AndRule

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
