Sitecore manual publish an item in all publishing targets and languages

Some times we need to tigger sitecore publish on an item on all publishing targets and on all languages. Here is the way we can achive it.

To get all publishing target database names:

var publishingTargetDatabaseNames = Sitecore.Publishing.PublishManager.GetPublishingTargets(
                                    Sitecore.Configuration.Factory.GetDatabase("master"))
                                    .Select(x => x["Target database"]).ToArray();

To get all languages for master database:

var publishingTargetLanguages = Sitecore.Configuration.Factory.GetDatabase("master").Languages;

To trigger a manual publish in sitecore:

Sitecore.Publishing.PublishManager.PublishItem(itemsToPublish.FirstOrDefault(),	publishingTargetDatabaseNames.Select(Sitecore.Configuration.Factory.GetDatabase).ToArray(),
	publishingTargetLanguages,
	deep: true,
	compareRevisions: true, //Do smart publish for the item	publishRelatedItems: true);

To clear sitecore cache manually:

 Sitecore.Caching.CacheManager.ClearAllCaches();

Adding all together in item publish event: 

var publishingTargetDatabaseNames = Sitecore.Publishing.PublishManager.GetPublishingTargets(
                                    Sitecore.Configuration.Factory.GetDatabase("master"))
                                    .Select(x => x["Target database"]).ToArray();
var publishingTargetLanguages = Sitecore.Configuration.Factory.GetDatabase("master").Languages;Sitecore.Publishing.PublishManager.PublishItem(itemsToPublish.FirstOrDefault(),
												publishingTargetDatabaseNames.Select(Sitecore.Configuration.Factory.GetDatabase).ToArray(),
												publishingTargetLanguages,
												deep: true,
												compareRevisions: true, //Do smart publish for the item
												publishRelatedItems: true);
//Clear cache manuallySitecore.Caching.CacheManager.ClearAllCaches();

Deep : this parameter specifies whether to include subitems or not. If you only want to publish item go for false.

Compare Revisons: this parameter specifies if this publish is smart publish or republish. Go for true if u want smart publish. Going for republish is necessary sometimes due to media items but keep an eye on performance.

publishingTargetDatabases is array of databases.
