Calling DynamicModulemanager SaveChanges in Loop

Hello everybody,

I am new to sitefinity development and I am not sure if I am on correct path with solving my problem.

I have a bunch of Partners. They are represented as dynamic modules in my Sitefinity CMS. My task is to switch the Default Image with new image provided by my design department.

Can I call

dynamicModuleManager.SaveChanges();
dynamicModuleManager.Lifecycle.Publish(partner);
dynamicModuleManager.SaveChanges();

in a loop so many times(cca 500)?

I have written code as follows:

var providerName = "dynamicProvider5";

DynamicModuleManager dynamicModuleManager = DynamicModuleManager.GetManager(providerName);

Type myCustomPartnerType = TypeResolutionService.ResolveType("Telerik.Sitefinity.DynamicTypes.Model.BTCPartners.MyCustomPartnerType ");

var myCollection = dynamicModuleManager.GetDataItems(bTCPartnerType).Where(d => d.Status == ContentLifecycleStatus.Master);

foreach (var partner in myCollection)

{

Image emptyHeroImage = partner.GetRelatedItems< Image >("HeroImage").Where(d => d.Status == ContentLifecycleStatus.Master && d.GetValue("Title") == "DefaultImage").FirstOrDefault();

if (emptyHeroImage != null)

{

Image newImage = GetImage(partner.GetString("PartnerID"));

if (newImage!=null)

{

partner.DeleteRelation(emptyHeroImage , "HeroImage");

partner.CreateRelation(newImage, "HeroImage");

dynamicModuleManager.SaveChanges();

dynamicModuleManager.Lifecycle.Publish(partner);

dynamicModuleManager.SaveChanges();

}

}

}
