The NumberRangesAttribute type exposes the following members.

Constructors

	Name	Description
	NumberRangesAttribute()	Initializes a new instance of the NumberRangesAttribute class.
	NumberRangesAttribute(array<KeyAttributePair<NumberRangesAttribute>[])	Initializes a new instance of the NumberRangesAttribute class with the specified KeyAttributePair<T> instances.
	NumberRangesAttribute(Nullable<Double>, Nullable<Double>, Nullable<Double>, Nullable<Double>, Nullable<Boolean>)	Initializes a new instance of the NumberRangesAttribute class with the specified hard and soft limit values.
	NumberRangesAttribute(Nullable<Double>, Nullable<Double>, Nullable<Double>, Nullable<Double>, Nullable<Boolean>, array<KeyAttributePair<NumberRangesAttribute>[])	Initializes a new instance of the NumberRangesAttribute class.

Properties

	Name	Description
	CanBeAuto	Gets a value that indicates whether the range can be set automatically.
	HardMaximum	Get the hard limit on the maximum value.
	HardMinimum	Get the hard limit on the minimum value.
	Item	Gets the NumberRangesAttribute with the specified key.
	Maximum	Get the soft limit on the maximum value.
	Minimum	Get the soft limit on the minimum value.
	TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)

Methods

	Name	Description
	Equals	Determines whether the specified Object is equal to the current NumberRangesAttribute. (Overrides Attribute.Equals(Object).)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Returns the hash code for the current NumberRangesAttribute. (Overrides Attribute.GetHashCode().)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsDefaultAttribute	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
	Match	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Explicit Interface Implementations

	Name	Description
	_Attribute.GetIDsOfNames	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
	_Attribute.GetTypeInfo	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
	_Attribute.GetTypeInfoCount	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
	_Attribute.Invoke	Provides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

The NumberRangesAttribute allows for a difference between the hard and soft limits. The user can easily set values between the soft limits, but more effort is required to set the hard limits. For example, when working with color component values, some valid values will move the color out of gamut.

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.
