Update multi valued properties in SharePoint User Profile withSharePoint Object Model (SSOM)

I have a wrote post on updating SharePoint user profile with SharePoint Server Object model (SSOM) which is as below and this sample of code ellaborates on how you can update user profile properties of multi-valued.

Update below link with the latest

Update multi valued property

<pre class="brush: csharp">

//Higher permissions requires anyway to access secure data! So elevate

SPSecurity.RunWithElevatedPrivileges(delegate()
{
SPServiceContext serviceContext = SPServiceContext.GetContext(site);
UserProfileManager userProfileMgr = new UserProfileManager(serviceContext);
ProfilePropertyManager profilePropMgr = new UserProfileConfigManager(serviceContext).ProfilePropertyManager;

// Retrieve all properties for the "UserProfile" profile subtype,
// and retrieve the property values for a specific user to udpate
ProfileSubtypePropertyManager subtypePropMgr = profilePropMgr.GetProfileSubtypeProperties("UserProfile");
UserProfile userProfile = userProfileMgr.GetUserProfile(accountName);
// If you need to persist existing values, comment below line
userProfile[property].Clear();

// Add a value to a multi-value user property..and mapping
foreach (var prop in propertyValueCollection)
userProfile[property].Add((object)prop);

// Save the changes to the server.
userProfile.Commit();
Console.WriteLine("Success on updating account : " + accountName + "with values of : " + propertyValueCollection + "property :" + property);

});

</pre>

Important!

Multi value properties should be marked as multi valued in the managed user properties.
