Question

I have a class, I am using list to get (assigning multiple list entry values in c#).

// This will return me more than 1 records.
List<ClassEmpInfo> employeeDetails =GetEmployeeInformation(); 

List<ClassEmployee> empInfo = null; 
foreach (ClassEmployee employee in employeeDetails) 
{
  //This needs to show all the ids belonging to employeeDetails.
  //If there are 3 different employee ids , 
  //the list empInfo should hold the output of all the 3, 
  //but i am getting the last 3rd one alone. 
  //How to cumulatively add 3 different employee ids.

  empInfo = GetEmployeeDetails(Id, EmpId); 
}

I am getting the last employee information rather than all the employee details in the empInfo list.

If the type is string I can do something like:

if (strType.Length > 0) 
{  
  strType = strType + returned values; 
} 
else
{  
  strType = strType; 
}

How do I add the list values cumulatively?

Answer 1

I think what you want to do is the following:

List empInfo = new List<detail_type>(); // whatever type is returned by GetEmployeeDetails
foreach (ClassEmployee employee in employeeDetails)
{
    empInfo.Add(GetEmployeeDetails(id, EmpId));
}

It’s rather unclear to me, though, if GetEmployeeDetails returns a single value or a list of values. If it returns a list of values, then change the line in the loop to:

empInfo.AddRange(GetEmployeeDetails(id, EmpId));
