Dynamic way to replicate and manipulate objects in .NET

DynamicPocoProxy

Overview

The DynamicPocoProxy library provides a dynamic way to replicate and manipulate objects in .NET.

It allows for deep and shallow cloning of objects, dynamic property access, and custom value modification through the IValueModifier interface. Additionally, it includes a custom JSON converter for seamless serialization and deserialization of DynamicDataReplica objects.

Comparison

DispatchProxy

DispatchProxy is a .NET class that provides a way to create proxy instances that can intercept method calls. It is part of the .NET framework and is used to create dynamic proxies for interfaces.

• It creates proxies for interfaces by subclassing DispatchProxy.
• It's .NET built in proxy solution.
• It can only intercepts method calls on interfaces.

Castle.Core

Castle.Core is a popular library that provides dynamic proxy capabilities, among other features. It allows for the creation of proxy objects that can intercept method calls and property accesses.

• It uses ProxyGenerator to create proxy objects. It supports interface and class proxies.
• It provides extensive interception capabilities through IInterceptor
• It can proxy virtual properties only.

DynamicPocoProxy

• It can proxy and modify read-only properties.
• It can only proxy properties, not able to proxy methods.
• It leverage the dynamic capability of .NET, you can't cast the replica back to original type.

Usage example

Basic Usage

var target = new { Name = "John", Age = 30 };
dynamic replica = DynamicDataReplica.DeepClone(target);

Console.WriteLine(replica.Name); // Outputs: John
Console.WriteLine(replica.Age);  // Outputs: 30

Accessing nested properties

var target = new { Name = "John", Address = new { City = "New York", Zip = "10001" } };
dynamic replica = DynamicDataReplica.DeepClone(target, true);

Console.WriteLine(replica.Address.City); // Outputs: New York
Console.WriteLine(replica.Address.Zip);  // Outputs: 10001

Updating the property value with Modifier

public class CustomModifier : IValueModifier
{
    public bool TryUpdateValue(string propertyPath, object originalValue, out object? modifiedValue)
    {
        if (propertyPath == "Age")
        {
            modifiedValue = (int)originalValue + 1;
            return true;
        }
        modifiedValue = null;
        return false;
    }
}

var target = new { Name = "John", Age = 30 };
dynamic replica = new DynamicDataReplica(target, true, new CustomModifier());

Console.WriteLine(replica.Name); // Outputs: John
Console.WriteLine(replica.Age);  // Outputs: 31
