Createa a directory(folder) dynamically

I would like to create a folder in the server path dynamically  ( if it exists then delete and recreate ) using C#

For example,

the server path is \\Server1\test$\data\

 

and I would llike to creat a folder under abover path called "Export1" ( the folder name can change dynamically) and if the folder exist , then overwrite.

 

how can I do this?

 

 

thanks,
