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"}]

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

Answer 1

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;
 }
