ASP. NET Dynamic loading assembly creates an instance of the specified class and invokes the specified method

There are three methods in the following classes:

LoadAssembly: Loading the assembly for the specified path

GetInstance: Dynamically getting instances from type, using generics to return types

Executemothod: Executing the specified method in the instance
