TypeConverter.ConvertFrom Method (ITypeDescriptorContext, CultureInfo, Object)
Converts the given object to the type of this converter, using the specified context and culture information.
Assembly: System (in System.dll)
public virtual object ConvertFrom( ITypeDescriptorContext context, CultureInfo culture, object value )
An ITypeDescriptorContext that provides a format context.
Custom type authors that intend to support a type conversion behavior for XAML typically implement a TypeConverter class that supports behavior from a string. This behavior enables type conversion from the string provided as a XAML attribute value and provides a XAML processor with the support needed to create an object from the string, so that the object can be produced in a parsed object graph. Custom types or members of custom types are indicated by applying TypeConverterAttribute to the definitions, with the attribute referencing the custom TypeConverter implementation.
For XAML purposes, you do not typically provide branching implementations based on culture. This is because XAML is precompiled in a development environment context, and culture-specific information for runtime XAML is not relevant for XAML type conversion. For more information, see Type Converters for XAML Overview.
Notes to Inheritors:
Override this method to provide your own conversion requirements.
Use the context parameter to extract additional information about the environment from which this converter is invoked. This parameter can be null, so always check it. Also, properties on the context object can return null.
