can i declare variable in controller scope in MVC 5

Niraj Singh

Hello All,

Can i declare a variable in controller scope in Asp.net Mvc5 application or not?

For Example:

public class EmloyeeController : Controller

{

private readonly IEmployee _employee;

public EmployeeController(IEmployee emp){

{

_employee=emp;

}

this line gives error that "Method must have return type" where I have declare a private variable of type IEmployee.

Yes, we can declare but we need to implement Dependency Injection otherwise will get "No parameterless constructor defined for this object.", please find below links for reference.

It seens to currect .Look for the methods of Interface that you define and also declared
