Syntax

Copy

public class StrictlyLessThanAttribute : RangeAttribute

The StrictlyLessThanAttribute type exposes the following members.

Constructors

	Name	Description
	StrictlyLessThanAttribute(Double)	Initializes a new StrictlyLessThanAttribute with a given floating-point bound.
	StrictlyLessThanAttribute(Int64)	Initializes a new StrictlyLessThanAttribute with a given integer bound.
	StrictlyLessThanAttribute(UInt64)	Initializes a new StrictlyLessThanAttribute with a given UInt64 bound.

Properties

	Name	Description
	AttributeExclude	If true, indicates that this attribute removes all other instances of the same attribute type from the set of elements defined by the current instance. (Inherited from MulticastAttribute.)
	AttributeInheritance	Determines whether this attribute is inherited (Inherited from MulticastAttribute.)
	AttributePriority	Gets or sets the priority of the current attribute in case that multiple instances are defined on the same element (lower values are processed before). (Inherited from MulticastAttribute.)
	AttributeReplace	Determines whether this attribute replaces other attributes found on the target declarations. (Inherited from MulticastAttribute.)
	AttributeTargetAssemblies	Gets or sets the assemblies to which the current attribute apply. (Inherited from MulticastAttribute.)
	AttributeTargetElements	Gets or sets the kind of elements to which this custom attributes applies. (Inherited from MulticastAttribute.)
	AttributeTargetExternalMemberAttributes	Gets or sets the visibilities, scopes, virtualities, and implementation of members to which this attribute applies, when the member is external to the current module. (Inherited from MulticastAttribute.)
	AttributeTargetExternalTypeAttributes	Gets or sets the visibilities of types to which this attribute applies, when this type is external to the current module. (Inherited from MulticastAttribute.)
	AttributeTargetMemberAttributes	Gets or sets the visibilities, scopes, virtualities, and implementation of members to which this attribute applies. (Inherited from MulticastAttribute.)
	AttributeTargetMembers	Gets or sets the expression specifying to which members this instance applies. (Inherited from MulticastAttribute.)
	AttributeTargetParameterAttributes	Gets or sets the passing style (by value, out or ref) of parameters to which this attribute applies. (Inherited from MulticastAttribute.)
	AttributeTargetParameters	Gets or sets the expression specifying to which parameters this instance applies. (Inherited from MulticastAttribute.)
	AttributeTargetTypeAttributes	Gets or sets the visibilities of types to which this attribute applies. (Inherited from MulticastAttribute.)
	AttributeTargetTypes	Gets or sets the expression specifying to which types this instance applies. (Inherited from MulticastAttribute.)
	DisplayMaxValue	Gets the maximal value to be used when generating the error message, typically in the implementation of GetErrorMessageArguments(). (Inherited from RangeAttribute.)
	DisplayMinValue	Gets the minimal value to be used when generating the error message, typically in the implementation of GetErrorMessageArguments(). (Inherited from RangeAttribute.)
	ErrorMessage	Gets or sets the error message formatting string. (Inherited from LocationContractAttribute.)

Methods

	Name	Description
	CompileTimeValidate(Object)	Method invoked at build time to ensure that the aspect has been applied to the right target. (Inherited from RangeAttribute.)
	CompileTimeValidate(LocationInfo)	Validates that the current aspect has been applied to a valid location. (Inherited from LocationContractAttribute.)
	CreateArgumentException	Creates an ArgumentException with an error message formatted from ErrorMessage and given concrete values. (Inherited from LocationContractAttribute.)
	CreateArgumentNullException	Creates an ArgumentNullException with an error message formatted from ErrorMessage and given concrete values. (Inherited from LocationContractAttribute.)
	CreateArgumentOutOfRangeException	Creates an ArgumentOutOfRangeException with an error message formatted from ErrorMessage and given concrete values. (Inherited from LocationContractAttribute.)
	CreatePostconditionFailedException	Creates an PostconditionFailedException with an error message formatted from ErrorMessage and given concrete values. (Inherited from LocationContractAttribute.)
	FormatErrorMessage	Formats the ErrorMessage with concrete values. (Inherited from LocationContractAttribute.)
	GetErrorMessage	Gets unformatted error message as defined by the instance. (Overrides RangeAttribute.GetErrorMessage().)
	GetErrorMessageArguments	Gets values of additional arguments for error message associated with particular instance of LocationContractAttribute. There arguments can be referenced from error message string by {4}, {5} and so on. (Overrides RangeAttribute.GetErrorMessageArguments().)
	RuntimeInitialize	Initializes the aspect at runtime. (Inherited from LocationContractAttribute.)
	SelectSelfOrNothing	A pointcut that selects the target location of the current aspect, unless the target location is a dependency property or an attached property. (Inherited from LocationContractAttribute.)
	ValidateValueDynamic	Validates a weakly-typed (boxed) value, typically the value of a dependency property or an attached property. (Inherited from RangeAttribute.)

Remarks

Null values are accepted and do not throw an exception.

Floating-point values are tested to be greater than or equal to the maximum value plus a tolerance value. The tolerance value is equal to the distance of the value closest to the maximum value according to the precision of the respective floating-point numerical data type.

Error message is identified by StrictlyLessThanErrorMessage.

Error message can use additional argument

Field Value

Type:
{4} to refer to the minimum value used.
