how to get the tye of class using GetType c#?

Here i am using GetType() to get the type of eventData as follows,

public EventDescriptor(Guid id, IEvent eventData)
 {
   AggregateId = id;
   EventData = eventData;
   EventType = eventData.GetType().AssemblyQualifiedName;
}

which returns

 "EventType": "Shared.Events.EntityCreatedEvent`1[[Shared.Model.Dto.EntityDto, Shared, Version=1.0.6928.25697, Culture=neutral, PublicKeyToken=null]], Shared, Version=1.0.6928.25697, Culture=neutral, PublicKeyToken=null"

how can i get only the Shared.Model.Dto.EntityDto from the above? is there any methods or properties available?
