Sharing of Property in a DTO using Category attribute c#

Question

I'm working on Employee Model, it contains all the information about the Employee already I posted the same in How to use the DTO efficiently based on Scenario in C#. How could I share the single property for the multiple groups using Category attribute c#.

For Example:

public class Employee
{
    public int EmployeeId { get; set; }
    public string FirstName { get; set; }
    public string MiddleName { get; set; }
    public string LastName { get; set; }
    public string EmailAddress { get; set; }
    public string HomePhone { get; set; }
    public string MobilePhone { get; set; }
}

I'm having the following four methods for fetching records of Employee

public Employee GetEmployeeName(int id)
{
    // The return should contain only FirstName, MiddleName and LastName. 
    // The rest of the properties should be non-accessable (i.e., Private)
}

public Employee GetEmployeeContacts(int id)
{
    // The return should contain only EmailAddress, HomePhone and MobilePhone. 
    // The rest of the properties should be non-accessable (i.e., Private)
}

public Employee GetEmployeeNameEmail(int id)
{
    // The return should contain only FirstName, MiddleName, LastName and EmailAddress. 
    // The rest of the properties should be non-accessable (i.e., Private)
}

public Employee GetEmployee(int id)
{
    // It should return the entire Employee object
}

How could I achieve this? could you please any one help in this regards.

Create a EmployeeNameDto, EmployeeContactsDto etc... only with the properties you want share. In your method instance dto and set values and return the dto — ArDumez, Dec 11 '16 at 12:49

A sample, this is the common use for DTO:

public class EmployeeNameDto
{
    public int EmployeeId { get; set; }
    public string FirstName { get; set; }
    public string MiddleName { get; set; }
    public string LastName { get; set; }
}

public EmployeeNameDto GetEmployeeName(int id)
{
    Employee emplpoyee = employeeRepository.Find(id):
    return new EmployeeNameDto() {
      EmployeeId = emplpoyee.EmployeeId,
      FirstName = emplpoyee.FirstName,
      MiddleName = emplpoyee.MiddleName,
      LastName = emplpoyee.LastName
    };
}

Or

public class Employee
{
    public int EmployeeId { get; set; }
    public string FirstName { get; 
      set {
        if (condition == false)
          throw new Exception(" is Read Only !")
      }
    }
    public string MiddleName { get; set; }
    public string LastName { get; set; }
    public string EmailAddress { get; set; }
    public string HomePhone { get; set; }
    public string MobilePhone { get; set; }
}
