cell with the heading from C#

oRng = oSheet.UsedRange;
Excel.Range oR = oRng.Find("Date", omissing,
Excel.XlFindLookIn.xlValues, Excel.XlLookAt.xlPart,
Excel.XlSearchOrder.xlByRows, Excel.XlSearchDirection.xlNext, false,
omissing, omissing);

I'm now atloos as to how to get column selected or apply format to a col.
string s = oR.ToString();
