You are creating a class that performs complex financial calculations.

You are creating a class that performs complex financial calculations. The class contains a
method named GetCurrentRate that retrieves the current interest rate and a variable named
currRate that stores the current interest rate.
You write serialized representations of the class.
You need to write a code segment that updates the currRate variable with the current interest rate
when an instance of the class is deserialized. Which code segment should you use?

A. [OnSerializing]internal void UpdateValue (StreamingContext context) {
    currRate = GetCurrentRate();}
B. [OnSerializing]internal void UpdateValue(SerializationInfo info) {
    info.AddValue(“currentRate”, GetCurrentRate());}
C. [OnDeserializing]internal void UpdateValue(SerializationInfo info) {
    info.AddValue(“currentRate”, GetCurrentRate());}
D. [OnDeserialized]internal void UpdateValue(StreamingContext context) {
    currRate = GetCurrentRate();}

Answer: D
