Creating Excel Sheet using C#

I suggest to use a c# excel file component, There are great 3rd party components in the market that do the same job (or even better).
From a comparison testing I performed about a year ago Spire.XLS for .NET is the best from the following perspectives:
1. Read/Write of excel
2. Support of embedding images
3. Size of result Excel file is very small
4. Convenient API and very similar to Office's one
5. Multi-threaded and multi-process support

Hy,
