공개 메소드들

메소드	설명
Compile ( Type validationContextType, bool force = false ) : void	Parses and compiles expression provided to the attribute. Compiled lambda is then cached and used for validation purposes.
Equals ( object obj ) : bool	Determines whether the specified System.Object, is equal to this instance.
FormatErrorMessage ( string displayName, string expression, Type objectType, Guid>.IDictionary &fieldsMap ) : string	Formats the error message for client (value indicators not resolved - replaced by guids to be dynamically extracted by client-code). This method interprets custom format specifiers, provided to error message string, for which values or display names of model fields are extracted. Specifiers should be given in braces (curly brackets), i.e. {fieldPath[:indicator]}, e.g. {field}, {field.field:n}. Braces can be escaped by double-braces, i.e. to output a { use {{ and to output a } use }}.
FormatErrorMessage ( string displayName, string expression, object objectInstance ) : string	Formats the error message for user. This method interprets custom format specifiers, provided to error message string, for which values or display names of model fields are extracted. Specifiers should be given in braces (curly brackets), i.e. {fieldPath[:indicator]}, e.g. {field}, {field.field:n}. Braces can be escaped by double-braces, i.e. to output a { use {{ and to output a } use }}.
GetHashCode ( ) : int	Returns a hash code for this instance.
GetPriority ( ) : int?	Gets the value of Priority if it has been set, or `null`.
ToString ( ) : string	Returns a System.String that represents this instance.

메소드	설명
ExpressiveAttribute ( string expression, Func errorMessageAccessor ) : System	Constructor for expressive validation attribute. Allows for providing a resource accessor function that will be used to retrieve the error message. An example would be to have something like, e.g. CustomAttribute() : base( () => MyResources.MyErrorMessage ) {}.
ExpressiveAttribute ( string expression, string errorMessage ) : System	Constructor for expressive validation attribute.
IsValid ( object value, System.ComponentModel.DataAnnotations.ValidationContext validationContext ) : System.ComponentModel.DataAnnotations.ValidationResult	Validates a specified value with respect to the associated validation attribute.
IsValidInternal ( object value, System.ComponentModel.DataAnnotations.ValidationContext validationContext ) : System.ComponentModel.DataAnnotations.ValidationResult	Validates a specified value with respect to the associated validation attribute. Internally used by the ExpressiveAttribute.IsValid(object,System.ComponentModel.DataAnnotations.ValidationContext) method.

FormatErrorMessage() 공개 메소드

Formats the error message for client (value indicators not resolved - replaced by guids to be dynamically extracted by client-code).

This method interprets custom format specifiers, provided to error message string, for which values or display names of model fields are extracted. Specifiers should be given in braces (curly brackets), i.e. {fieldPath[:indicator]}, e.g. {field}, {field.field:n}. Braces can be escaped by double-braces, i.e. to output a { use {{ and to output a } use }}.
