Interop Excel : Copy sheet and put it in another workbook

Question

Hello,

 

With Interop and C# .NET, I would like to copy a sheet from a workbook to put it in another workbook at the end.  

I have already done a search on the internet, but the examples given are often partial or don't work. 

 Would you have a simple example in C# that can copy a sheet from a workbook to put it in another workbook at the end please?

 

Thanks.
