What exception to throw when a property setter is not allowed?

Question

I have a base class that has a virtual property:

public virtual string Name { get; set; } 

then I have a derived class that overrides only the getter of the property

public override string Name {     get { return "Fixed Name"; } } 

The problem is this only overrides the getter. If someone calls the setter the base class setter will get called, and the caller won't know that it's ineffective.

So I thought I'd do something like:

public override string Name {     get { return "Fixed Name"; }     set { throw new Exception(); } //which exception type? } 

So two (related questions):

1. Is there a better pattern for me to use?
2. If I should be using the above pattern, what exception to use?

Edit: Some reasons why one exception would be preferred over another would be good. My co-worker and I have had the same argument between NotSupported and InvalidOperation.

Answer 1

Throw NotSupportedException exception. Quote from the link:

There are methods that are not supported in the base class, with the expectation that these methods will be implemented in the derived classes instead. The derived class might implement only a subset of the methods from the base class, and throw NotSupportedException for the unsupported methods.

My opinion is that InvalidOperationException is not a correct option. Quote from MSDN:

The exception that is thrown when a method call is invalid for the object's current state.

There is nothing about current state in your situation. It is that the class contract does not support the operation.
