mysql data type mapping (no replies)

I dont know if this is the right to place this post.

BTW i have problem, why tinyint(3) us treated as sbyte in .net(c#)?
I know that the mysqldatareader will return objets.

so i used typeof(), i was expecting that tiny will be int or short in .net.

can some explain about this.

BTW is there official datatype mapping for .net and mysql?

I will appreciate for any help will come.
thank you
