Clean data from database c#

Clean data from database c#

I using ORM telerik open access in my project. I can use it to create and
add data to my database. Now i want to clean all data from my database. I
can do it by delete data from each table but it will take long code. I
have google how to clean it using DBContext and found nothing. There
another way to clean database but not looping to call delete function for
each table in my DB?
