Overview

An open source, .NET Standard 1.1 library implementation of the Command Pattern - including reversible commands.

Below are the main features of the library. See the linked code for details.

Please contact me if you have any questions.

Getting Started

NuGet Package Installation

To install the ChannelAdam.Commands NuGet package run the following command in the Package Manager Console:

1PM> Install-Package ChannelAdam.Commands

Usage

An example of the ReversibleCommandManager, using the ExecuteSetPropertyCommand and UndoPreviousCommand methods:

 1var testObject = new ClassWithProperty
 2{
 3    MyProperty = 1
 4};
 5
 6var commandManager = new ReversibleCommandManager();
 7
 8commandManager.ExecuteSetPropertyCommand(testObject, p => p.MyProperty, 100);
 9commandManager.ExecuteSetPropertyCommand(testObject, p => p.MyProperty, 200);
10
11commandManager.UndoPreviousCommand();
12// MyProperty is now back to 100

Reference

• ChannelAdam Logging Library
• ChannelAdam Primitive Extensions Library
• ChannelAdam Reflection Library
• ChannelAdam Transient Fault Handling Library
• ChannelAdam Weak Events Library
• ChannelAdam XML Library

Overview

The open source, full .NET Framework, ChannelAdam Core Library provides some helpful .NET functionality - such as the implementation of various design patterns. This functionality also just happens to be used in the other ChannelAdam code libraries…

Below are the main features of the library. See the linked code for details.
