Namespace: System.Runtime.Serialization
Assembly: mscorlib (in mscorlib.dll)

public void AddValue (
	string name,
	Object value,
	Type type
public void AddValue (
	String name, 
	Object value, 
	Type type
public function AddValue (
	name : String, 
	value : Object, 
	type : Type



The name to associate with the value, so it can be deserialized later.


The value to be serialized. Any children of this object will automatically be serialized.


The Type to associate with the current object. This parameter must always be the type of the object itself or of one of its base classes.

Exception typeCondition


If name or type is a null reference (Nothing in Visual Basic).


A value has already been associated with name.

The assigned type is always the type of the object, or one of its parents.

If two values are added with names that differ only by case, no exception will be thrown. But that is not a recommended practice. (However, adding two values with the exact same name will cause the SerializationException to be thrown.)
