I'm using .NET Framework 3.5 and when i run an asp.net application on local machine it'll working fine but after IIS hosting i'm getting object reference not set to an instance of an object error... here what can i do?

mostly correct but the question is i already had one excel template( It contains two worksheets, Example: "Test.xlsx") then i have to write one new worksheet like "New.xlsx"(It's a worksheet name) from the dataset on the same template: "Test.xlsx" . after write the dataset values on the excel template, the template name will be save as "Test_D1234_00.xlsx".<br>
Here how can i write the dataset vlues on the Excel template like "Test.xlsx" using asp.net with c# ?<br>
 <br>
Thanks and regards,<br>
