Get the last data filled excel row number in C# -

-

i have been trying row number effectively. fails data cleared , cells not explicitly deleted.

i guess because of "used range".

what did using epplus 

using (var excel = new excelpackage(hpf.inputstream)) {     var ws = excel.workbook.worksheets["sheet1"];      if(ws.dimension.end.row > 2003)     {         var result = new jsonresult();         result.data = "filelimitexceeded" ;

but gives me incorrect data. how last count effectively.

i found 

var lastrow =  cells.find("*", [a1], , , xlbyrows, xlprevious).row;

but namespaces not comprehend. me complete , correct answer ?

i have come senario few days before, did read data , put in data table, , filter data show records when data not null. can go same approach.
