How to pass multiple model as parameter in WEB API - entity-framework

Question

Can anyone please help me to pass multiple models as a parameter to the request's content in WEB API?
I have 2 different Model Student and Employee
public class Student
{
public int StudentId { get; set; }
public string StudentName { get; set; }
public string Branch { get; set; }
}
public class Employee
{
public int EmployeeId { get; set; }
public string EmployeeName { get; set; }
public string Department { get; set; }
}
I have created an API and want to pass both these models as parameters in my action method InsertTestAPI.
[HttpPost]
[Route("TestAPI")]
public HttpResponseMessage InsertTestAPI(Student modelStudent, Employee modelEmployee)
{
// other logical operations
}
When I pass these models as JSON in the request body, I get the following error from Postman.
{
"$id": "1",
"Message": "An error has occurred.",
"ExceptionMessage": "Can't bind multiple parameters ('modelStudent' and 'modelEmployee') to the request's content.",
"ExceptionType": "System.InvalidOperationException",
"StackTrace": " at System.Web.Http.Controllers.HttpActionBinding.ExecuteBindingAsync(HttpActionContext actionContext, CancellationToken cancellationToken)\r\n at System.Web.Http.Controllers.ActionFilterResult.<ExecuteAsync>d__5.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()\r\n at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n at System.Web.Http.Dispatcher.HttpControllerDispatcher.<SendAsync>d__15.MoveNext()"
}
Can anyone please help me?

Answer 1

public class StudentEmployeModel
{
public Student Students{get;set;}
public Employee Employees{get;set;}
}
Create the StudentEmpendedModel class this way.
public HttpResponseMessage InsertTestAPI(StudentEmployeModel model)
{// other logical operations }
request this way
{ "students": { "studentId":"0", "studentName":"Mehmet", "branch":"software" } ,
"employees":
{"employeeId ":0,"employeeName":"Test","department":"IT"} }
This way you can send requests as Json

Answer 2

You can call Empolyee class in student class after that .then you can call multiple model call in api
public class Student
{
public int StudentId { get; set; }
public string StudentName { get; set; }
public string Branch { get; set; }
public Employee EmpData {get;set;}
}
