Question

I have a method which returns a WorkInfo object. It has 2 properties CompanyName and WorkLocation.

It might happen that a person has worked at multiple companies. In this case i want to

1. Return an array of WorkInfo object

2. After the WorkInfo object is returned to calling method, i need to enumerate over it in following way

   foreach(WorkItem wRow in WorkInfo) 
   {
      string s1 = wRow.CompanyName ;
      string s2 = wRow.WorkLocation;
   }
   

How do i achieve this in C# ?

UPDATE :
All i need to do is return a collection of multiple objects of same type and loop over it using ForEach.

eg A datatable returns a collection of datarows and we can loop over it using ForEach(Datarow dr in datatable.Rows)

Similarly, what exactly should i do to return a collection of “WorkInfo” objects which i can loop over using ForEach ?

Here is another attempt:

Notes: quick code — not tested — I used your name conventions (ick CamelCase) etc.

public class WorkInfo
{
   public string CompanyName { Get; Set; };
   public string WorkLocation { Get; Set; };
}

public class Example
{

   public List<WorkInfo> GetAList()
   {
      List<WorkInfo> result = new List<WorkInfo>();

      result.Add(new WorkInfo { CompanyName = "MS", WorkLocation = "Redmond" });
      result.Add(new WorkInfo { CompanyName = "Google", WorkLocation = "New York" });
      result.Add(new WorkInfo { CompanyName = "Facebook", WorkLocation = "CA" });

      return result;
   }

   public UseAList()
   {
      foreach(WorkInfo wRow in  GetAList()) 
      {
        string s1 = wRow.CompanyName ;
        string s2 = wRow.WorkLocation;

        // process list elements s1 and s2
      }
   }
}

Here is some code that I believe solves your problem:

workInfo = FunctionThatReturnsArray(..);

if (workInfo.Length == 1)
{
   // process single item at workInfo[0]
}
else
{
  foreach(WorkItem wRow in WorkInfo) 
  {
    string s1 = wRow.CompanyName ;
    string s2 = wRow.WorkLocation;

    // process list elements s1 and s2
  }

}
