you can add a usercontrol into umbraco by using macro. For this you have to create a web project and have to add its dll to your umbraco bin folder. If you have class files then by adding this dll you can use that class also.

you have to add the ascx files into usercontrol folder and have to create a macro using this usercontrol.
