Hi

I have to insert some content from database using c#. I am reading the data and placing it into models. Lets say 1 model is

public class Manufacturer
      {
            public int ManufacturerId { get; set; }
            public string ManufacturerName { get; set; }
     }

I have same Document type and 1 root document type Manufacturers. that can have multiple content of Manufacturer. Now I have read a list of manufacturers and I need to create a content for all of them. I have

 foreach (var man in manufacturers)
 {
         InsertUmbracoManufacturer(man);
 }

and if manufacturer with mamufacturerId(not same as UmbracoId) exists update in else insert new. So far I have:

public void InsertUmbracoManufacturer(Manufacturer man)
        {
            //get the manufacturer folder 
            IContentService contentService = ApplicationContext.Current.Services.ContentService;
            var rootFolder =contentService.GetRootContent().Where(x => x.ContentType.Alias.Equals("Manufacturers")).First();
            if (rootFolder!=null)
            {
                //get the node with manufacturerId =man.manufacturerId
                var m=rootFolder.Children().Where(x=>x.ContentType.Alias.Equals("Manufacturer") && x.Children().Where(y=>y.Properties["manufacturerid"].Equals(man.ManufacturerId))  //not so sure please help
                if (m!=null)
                {
                    //if it does exist update it help here too
                }
                else
                {
                    //if it doesn't exist insert help here too
                }
            }

Please help
