Read and Write Objects Using Basic Serialization

Certification: Intermediate Level Accuracy: 50% Submissions: 2 Points: 15

Write a C# program to implement a simple serialization system that can save objects to a text file and load them back. Create a serializer class that converts object properties to text format and reconstructs objects from that text.

Example 1
    

  • Input: Create a Product object with Id=101, Name="Laptop", Price=999.99, InStock=true, serialize to file, deserialize back
    • 

  • Output: The deserialized object has the same property values as the original
    • 

  • Explanation: 
      
   
    • Step 1: Create a Product object with specified property values.
      • 
   
    • Step 2: Serialize the object to text format with property:value pairs.
      • 
   
    • Step 3: Save the serialized text to a file.
      • 
   
    • Step 4: Read the text from the file.
      • 
   
    • Step 5: Deserialize the text back into a Product object.
      • 
   
    • Step 6: Verify that the deserialized object has the same property values as the original.
      •

Example 2
    

  • Input: Create a Person object with FirstName="John", LastName="Smith", Age=30, IsEmployed=true, serialize to text, display serialized text, deserialize back
    • 

  • Output: Serialized text shows property:value pairs, deserialized object has same values
    • 

  • Explanation: 
      
   
    • Step 1: Create a Person object with specified property values.
      • 
   
    • Step 2: Serialize the Person object to text format showing each property and its value.
      • 
   
    • Step 3: Display the serialized text to confirm its format.
      • 
   
    • Step 4: Parse the text to recreate a Person object.
      • 
   
    • Step 5: Verify that the recreated object has the same property values as the original.
      •

Constraints
    

  • Your solution should work with public properties only
    • 

  • Support serialization of string, numeric, boolean, and DateTime properties
    • 

  • Time Complexity: O(n) where n is the number of properties in the object
    • 

  • Space Complexity: O(n) for storing the serialized representation

Solution Hints

    
  
  • Use Reflection (System.Reflection namespace) to inspect an object's properties
    • 
  
  • Define a consistent format for the serialized text (e.g., PropertyName:Value with each pair on a new line)
    • 
  
  • Use Type.GetProperties() to get all public properties of an object
    • 
  
  • For deserialization, use Activator.CreateInstance() to create a new instance of the generic type
    • 
  
  • Use appropriate conversion methods (e.g., Convert.ChangeType) when setting property values during deserialization
    •

Steps to solve by this approach:

 Step 1: Define the serialization format (property:value pairs separated by newlines)
 Step 2: Use reflection to iterate through object properties for serialization
 Step 3: Create a string builder to construct the serialized text
 Step 4: For deserialization, parse the text and extract property name-value pairs
 Step 5: Use reflection to set property values on a new object instance
