推荐答案

首先，"DLL"对于.NET几乎不重要，这仅是文件命名约定.本质上，任何可用作库的都是assembly.

可以同时使用System.Drawing或WPF，但不能同时使用.更准确地说:即使有一个互操作库可以一起使用它们，但对于新开发来说，这是相当人为的；它旨在与某些旧代码互操作.

该主题范围很广，可能需要为每个库编写一些文章来涵盖该主题，因此您可以从以下内容开始:
http ://www.codeproject.com/search.aspx?doctypeid = 1& q =％28％22Web + camera％22 + OR ++ Webcam％29 +％22C％23％22 [ ^ ].

找到一些基本信息后，选择要使用的库并制作第一个简单的工作原型应用程序(可以在几个小时内或一个小时内完成)，如果遇到任何问题，您可以提出更多问题.

First of all, "DLL" is pretty much insignificant to .NET, this is no more than the file naming convention. Essentially, anything which can be used as a library is assembly.

You can use either System.Drawing or WPF, but not both together. More exactly: even though there is an interop library to use them together, it would be quite artificial for new development; it is designed for interoperation with some legacy code.

The topic is pretty wide, it could take writing some article per library to cover the topic, so you can start with this:
http://www.codeproject.com/search.aspx?doctypeid=1&q=%28%22Web+camera%22+OR++Webcam%29+%22C%23%22[^].

After you find some basic information, select the library to use and make the first simple working prototype application (it could be done in matter of few hours or just within one hour), you can ask more questions if you face any problems.
