CSHARP make plugin (addin) program C # compile plug-in-based programs

In order to make the software more reusable and scalable, the idea of plug-in (plug-in) is put forward, and some excellent foreign programs are written based on this. IE, Firefox, Eclipse, etc... I will not talk much about the specific theoretical knowledge. I have extracted two paragraphs from the Internet .....

 

In computing,Plug-in
(Also:Plugin
,Addin
,Add-in
,Addon
,Add-on
,Snap-in
OrSnapin
; But see alsoExtension
) Consists of a computer program that interacts with a Host application (a Web browser or an email client
, For example) to provide a certain, usually very specific, function "on demand". Often,Add-on
Is considered the general term comprising plugins, extensions, and themes as subcategories^{[Citation needed

Applications Support plugins for collections reasons. Some of the main reasons include:

• To enable third-party developers
  To create capabilities to extend an application
• To support features yet unforeseen
• To reduce the size of an application
• To separate source code from an application because of incompatible software licenses.

Examples of applications and their plug-ins include:

• Microsoft Office uses plug-ins (better known as add-ins) to extend the capabilities of its application by adding commandm commands and specialized features
• Rockbox, a firmware for digital audio players, can use plug-ins, for example: play games, use the text editor
• Email clients
  Use plug-ins to decrypt and encrypt email (Pretty Good Privacy) or to send oversized email attachments (Globalscape Mail Express
  )
• Graphics software use plug-ins to support file formats and process images (Adobe Photoshop)
• Media players
  Use plug-ins to support file formats and apply filters (foobar2000, GStreamer, Quintessential
  , VST, Winamp, XMMS)
• Packet sniffers
  Use plug-ins to decode packet formats (OmniPeek)
• Remote sensing applications use plug-ins to process data from different sensor types (Opticks
  )
• Software development environments use plug-ins to support programming languages
  (Eclipse
  , JEdit, MonoDevelop)
• Web browsers use plug-ins to play video and presentation formats (Flash, QuickTime, Microsoft Silverlight, 3 DMLW)
• Some digital mixing protocols les allow plug-ins to extend features such as reverberation effects, equalization and compression.
• Some Web content management systems use plug-ins to increase functionality.

Basic Principles:

The Host application provides services which the plug-in can use,
Including a way for plug-ins to register themselves with the host
Application and a protocol
For the exchange of data with plug-ins. Plug-ins depend on the services
Provided by the Host application and do not usually work by themselves.
Conversely, the host application operates independently of
Plug-ins, making it possible for end-users to add and update plug-ins
Dynamically without needing to make changes to the Host application.

Open application programming interfaces
(APIS) provide a standard interface, allowing third parties to create
Plug-ins that interact with the Host application. A stable API allows
Third-party plug-ins to continue to function as the original version
Changes and to extend the life-cycle of obsolete applications. The Adobe Photoshop and After Effects plug-in APIs have become a standard^{[Citation needed

And competing applications such as Corel Paint Shop Pro have adopted them to some extent. Other examples of such APIs include Audio Units and VST.}

Games and productivity applications often use plug-in ubuntures
Which allow original and third-party publishers to add functionality.

The Microsoft Flight Simulator series has become well-known for its aircraft add-ons.

Outside software, a network switch may ship with an unoccupied but non-standard port to accommodate various optional physical-layer connectors.

Outside software again, manufacturers can use plug-ins to create vendor lock-in by limiting upgrade options solely to those available from or endorsed by the original manufacturer. IBM's Micro Channel Architecture
, Technically superior to Industry Standard Architecture
As a way to add components to IBM PCs, largely failed to gain wide
Support due to the difficulty in getting certification for third-party
Devices.

Csdn has an introduction to the implementation of the plug-in bolog: http://blog.csdn.net/stella_tangxing/archive/2005/04/28/366850.aspx

 

In my resources, there is a simple program I wrote with CSharp, explaining the specific implementation of the plug-in ..... or mail me to you... please kindly advise .....
