How combine two or more lists into one list

Question

Hi Friends, 

 I am having a requirement like below. 

 class Final

 {

 public string EmployeName{get;set;} 

public string Gender{get;set;}

 public string DepartId{get;set;} 

public string DepartName{get;set;} 

public string SalaryId{get;set;}

 public string Salary{get;set;}

 } 

 class Emp {

 public string EmployeName{get;set;} 

public string Gender{get;set;}

  }  

class Department {

 public string DepartId{get;set;

} public string DepartName{get;set;} 

} class Salary 

{ public string SalaryId{get;set;} public string Salary{get;set;}

 }

 Having the list of Final, Emp, Department and Salary like below 

 lstFinal, lstEmp,lstDepartment,lstSalary  

 Want a linq query with  final list to be a combination of lstEmp, lstDepartment,lstSalary  

Please kindly help me out. 

What I have tried:  

var result= from e Emp   join d in dept on e.EmployeName equals e.EmployeName  

join g in gend on g.Gender equals g.Gender

 select new Final(){EmployeName=e.EmployeName, Gender=e.Gender, DepartId=d.DepartId, DepartName=d.DepartName,SalaryId=s.SalaryId,Salary=s.Salary}
