ConsoleFX

Validators reference Validation in ConsoleFx can be performed for: option parameters, using the Option class ValidateWith extension method arguments, using the Argument class ValidateWith extension method Both ValidateWith methods accept a list of ... [More] validator class (deriving from BaseValidator) instances. The Option class has an additional overload that accepts the index of the parameter to validate.The ConsoleFx Declarative framework defines a validation attribute for each validation class.Note: Unless specifically mentioned, all validator classes have a property called ErrorMessage that allows you to customize the error message displayed in case it's validation check fails.BooleanValidatorCustomValidatorEnumValidatorEnumValidatorIntegerValidatorLookupValidatorPathValidatorRegexValidatorStringValidator BooleanValidator Validates whether the value is a valid .NET boolean value, i.e. True or False. BooleanValidator() CustomValidator Validates whether the value satisfies one or more custom conditions specified by a predicate function. CustomValidator(Func validator) validator: The predicate function that performs the custom check. EnumValidator Validates whether the value belongs to a specified enum type. EnumValidator(Type enumType, bool ignoreCase = true) enumType: The type of the enum to check against. The validator will throw an ArgumentException if the type if not an enum. ignoreCase: Specifies whether the check should be case sensitive. EnumValidator Generic version of the EnumValidator, providing a simpler syntax.This class derives from EnumValidator.; EnumValidator(bool ignoreCase = true) where TEnum : struct ignoreCase: Specifies whether the check should be case sensitibe. IntegerValidator Validates whether the value is an integer and optionally, whether it falls within a specific range. IntegerValidator(long minimumValue = long.MinValue, long maximumValue = long.MaxValue) minimumValue: Optional parameter specifying the minimum allowed value. maximumValue: Optional parameter specifying the maximum allowed value. LookupValidator Validates whether the value belongs to a predefined set of string values. LookupValidator(IEnumerable items) items: The predefined set of string values to check against. PathValidator Validates whether the value is a valid file or directory path, and optionally whether that path actually exists on the file system. PathValidator(PathType pathType = PathType.File, bool checkIfExists = true) pathType: Optional parameter specifying the type of path to check - file or directory. Defaults to file if not specified. checkIfExists: Optional parameter specifying whether to check for the path's existence on the file system. Defaults to true, if not specified. RegexValidator Validates whether the value matches a specified regular expression pattern. RegexValidator(Regex regex) regex: The Regex object containing the regular expression pattern to compare against. RegexValidator(string pattern) pattern: The regular expression pattern to compare against. StringValidator Validates whether the value's length falls within a specified range. StringValidator(int maxLength) maxLength: The maximum allowed length of the string. In this case, the minimum allowed length will be 0 (zero). StringValidator(int minLength, int maxLength) maxLength: The maximum allowed length of the string. minLength: The minimum allowed length of the string. [Less]
