Check if a classes Property or Method is declared as sealed [duplicate]

This question already has an answer here:

• Find out if a property is declared virtual 2 answers

I've got following derivations:

interface IMyInterface
{
    string myProperty {get;}
}

class MyBaseClass : IMyInterface // Base class is defining myProperty as abstract
{
    public abstract string myProperty {get;}
}

class Myclass : MyBaseClass // Base class is defining myProperty as abstract
{
    public sealed override string myProperty 
    {
        get { return "value"; }
    }
}

I would like to be able to check if a member of a class is declared as sealed. Somewhat like that:

PropertyInfo property = typeof(Myclass).GetProperty("myProperty")

bool isSealed = property.GetMethod.IsSealed; // IsSealed does not exist

Sense of all this is to be able to run a test, that checks the code/project for consistency.

Following test fails:

PropertyInfo property = typeof(Myclass).GetProperty("myProperty")

Assert.IsFalse(property.GetMethod.IsVirtual);
