Adding a folder to a Sharepoint list

From http://blogs.msdn.com/adamhems/archive/2007/08/30/progammatically-adding-folders-to-a-sharepoint-list.aspx

string siteUrl = "http://sample.development.com/sales/prospects";
string listName = "Shared Documents";

SPSite siteCollection = new SPSite(siteUrl);
SPWeb site = siteCollection.OpenWeb();
SPList list = site.Lists[listName];

SPListItem folder = list.Items.Add(list.RootFolder.ServerRelativeUrl, SPFileSystemObjectType.Folder, null);

if (folder != null)
{
folder["Name"] = "NameofFolder";
folder.Update();
}

Differentiate between contact and account (customerid)

if(opportunity.customerid.type == EntityName.account.ToString())
{

if(account.revenue != null)
{
opportunity.new_accountvalue = new CrmMoney();
opportunity.new_accountvalue.Value = account.revenue.Value;
}
}
else if(opportunity.customerid.type == EntityName.contact.ToString())
{
contact contact = (contact)service.Retrieve(EntityName.contact.ToString(), opportunity.customerid.Value, new AllColumns());

if(contact.creditlimit != null)
{
opportunity.new_accountvalue = new CrmMoney();
opportunity.new_accountvalue.Value = contact.creditlimit.Value;
}
}

service.Update(opportunity);

public override void PostCreate(...)
{
Guid opportunityId = task.regardingobjectid.Value;
this.opportunity = (opportunity)service.Retrieve(EntityName.opportunity.ToString(), opportunityId, new AllColumns());

opportunity.new_textfield = "hello world"; // throws a NullReferenceException

string newtext = "hello world";
opportunity.new_textfield = newtext; // works fine
}
