ExceptionCondition
NotSupportedException

component is a cross-process remoted object.

The properties for a component can differ from the properties of a class, because the site can add or remove properties if the component is sited.

The attributes parameter array is used to filter the array. Filtering is defined by the following rules:

  • If a property does not have an Attribute of the same class, the property is not included in the returned array.

  • If the attribute is an instance of the Attribute class, the property must be an exact match or it is not included in the returned array.

  • If an Attribute instance is specified and it is the default property, it is included in the returned array even if there is no instance of the Attribute in the property.

  • If attributes has a default attribute, the GetProperties method matches the case when the property does not have the attribute applied.

If the component parameter is Nothing, an empty collection is returned.

The order of the returned collection is not guaranteed to be identical between calls, so always order it before use.
