Recently, I uploaded on GitHub a lot of .NET and C# samples I have created over the years, as part of my presentations and trainings. You can find them here and download them. All the samples are comprised of  few lines of code that do a specific thing, relevant to the sample’s name. Some of the samples are pretty old and have been superceded by new language/framework advancements (e.g. Linq To XML vs XmlReader) but I’ve decided to keep them in case they prove useful to someone. Small description follows for each sample below:

• C# Arguments – demonstrates usage of arguments in C# methods
• Chat with TCP – a chat server and client using the TCP protocol
• Collections – usage of .NET collections
• Complex – usage of operator overloading
• Default Arguments – demo of Parallel.ForEach
• Delegates – usage of delegates in C#
• DirectorySearcher – search directories using the DirectoryInfo class
• DownloadString – WebClient demo
• Events – simple Button.Click event handling
• Exceptions – demo of Thread.Abort
• Extension Methods – C# extension methods
• Fibonacci – recursively calculating the Fibonacci sequence in C# using Func delegate
• FileReaderWriter  – FileStream, StreamReader and StreamWriter demo on how to read and write to a file using C#
• FileSystemWatcher – get notified of file system events (file created, deleted etc.)
• Generics and IO – demo of a generic Dictionary being written and read from a file
• Globalization – using globalization classes to display currencies and date/time information in a variety of countries
• HttpWebRequest – HttpWebRequest demo to connect to an HTTP server
• MD5 Hashing  – MD5 hashing using C#
• MultiplyMatrices – multiply two matrices
• Object Serialization – serialize an object using XmlSerializer class
• Processes enumeration – get processes that are currently running on your machine
• Reflection – use reflection in C# to discover information about unknown types and classes
• Regex and pattern matching – use of regular expressions in C#
• SendMail – how to send e-mail using C#
• StopWatch – using a stopwatch in C# to count passing time
• StringBuilder – an efficient class for heavy string manipulation
• Threading – how to use threads in C# using classes in the System.Threading namespace
