Private const

Some odd attribute defining behavior.

Let's define a class with some constants:

class Foo

{

       public const string String = "some string";

       protected const Type Type = null;

       private const int Int = 42;

}

It's strange but you can access these constants in attribute definition, even protected and public, even without class name specialized!

[MyAttribute(String, Int, Type)]

class Foo

{

       public const string String = "some string";

       protected const Type Type = null;

       private const int Int = 42;

}

class MyAttribute :Attribute

{

       public MyAttribute(string someString, int someInt, Type someType)

       {             

       }

}

Note, that Type constant could be set to null only, because constant initializer must be compiler-time constant and even typeof(Foo) is not a compile-time constant. But it is possible to use typeof(Foo) in attribute definition:

[MyAttribute(String, Int,  typeof(Foo))]

class Foo

{

       public const string String = "some string";

       protected const Type Type = null;

       private const int Int = 42;

}
