new System.ComponentModel.DataAnnotations.ValidationContext : obj * System.Collections.Generic.IDictionary<obj, obj> -> System.ComponentModel.DataAnnotations.ValidationContextPublic Sub New (instance As Object, items As IDictionary(Of Object, Object))Parameters

The object instance to validate. It cannot be null.

An optional set of key/value pairs to make available to consumers.
- Attributes

instance is null.

If items is null, an empty dictionary is created. If items is not null, the set of key/value pairs is copied into a new dictionary, preventing consumers from modifying the original dictionary.

new System.ComponentModel.DataAnnotations.ValidationContext : obj * IServiceProvider * System.Collections.Generic.IDictionary<obj, obj> -> System.ComponentModel.DataAnnotations.ValidationContextPublic Sub New (instance As Object, serviceProvider As IServiceProvider, items As IDictionary(Of Object, Object))Parameters
- instance
- Object
The object to validate. This parameter is required.
- serviceProvider
- IServiceProvider
The object that implements the IServiceProvider interface. This parameter is optional.
- items
- IDictionary<Object,Object>
A dictionary of key/value pairs to make available to the service consumers. This parameter is optional.
- Attributes
Exceptions
instance is null.
Remarks
The serviceProvider parameter represents a service that can be used by the GetService method in order to perform custom validation.
If the items parameter is null, an empty dictionary is created. If the parameter is not null, the set of key/value pairs is copied into a new dictionary, which prevents the service consumers from modifying the original dictionary.
Applies to
ValidationContext(Object, String, IServiceProvider, IDictionary<Object,Object>)
- Source:
- ValidationContext.cs
Constructs a ValidationContext for a given object instance with a displayName, an optional serviceProvider, and an optional property bag of items.
public:
ValidationContext(System::Object ^ instance, System::String ^ displayName, IServiceProvider ^ serviceProvider, System::Collections::Generic::IDictionary<System::Object ^, System::Object ^> ^ items);public ValidationContext(object instance, string displayName, IServiceProvider? serviceProvider, System.Collections.Generic.IDictionary<object,object?>? items);new System.ComponentModel.DataAnnotations.ValidationContext : obj * string * IServiceProvider * System.Collections.Generic.IDictionary<obj, obj> -> System.ComponentModel.DataAnnotations.ValidationContextPublic Sub New (instance As Object, displayName As String, serviceProvider As IServiceProvider, items As IDictionary(Of Object, Object))Parameters
- instance
- Object
The object instance being validated. It cannot be null.
- displayName
- String
The display name associated with the object instance.
- serviceProvider
- IServiceProvider
Optional IServiceProvider to use when GetService(Type) is called.
If it is null, GetService(Type) will always return null.
- items
- IDictionary<Object,Object>
Optional set of key/value pairs to make available to consumers via Items.
If null, an empty dictionary will be created. If not null, the set of key/value pairs will be copied into a new dictionary, preventing consumers from modifying the original dictionary.
Exceptions
When instance is null
Remarks
This constructor is trim-safe because it does not use reflection to resolve the Type of the instance to support setting the DisplayName.
