Visual C# Sample Applications
This topic describes available C# samples.
To access samples from Visual Studio
On the Help menu, click Samples.
In the Samples on Disk section of the readme file, click local Samples folder. By default, the samples are installed in drive:\Program Files\Microsoft Visual Studio 10.0\Samples\1033 or drive:\Program Files (x86)\Microsoft Visual Studio 10.0\Samples\1033.
Right-click the .zip file that contains the samples you want to open and then click Extract All to extract the samples to a folder of your choice.
For the most current samples, see the Visual C# Samples Web site.
Microsoft provides the included samples "AS IS" with no warranties. The code in the samples is provided just to illustrate concepts. The provided code may not meet security requirements for any specific environment. We recommend that you add security and error-handling code to your projects to make them as secure and robust as you deem appropriate.
Demonstrates new features that simplify access to Office API objects. For more information, see How to: Access Office Interop Objects by Using Visual C# 2010 Features (C# Programming Guide).
Shows how to use the dynamic (C# Reference) keyword to enable access to IronPython libraries and objects from C# code.
Demonstrates how to create and use covariant and contravariant generic delegates. For more information, see Variance in Generic Interfaces (C# and Visual Basic) and Variance in Delegates (C# and Visual Basic).
Anonymous Delegates Sample
Demonstrates the use of unnamed delegates to reduce application complexity.
Shows how to use arrays.
Shows how to create custom attribute classes, use them in code, and query them through reflection.
Collection Classes Sample
Shows how to make non-generic collection classes that can be used with the foreach statement.
COM Interop Sample, Part 1
Shows how to use C# to interoperate with COM objects.
COM Interop Sample, Part 2
Shows how to a use a C# server together with a C++ COM client.
Command-Line Parameters Sample
Demonstrates simple command-line processing and array indexing.
Conditional Methods Sample
Demonstrates conditional methods, which provide a powerful mechanism by which calls to methods can be included or omitted depending on whether a symbol is defined.
Shows how delegates are declared, mapped to static and instance methods, and combined into multicast delegates.
Shows how to declare, invoke, and configure events in C#.
Explicit Interface Implementation Sample
Demonstrates how to explicitly implement interface members and how to access those members from interface instances.
Shows how to make generic collection classes that can be used with the foreach statement.
Hello World Sample
A Hello World application.
Shows how C# classes can declare indexers to provide array-like access to objects.
Indexed Properties Sample
Shows how to implement a class that uses indexed properties. Indexed properties enable you to use a class that represents an array-like collection.
Shows how to use compiler options to create a DLL from multiple source files; also, how to use the library in other programs.
Demonstrates value types, such as double and bool, that can be set to null.
OLE DB Sample
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.
Operator Overloading Sample
Shows how user-defined classes can overload operators.
Partial Types Sample
Demonstrates how classes and structures can be defined in multiple C# source-code files.
Platform Invoke Sample
Shows how to call exported DLL functions from C#.
Shows how properties are declared and used; also demonstrates abstract properties.
Discusses .NET Framework security and shows two ways to modify security permissions in C#: using permission classes and permission attributes.
Shows how to use structs in C#.
Demonstrates various thread activities such as creating and executing a thread, synchronizing threads, interacting between threads, and using a thread pool.
Unsafe Code Sample
Shows how to use unmanaged code (code that uses pointers) in C#.
User-Defined Conversions Sample
Shows how to define conversions to and from user-defined types.
Demonstrates versioning in C# by using the override and new keywords.
XML Documentation Sample
Shows how to document code by using XML.
Demonstrates how to use the yield keyword to filter items in a collection.
