Class Validator<TRequest>

inherit from this base class to define your dto validators

HINT: validators are registered as singletons. i.e. the same validator instance is used to validate each request for best performance. hance, do not maintain state in your validators.

Syntax

public abstract class Validator<TRequest> : AbstractValidator<TRequest>, IValidator<TRequest>, IValidator, IEnumerable<IValidationRule>, IEnumerable, IServiceResolverBase where TRequest : class

Type Parameters

Name	Description
TRequest	the type of the request dto

Methods

CreateScope()

if you'd like to resolve scoped or transient services from the MS DI container, obtain a service scope from this method and dispose the scope when the work is complete.

using var scope = CreateScope();
   var scopedService = scope.Resolve<MyService>();

Declaration

public IServiceScope CreateScope()

Returns

Type	Description
IServiceScope

PreValidate(ValidationContext<TRequest>, ValidationResult)

Determines if validation should occur and provides a means to modify the context and ValidationResult prior to execution. If this method returns false, then the ValidationResult is immediately returned from Validate/ValidateAsync.

Declaration

protected override bool PreValidate(ValidationContext<TRequest> context, ValidationResult result)

Parameters

Type	Name	Description
ValidationContext<TRequest>	context
ValidationResult	result

Returns

Type	Description
bool

Overrides

FluentValidation.AbstractValidator<TRequest>.PreValidate(FluentValidation.ValidationContext<TRequest>, FluentValidation.Results.ValidationResult)

Resolve(Type)

resolve an instance for the given type from the dependency injection container. will throw if unresolvable.

Declaration

public object Resolve(Type typeOfService)

Parameters

Type	Name	Description
Type	typeOfService	the type of the service to resolve

Returns

Type	Description
object

Exceptions

Type	Condition
InvalidOperationException	Thrown if requested service cannot be resolved

Resolve<TService>()

resolve an instance for the given type from the dependency injection container. will throw if unresolvable.

Declaration

public TService Resolve<TService>() where TService : class

Returns

Type	Description
TService

Type Parameters

Name	Description
TService	the type of the service to resolve

Exceptions

Type	Condition
InvalidOperationException	Thrown if requested service cannot be resolved

TryResolve(Type)

try to resolve an instance for the given type from the dependency injection container. will return null if unresolvable.

Declaration

public object? TryResolve(Type typeOfService)

Parameters

Type	Name	Description
Type	typeOfService	the type of the service to resolve

Returns

Type	Description
object

TryResolve<TService>()

try to resolve an instance for the given type from the dependency injection container. will return null if unresolvable.

Declaration

public TService? TryResolve<TService>() where TService : class

Returns

Type	Description
TService

Type Parameters

Name	Description
TService	the type of the service to resolve
