Here I'm getting a list Employee in which i have below properties and a list ContactDetails which is a list containing atleast 3 elements for its properties. For eg 3 types of ContactTypeName and ContactValue as Home: 000000000, work: 9999999, mobile: [phone]. For a businessUnitid i got all employeeid for a perticular EmployeeID i want contact details but i'm unable to get or 3 contactvalue and contactname. In list Employee there is list ContactDetails in which there would be 3 or 5 contact numbers. I don't know how must i assign it to a list.

As employee can have multiple contact details, you need to add contact detail list property to EmployeeData class
Model classes :
Public class EmployeeDetails
{
public EmployeeDetails()
{
EmployeeInfo = new List<EmployeeData>();
}
public long BusinessUnitID { get; set; }
public List<EmployeeData> EmployeeInfo { get; set;}
}
public class EmployeeData
{
public EmployeeData()
{
Contacts = new List<ContactInfo>();
}
public long EmployeeID { get; set;}
public string EmployeeName { get; set;}
public List<ContactInfo> Contacts { get; set; }
}
Public class ContactInfo
{
public string ContactName { get; set; }
public long ContactValue { get; set; }
}
Then it's easy to pass the data of employees with multiple contacts
public ActionResult Update(long BusinessUnitID=2)
{
if (Session[Constants.Session_IsAdmin] != null && Convert.ToBoolean(Session[Constants.Session_IsAdmin]))
{
List<Employee> employees = GetEmployeeById(Convert.ToInt64(BusinessUnitID));
List<EmployeeData> lstEmployeeData = new List<EmployeeData>();
foreach(var item in employee.Where(x => x.BusinessUnitID == BusinessUnitID))
{
EmployeeData employeeData = new EmployeeData();
employeeData.EmployeeID = item.EmployeeID;
employeeData.EmployeeName = item.EmployeeName;
foreach (var contact in employee.ContactDetails)
{
ContactInfo contactInfo = new ContactInfo();
contactInfo.ContactName = contact.ContactName;
contactInfo.ContactValue = contact.ContactValue;
employeeData.Contacts.Add(contactInfo);
}
lstEmployeeData.Add(employeeData);
}
EmployeeDetails empDetails = new EmployeeDetails();
empDetails.EmployeeInfo = lstEmployeeData;
return View(empDetails);
}
else
{
return RedirectToAction("Login");
}
}
