Validation rule that allows you to check combinations of rules created with AND logical operations.
Inherits: IValidationRule
Description
The AndRule class allows you to validate combinations of rules created with AND logical operations.
Important points
- When one or more of the combined rules return errors, then this rule returns all the errors that appeared.
- When none of the combined rules returns errors, then this rule also returns no errors.
Constructors
Creates a new validation rule and sets its values.
public
AndRule(params IValidationRule[] rules)
- rules: IValidationRule[] - list of rules to join with AND operator
Instance methods
Validate
Validates a given value against this rule.
public
void Validate(string path, Schema schema, object value, List<ValidationResult> results)
- path: string - dot notation path to the value.
- schema: Schema - schema this rule is called from
- value: object - value to be validated.
- results: List<ValidationResult> - list with validation results to add new results.
Example
var schema = new Schema().WithRule(new AndRule(
new ValueComparisonRule("GTE", 1),
new ValueComparisonRule("LTE", 10)
));
schema.Validate(0); // Result: 0 must be greater or equal to 1
schema.Validate(5); // Result: no error
schema.Validate(20); // Result: 20 must be letter or equal 10
