Reference returns

Reference returns allows a method to return an object as a reference instead of its value. We can define the reference return value by adding a ref keyword before the type in the method signature and when returning the object from the method itself.

Here is the signature of the method that allows reference returns:

public ref Person GetPersonInformation(int ID); 
 
Following is the implementation of the GetPersonInformation method that uses the ref keyword while returning the person's object.  
 
Person _person; 
public ref Person GetPersonInformation(int ID) 
{ 
  _person = CallPersonHttpService(); 
  return ref _person; 
}
