Return the Sum() of a query, using LinQ and Lambda Expression

Question

I have this generic method in my repository for searching

public virtual IEnumerable<TEntity> Search(Expression<Func<TEntity, bool>> predicate)
{                
     return Dbset.Where(predicate);
}

And this one that searches all the Disable records of my entity

public IEnumerable<CodigosDeOperacao> GetDisabled()
{
     return Search(c => !c.Active && c.disabled).OrderBy(c=>c.Code);
}

I would like to return the number of disabled, because I will need to know if it equals zero.

So I created this method.

public CodigosDeOperacao GetTheAmmountOfDisable()
{
     //somthing like taht
     return Search(c=>c.Ativo).Sum();
}

How could I return these records using these methods using Lambda and LinQ?

Answer 1

Use Count instead of Sum

public CodigosDeOperacao GetTheAmmountOfDisable()
{
    //somthing like taht
    return Search(c=>c.Ativo).Count();
}
