Sample implementation of different common design patterns and useful snippets for future reference. Written in C#

• Decorator pattern
• Observer pattern
• Singleton pattern
• Strategy pattern
• Factory Method Pattern
• Command Pattern
• Adapter Pattern
• Builder Pattern

• Read arguments from Main
• Read console input

I have for the most part written everything in a single .cs file to make it as easy as possible.

To compile and run the strategy pattern example (assumes you have the csc compiler installed and added as a enviroment variable). Go to the correct folder, compile the .cs file to a runnable exe and run the program from the command line.

Compile and run

cd .\strategy\
csc .\strategy-pattern.cs
.\strategy-pattern.exe

Some projects have been made in Visual Studio. One for a simple console application and one xunit project to run test cases.

Test project

cd .\decorator\
dotnet test
