How to get the Type of Class using GetType

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 method or propertiy available?

Try Type.FullName to get what you need - https://learn.microsoft.com/de-de/dotnet/api/system.type.fullname?view=netframework-4.7.2

So in your case - 

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

If you want to extract the type of the generic argument of the IEvent instance, you can do this - 

public EventDescriptor(Guid id, IEvent eventData)
 {
   AggregateId = id;
   EventData = eventData;
   if (!eventData.GetType().IsGenericType)
   {
       EventType = eventData.GetType().FullName;
   }
   else
   {
       // notice - this assumes we can take the FIRST generic argument, we don't check for others here
       EventType = eventData.GetType().GetGenericArguments().First().FullName;
   }
}
