Question

How to convert objExcel = CreateObject( its in vb..how it will be used in c#? Excel.Application ) this line to c#

I assume the VB code is not VB .Net code. The VB code would be different for VB .Net and it would be more relevant for use in C# too. I think that CreateObject will create an unmanaged COM object whereas for .Net it is better to use .NET Framework assemblies. You can do that by adding the relevant Excel and Office references. There are many articles in this web site about that. I show a sample in Problem with Exporting data into Excel using C# but please also look at the articles in this web site.

If you need to create a late bound object then I'd try this: Type t = Type.GetTypeFromProgID(Excel.Application); object objExcel = System.Activator.CreateInstance(t); Alternatively you can add a reference to Microsoft.VisualBasic.dll to your C# application and then add this using directive: using Interaction = Microsoft.VisualBasic.Interaction; You can then call CreateObject directly as follows: object objExcel = Interaction.CreateObject(Excel.Application);
