Methods

	Name	Description
	CanConvertFrom(Type)	Returns whether the type converter can convert an object from the specified type to the type of this converter. (Inherited from TypeConverter.)
	CanConvertFrom(ITypeDescriptorContext, Type)	Determines whether this converter can convert an object of the specified type to the Nullable<T> type (using the Boolean type constraint on the generic). (Overrides TypeConverter.CanConvertFrom(ITypeDescriptorContext, Type).)
	CanConvertTo(Type)	Returns whether the type converter can convert an object to the specified type. (Inherited from TypeConverter.)
	CanConvertTo(ITypeDescriptorContext, Type)	Returns whether the type converter can convert an object to the specified type. (Inherited from TypeConverter.)
	ConvertFrom(Object)	Converts from the specified value to the type of this converter. (Inherited from TypeConverter.)
	ConvertFrom(ITypeDescriptorContext, CultureInfo, Object)	Converts the specified object to a Nullable<T> type (using the Boolean type constraint on the generic). (Overrides TypeConverter.ConvertFrom(ITypeDescriptorContext, CultureInfo, Object).)
	ConvertFromString	Converts the specified text to an object. (Inherited from TypeConverter.)
	ConvertTo(Object, Type)	Converts the specified value object to the specified type. (Inherited from TypeConverter.)
	ConvertTo(ITypeDescriptorContext, CultureInfo, Object, Type)	Converts the specified value object to the specified type. (Inherited from TypeConverter.)
	ConvertToString	Converts the specified object to a string representation. (Inherited from TypeConverter.)
	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 the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	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.)
