Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Remarks

You can apply this attribute to fields or parameters.

This class cannot be instantiated.

Compilers should create specific classes, derived from this class, that define the type of the constant value. For example, see the DateTimeConstantAttribute which allows a compiler to persist an 8-byte DateTime constant for a field or method parameter. If you are using System.Reflection, this pattern of deriving specific classes from CustomConstantAttribute enables you to find all occurances of custom constant attributes easily.

The classes in System.Runtime.CompilerServices are for compiler writers use only.
