public:
override System::ComponentModel::PropertyDescriptorCollection ^ GetProperties(System::ComponentModel::ITypeDescriptorContext ^ context, System::Object ^ value, cli::array <Attribute ^> ^ attributes);
public override System.ComponentModel.PropertyDescriptorCollection GetProperties (System.ComponentModel.ITypeDescriptorContext context, object value, Attribute[] attributes);
public override System.ComponentModel.PropertyDescriptorCollection? GetProperties (System.ComponentModel.ITypeDescriptorContext? context, object? value, Attribute[]? attributes);
override this.GetProperties : System.ComponentModel.ITypeDescriptorContext * obj * Attribute[] -> System.ComponentModel.PropertyDescriptorCollection
Public Overrides Function GetProperties (context As ITypeDescriptorContext, value As Object, attributes As Attribute()) As PropertyDescriptorCollection
Parameters
- context
- ITypeDescriptorContext
An ITypeDescriptorContext that provides a format context.
Returns
A PropertyDescriptorCollection with the properties that are exposed for an array, or null
if there are no properties.
Remarks
The context
parameter can be used to extract additional information about the environment this converter is being invoked from. This can be null
, so always check. Also, properties on the context object can return null
.
The attributes array will be used to filter the array. The attributes
parameter can specify a mix of Type and Attribute objects. Filtering is defined by the following rules:
A Type will be treated as a wildcard; it will match any property that has the Type in its set of attributes.
If a property does not have an Attribute of the same class, the property will not be included in the returned array.
If the attribute is an instance of Attribute, the property must be an exact match or it will not be included in the returned array.
If an Attribute instance is specified and it is the default property, it will be included in the returned array even if there is no instance of the Attribute in the property.
