More code? Aren't you joking? Even this code is way too much. Rather, OP needs to explain what is he trying to achieve.
I answered based on this code, please see...

So what? I answered. The OP's comment is nearly useless. Everyone should understand what one is doing. If this is too hard, one should do simpler job at first.

Solution 2

Try this..

C#

string[] departmetnNames;
       List<string> lstTemp = new List<string>();
       foreach (var item in objActiveDept)
       {
           lstTemp.Add(item.DepartmentName);
       }
       departmetnNames = lstTemp.ToArray();

Solution 1

It is quite unclear what do you want to achieve, so I cannot answer this question because this is not a valid question.

All I can advise is: look at your code: it makes no sense at all. You create some array object inside loop, assign its reference to some local variable and immediately loose this object when you go to next iteration. Please don't ask me "what to do instead", because I have no idea what you want to achieve; just don't do what makes no sense for any purpose.

look on objActiveDept i have all ids department which i have get from query.
Now i want to det deparments name using foreach loop and save into an array.
hope you understand now

Sergey Alexandrovich Kryukov 6-Feb-14 2:16am

I already took a look at it. Now it's your turn to look. You are looking but not seeing.
This is you who don't understand.
Do you need array, or array of arrays (to hold all the items)?

You did not show declaration of the Employee_AttandanceLogs_PR_View. It should have DepartmentName. But is DepartmentName an array, too? Why?!
Maybe all you need is to call
objActiveDept.ToArray().

My 5 to counter the silly downvote.
Please, be patient :-)

Thank you, Carlo.
Not a big deal; for the ignorant, it's usual to blame others... :-)
