ReferenceConverter Class

Provides a type converter to convert object references to and from other representations.

Namespace:  System.ComponentModel
Assembly:  System (in System.dll)

[HostProtectionAttribute(SecurityAction.LinkDemand, SharedState = true)]
public class ReferenceConverter : TypeConverter


The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

The ReferenceConverter is typically used within the context of sited components or a design environment. Without a component site or a usable ITypeDescriptorContext, this converter is of little use.

This converter converts a reference of an object that implements the IComponent interface and displays its properties in the Properties window.

For more information about type converters, see the TypeConverter base class and How to: Implement a Type Converter.


You should never create an instance of the ReferenceConverter class. Instead, call the GetConverter method of the TypeDescriptor class. For more information, see the examples in the TypeConverter base class.

This class provides the IsValueAllowed method to check whether a particular value can be added to the standard values collection. If you do not want to add the value to the collection, override this method.

Notes to Inheritors:

Override the IsValueAllowed method when you do not want to add a value to the standard values collection.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
