Is it possible to have different access modifiers on the get/set methods of a property?
No. The access modifier on a property applies to both its get and set accessors. What you need to do if you want them to be different is make the property read-only (by only providing a get accessor) and create a private/internal set method that is separate from the property.

Yes,it is possible for get and set to have different access modifiers,but one of the accessors must follow the access level of property.

.NET run time relies on the object reference counts to manage memory
A) TrueB) FalseExplanation: .Net run time relies on Garbage Collection to manage memory
vshylaja
- Apr 7th, 2008
One of the primary design goals of .NET is to overcome problems associated reference counting and orphaned objects etc that were prevalent in the COM world. .NET framework instead uses reference tracking for garbage collector to reclaim memory from unused objects.
