
    \"description\": \"string 3\",
    \"createdDate\": \"2023-06-24T07:24:48.008345\"
  },
  {
    \"id\": 2,
    \"title\": \"string 2\",
    \"description\": \"string 2\",
    \"createdDate\": \"2023-06-24T07:24:40.814567\"
  },
  {
    \"id\": 1,
    \"title\": \"new string\",
    \"description\": \"new description string\",
    \"createdDate\": \"2023-06-21T01:56:41.971\"
  }
]

Multiple Condition:

       // GET: api/Coffee
        [HttpGet]
        public IActionResult GetAllOrderByDesc()
        {
            try
            {
                var coffees = _coffeeManager.GetAll().OrderByDescending(u => u.CreatedDate).ThenByDescending(u=>u.Title);
                return Ok(coffees);
            }
            catch (Exception ex)
            {
                return BadRequest(ex.Message);
            }

        }
