how store the exceptions in to database in c#

If you have stored "something" to the database already, you can store exceptions as well.

Exceptions are no exception (wow!) to any other piece of data.

However, having said that, you may also consider using custom, highly configurable, components specialised in logging exceptions in variety of ways, such as, Log4net.

You can use Try Catch in SQL Stored Procedure as well..
