This section contains sample abstracts for the C# Tutorials. Each abstract contains links that allow you to open the sample in the development environment and copy the sample source files to your hard drive.
| Sample | Description |
|---|---|
| Hello World | Shows a Hello World application. |
| Command Line Parameters | Shows simple command-line processing; also shows array indexing. |
| Arrays | Shows how to use arrays. |
| Properties | Shows how properties are declared and used; also demonstrates abstract properties. |
| Libraries | Shows how to use compiler options to create a DLL from multiple source files; also, how to use the library in other programs. |
| Versioning | Demonstrates versioning in C# through the use of the override and new keywords. |
| Collection Classes | Shows how to make collection classes that can be used with the foreach statement. |
| Structs | Shows how to use structs in C#. |
| Indexers | Shows how to use array notation to access an object. |

| XML Documentation | Shows how to document code by using XML. |
| Platform Invoke | Shows how to call platform invokes (exported DLL functions) from C#. |
| COM InterOp Part 1 | Shows how to use C# to interoperate with COM objects. |
| COM Interop Part 2 | Shows how to a use a C# server with a C++ COM client. |
| Attributes | Shows how to create custom attribute classes, use them in code, and query them through reflection. |
| Security | Discusses .NET Framework security and shows two ways to modify security permissions in C#: permission classes and permission attributes. |
| Threading | Demonstrates various thread activities such as creating and executing a thread, synchronizing threads, interacting between threads, and using a thread pool. |
| Unsafe Code | Shows how to use pointers. |
| OLE DB | Demonstrates how to use a Microsoft Access database from C#. It shows how you can create a dataset and add tables to it from a database. |
