How to get template ID of an item with glass.mapper?

Question

Is there a way to check the template ID of a Sitecore item with glass mapper?

My business logic would do the following:

1. Get the context item
2. If the context item has specific template it is OK
3. If it has a different template, then find another item with that template according to some business rules which also check the template

I would like to use the SitecoreContext class, described here: http://www.glass.lu/Mapper/Sc/Documentation/ISitecoreContext

My code looks like this:

var context = new SitecoreContext(); 

var currentItem = context.GetCurrentItem<MyModel>();

if(HasCorrectTemplate(currentItem))
{
   return currentItem;
}

return GetFallbackItem();

I don't really want to customize Glass Mapper for this, since it seems to me it should be a basic feature to check the template ID.

I can only think of using some kind of tricky query for this and I didn't find documentation about an other possibility.

You can also add the SitecoreInfoType.TemplateId attribute to a property on your model which Glass will then map to the TemplateID of the item.

//Returns the template ID of the item as type System.Guid.
[SitecoreInfo(SitecoreInfoType.TemplateId)]
public virtual Guid TemplateId{ get; set; }

You can then check the template id against your item

if(currentItem.TemplateId == {guid-of-template-to-match})
{
   return currentItem;
}

The solution from @Maras is cleaner but it depends on the set up of your templates and may depend on whether you are using Code Generation templates using TDS for example.
