What you are looking at is likely not VB.NET, but VBA (Visual Basic for Applications). VBA is an ancestor of VB.NET, and the language that is used for Excel macros. The bad news for you is, VBA isn't a .NET language, and you can't use C# for macros "attached" to a workbook.

If you are really motivated to use C#, your best option is to look into ExcelDNA , which among other things allows you to call .NET dlls from Excel.

However, I would really question the need to convert to C#, given the problem you describe. VBA is the "natural" language for lightweight Excel automation, and is fairly understandable. If you have existing code, just modify it. And one of the nice features of Excel VBA is the macro recorder, which allows you to record your interactions with Excel as VBA code, which is a great way to figure out how things are used in the object model.
