Welcome to FoxLearn
In this tutorial, I'll show you how to use webcam in c# windows forms application using the AForge.NET library
Open your form designer, then drag Label, Combobox, PictureBox and Button controls from the Visual Studio Toolbox into your form designer
You can design a simple UI that allows you to display images from your webcam into the PictureBox control
To play the demo, you should install the AForge library from the Manage Nuget Packages for your project
AForge.NET is an open source c-sharp framework designed for developers and researchers in the fields of Computer Vision and Artificial Intelligence
image processing, neural networks, genetic algorithms, fuzzy logic, machine learning, robotics, etc.
The AForge.Video library contains interfaces and classes to access different video sources, such as IP video cameras
The library defines types used by other video related libraries from AForge.NET framework
The AForge.Video.DirectShow library contains classes, which allow to access video sources using DirectShow interface
Such as, USB web cameras, capture devices, video files, etc.
First, you need to identify the webcam from your computer, then add the webcam name to the combobox
