c# - Sorting a collection by multiple fields

I need to sort a collection. For example, I have

Austin 12/3/2012   
Sam 100 12/3/2012   
Sam 200 14/3/2012   
Bubly 300 12/3/2012   
Bubly 300 15/3/2012  
ram 100 13/3/2012 

Now if the sort order is Name, datetime then output should be

Austin 12/3/2012    
Bubly 12/3/2012   
Bubly 15/3/2012   
ram 13/3/2012    
sam 12/3/2012    
sam 14/3/2012  

If he sort order is Datetime , Name then it should be

12/3/2012 austin
12/3/2012 bubly
12/3/2012 sam
13/3/2012 ram
14/3/2012 sam
15/3/2012 bubly 

Accordingly for other items. How do i do this ? How do I take the order of columns for sorting.

You can use Linq function ThenBy after using OrderBy to perform further sorting.

listOfRecords.OrderBy(p => p.Name).ThenBy(p => p.Date)
