Increment Tablix objects in c#

Hi,

I am converting crystal reports to ssrs reports and I am converting area sections of crystal reports to tablix in ssrs.

Below code is the object declaration.

Tablix tab = new Tablix();
tab.Name = crsec.ObjName;
TablixBody tabb = new TablixBody();
TablixColumn tabcol = new TablixColumn();
TablixRow tabrow = new TablixRow();
TablixHierarchy tcolHier = new TablixHierarchy();
TablixHierarchy trowHier = new TablixHierarchy();
List<TablixCell> tabcells = new List<TablixCell>();

Now how can I increment all these object names in for each loop, so that each object will have its unique ID on each iteration.
