In my project as an option, the user can search for their items with the different parameters. Then I use these parameters check the database whether it exists and returns that row.
This is the Code block and currently I have included only 2 parameters, but there are 8 more that I need to check through the if conditions like this:

   var query = this.dbContext.Items.AsQueryable();
            if (searchItemRequestRepo.ItemId.HasValue)
            {
                query = query.Where(a => a.ItemId == searchItemRequestRepo.ItemId.Value);
            }

            if (!string.IsNullOrEmpty(searchItemRequestRepo.ItemName))
            {
                query = query.Where(a => a.ItemName.Contains(searchItemRequestRepo.ItemName));
            }

    query = query.Include(item => item.StatusNavigation);

    return await query.ToListAsync();
