SerializationInfo.AddValue Method (String, Object)
Adds the specified object into the SerializationInfo store, where it is associated with a specified name.
Assembly: mscorlib (in mscorlib.dll)
The object contained in the value parameter is serialized as the type returned by value.
If two values are added with names that differ only by case, no exception will be thrown, which is not a recommended practice. However, adding two values with the exact same name will cause the SerializationException to be thrown.
