Microsoft.Extensions.Validation
Represents an interface for validating a value.
Validates the specified .
The value to validate.
The validation context.
A cancellation token to support cancellation of the validation.
A representing the asynchronous operation.
Provides an interface for resolving the validation information associated
with a given or .
Gets validation information for the specified type.
The type to get validation information for.
The output parameter that will contain the validatable information if found.
if the validatable type information was found; otherwise, false.
Gets validation information for the specified parameter.
The parameter to get validation information for.
The output parameter that will contain the validatable information if found.
if the validatable parameter information was found; otherwise, false.
Indicates that a property, parameter, or a type should not be validated.
When applied to a property, validation is skipped for that property.
When applied to a parameter, validation is skipped for that parameter.
When applied to a type, validation is skipped for all properties and parameters of that type.
This includes skipping validation of nested properties for complex types.
Determines whether the specified type is an enumerable type.
The type to check.
if the type is enumerable; otherwise, .
Determines whether the specified type is a nullable type.
The type to check.
if the type is nullable; otherwise, .
Tries to get the from the specified array of validation attributes.
The array of to search.
The found if available, otherwise null.
if a is found; otherwise, .
Gets all types that the specified type implements or inherits from.
The type to analyze.
A collection containing all implemented interfaces and all base types of the given type.
Determines whether the specified type implements the given interface.
The type to check.
The interface type to check for.
True if the type implements the specified interface; otherwise, false.
Contains validation information for a parameter.
Creates a new instance of .
The associated with the parameter.
The parameter name.
The display name for the parameter.
Gets the parameter type.
Gets the parameter name.
Gets the display name for the parameter.
Gets the validation attributes for this parameter.
An array of validation attributes to apply to this parameter.
If the parameter is a collection, each item in the collection will be validated.
If the parameter is not a collection but has a validatable type, the single value will be validated.
Contains validation information for a member of a type.
Creates a new instance of .
Gets the member type.
Gets the member type.
Gets the member name.
Gets the display name for the member as designated by the .
Gets the validation attributes for this member.
An array of validation attributes to apply to this member.
Indicates that a type is validatable to support discovery by the
validations generator.
Contains validation information for a type.
Creates a new instance of .
The type being validated.
The members that can be validated.
Gets the validation attributes for this member.
An array of validation attributes to apply to this member.
The type being validated.
The members that can be validated.
Represents the context for validating a validatable object.
Gets or sets the validation context used for validating objects that implement or have .
This context provides access to service provider and other validation metadata.
This property should be set by the consumer of the
interface to provide the necessary context for validation. The object should be initialized
with the current object being validated, the display name, and the service provider to support
the complete set of validation scenarios.
var validationContext = new ValidationContext(objectToValidate, serviceProvider, items);
var validationOptions = serviceProvider.GetService<IOptions<ValidationOptions>>()?.Value;
var validateContext = new ValidateContext
{
ValidationContext = validationContext,
ValidationOptions = validationOptions
};
Gets or sets the prefix used to identify the current object being validated in a complex object graph.
This is used to build property paths in validation error messages (e.g., "Customer.Address.Street").
Gets or sets the validation options that control validation behavior,
including validation depth limits and resolver registration.
Gets or sets the dictionary of validation errors collected during validation.
Keys are property names or paths, and values are arrays of error messages.
In the default implementation, this dictionary is initialized when the first error is added.
Gets or sets the current depth in the validation hierarchy.
This is used to prevent stack overflows from circular references.
Optional event raised when a validation error is reported.
Represents the context of a validation error.
Gets the name of the property or parameter that caused the validation error.
Gets the full path from the root object to the property or parameter that caused the validation error.
Gets the list of error messages associated with the validation error.
Gets a reference to the container object of the validated property.
Provides configuration options for the validation system.
Gets the list of resolvers that provide validation metadata for types and parameters.
Resolvers are processed in order, with the first resolver providing a non-null result being used.
Source-generated resolvers are typically inserted at the beginning of this list
to ensure they are checked before any runtime-based resolvers.
Gets or sets the maximum depth for validation of nested objects.
This prevents stack overflows from circular references or extremely deep object graphs.
Default value is 32.
Attempts to get validation information for the specified type.
The type to get validation information for.
When this method returns, contains the validation information for the specified type,
if the type was found; otherwise, null.
true if validation information was found for the specified type; otherwise, false.
Attempts to get validation information for the specified parameter.
The parameter to get validation information for.
When this method returns, contains the validation information for the specified parameter,
if validation information was found; otherwise, null.
true if validation information was found for the specified parameter; otherwise, false.
Extension methods for adding validation services.
Adds the validation services to the specified .
The to add the services to.
An optional action to configure the .
The for chaining.
