CustomConstantAttribute Class

Defines a constant value that a compiler can persist for a field or method parameter.

Namespace: System.Runtime.CompilerServices
Assembly: mscorlib (in mscorlib.dll)

[SerializableAttribute] 
[ComVisibleAttribute(true)] 
[AttributeUsageAttribute(AttributeTargets.Field|AttributeTargets.Parameter, Inherited=false)] 
public abstract class CustomConstantAttribute : Attribute
/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */ 
/** @attribute AttributeUsageAttribute(AttributeTargets.Field|AttributeTargets.Parameter, Inherited=false) */ 
public abstract class CustomConstantAttribute extends Attribute
SerializableAttribute 
ComVisibleAttribute(true) 
AttributeUsageAttribute(AttributeTargets.Field|AttributeTargets.Parameter, Inherited=false) 
public abstract class CustomConstantAttribute extends Attribute
Not applicable.

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 occurrences of custom constant attributes easily.

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

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