ValueSerializer Class
Abstract class that defines conversion behavior for serialization from an object representation.
Assembly: System.Xaml (in System.Xaml.dll)
The ValueSerializer type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | CanConvertFromString | When overridden in a derived class, determines whether the specified String can be converted to an instance of the type that the implementation of ValueSerializer supports. |
![]() | CanConvertToString | When overridden in a derived class, determines whether the specified object can be converted into a String. |
![]() | ConvertFromString | When overridden in a derived class, converts a String to an instance of the type that the implementation of ValueSerializer supports. |
![]() | ConvertToString | When overridden in a derived class, converts the specified object to a String. |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetConvertFromException | Returns an exception to throw when a conversion cannot be performed. |
![]() | GetConvertToException | Returns an exception to throw when a conversion cannot be performed. |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() ![]() | GetSerializerFor(PropertyDescriptor) | Gets the ValueSerializer declared for a property, by passing a CLR property descriptor for the property. |
![]() ![]() | GetSerializerFor(Type) | Gets the ValueSerializer declared for the specified type. |
![]() ![]() | GetSerializerFor(PropertyDescriptor, IValueSerializerContext) | Gets the ValueSerializer declared for the specified property, using the specified context. |
![]() ![]() | GetSerializerFor(Type, IValueSerializerContext) | Gets the ValueSerializer declared for the specified type, using the specified context. |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
![]() | TypeReferences | Gets an enumeration of the types referenced by the ValueSerializer. |
The string a converter returns for serialization must be loss-less and the converter must always return the same string for a particular value. If a type converter (derived from TypeConverter) does not meet these requirements in its ConvertTo implementations for string output, a custom ValueSerializer must be declared. Either the ValueSerializer should meet the requirements, or a null ValueSerializer should be associated with the type. A ValueSerializer is associated with a type by applying the ValueSerializerAttribute attribute.
A null ValueSerializer indicates the type converter should be ignored for convert-to-string conversions from the object graph.

Implementation of ValueSerializer should avoid throwing exceptions. Any exceptions thrown could terminate serialization. |
IValueSerializerContext for a ValueSerializer and its APIs is analogous to ITypeDescriptorContext for a TypeConverter. In fact, IValueSerializerContext inherits ITypeDescriptorContext. When a ValueSerializer derived class API is called, the caller (typically a serializer process) passes a context that may provide certain services. Because of the general guidance that a ValueSerializer must not throw exceptions. Failure to return a particular service from the context must also not throw any exceptions.
In previous versions of the .NET Framework, this class existed in the WPF-specific assembly WindowsBase. In .NET Framework version 4, ValueSerializer is in the System.Xaml assembly. For more information, see Types Migrated from WPF to System.Xaml.
