Return array object in asp.net WebAPI

Question

I want to create WEB API which sends input to Angular. I want to send data in JSON format as an array.

Below is my code:

[HttpGet]
[ActionName("GetEmployeeByID")]
public Employee Get(int id)
{
    Employee emp = null;
    while (reader.Read())
    {
        emp = new Employee();
        emp.ClientId = Convert.ToInt32(reader.GetValue(0));
        emp.ClientName = reader.GetValue(1).ToString();
    }
    return emp;
}

Actual output:

{"ClientId":15,"ClientName":"Abhinav Singh"}

Expected output:

[{"ClientId":15,"ClientName":"Abhinav Singh"}]

you are returning a single object. Send a list of employees and add that employee to the list. — It's a trap

The actual output is correct if you should stick with the rest principles. If you ask for a user by Id, you don't expect to get a list in return.. — Marcus Höglund

Your code return only a single element. Change it to return a collection by using List as follows,

  public List<Employee> Get(int id)
    {
        Employee emp = null;
        List<Employee> _employees = new List<Employee>();
        while (reader.Read())
        {
            emp = new Employee();
            emp.ClientId = Convert.ToInt32(reader.GetValue(0));
            emp.ClientName = reader.GetValue(1).ToString();
            _employees.Add(emp);
        }
        return _employees;
     }
