Hi everybody,

I am writing a method to delete a cient in my Repository class. Here is what I've started from:

public void DeleteClient(int clientId, bool autoCommit = true)
        {
            var ReordersQuery = from reord in this.Reorders
                                where reord.ClientId == clientId
                                select reord;

            if (ReordersQuery.Any())
                //throw "Client " + clientId.ToString() + " can not be deleted because it has related rows in the ReOrders table!";

        }

I read help on throw as I need to throw a new exception. My question is - what kind of exception it should be?

Thanks in advance.
