Interface IValidationEntry<T>

Defines members to be implemented by a type that allows configuring validation rules for a property.

Namespace: TheXDS.MCART.Types.Base

Assembly: MCART.Mvvm.dll

Syntax

public interface IValidationEntry<T>

Type Parameters

Name	Description
T	Type of the selected property.

Methods

AddRule(Func<T, bool>, string)

Adds a validation rule for the selected property.

Declaration

IValidationEntry<T> AddRule(Func<T, bool> rule, string error)

Parameters

Type	Name	Description
Func<T, bool>	rule	Function that performs the validation. The function must return true if the value passes the test, false otherwise.
string	error	Error message to display if the rule fails.

Returns

Type	Description
IValidationEntry<T>	The same validation-entry instance to allow Fluent syntax.

AddRule(Func<T, bool?>, string)

Adds a validation rule for the selected property.

Declaration

IValidationEntry<T> AddRule(Func<T, bool?> rule, string error)

Parameters

Type	Name	Description
Func<T, bool?>	rule	Function that performs the validation. The function must return true if the value passes the test, false otherwise. If the evaluator returns null, evaluation of any remaining rules that have not yet run will stop.
string	error	Error message to display if the rule fails.

Returns

Type	Description
IValidationEntry<T>	The same validation-entry instance to allow Fluent syntax.
