说明：  热插拔式应用，winform框架，核心代码，只需要单独开发子系统以dll文件的形式从前台引入即可，供学习用(Hot plug-in applications, WinForm framework, core code, just need to develop a separate subsystem in the form of DLL files from the front desk can be introduced for learning.)

所有程序员都知道应该做单元测试，但为什么你们没有做呢？是因为对单元测试不够了解，还是嫌单元测试麻烦，抑或认为单元测试的投入产出比太低？不管因为什么，你都应该看看这本书。本书在第1版基础上新增了很多内容，不过仍然会手把手地教你从第一个单元测试开始写起，通过简单的例子让你理解如何编写好维护、易明白和可靠的单元测试。在此基础上，本书自然过渡到一些较为高级的主题，比如模拟对象、存根和隔离框架（Moq、FakeItEasy和Typemock Isolator等），同时涉及测试模式，以及组织、重构代码的技巧，乃至怎么测试“不可测试”的代码。另外，其中还介绍了集成测试和关联数据库的测试技术。本书代码示例虽然是用C#写的，但有关单元测试的技术和思想适合所有使用静态类型语言（如VB.NET、Java、C ）的测试人员，以及测试驱动开发人员学习借鉴

.NET TWAIN image scanner(Abstract In Windows imaging applications, the most used API for scanning is TWAIN www.twain.org. Unfortunately, the new .NET Framework has no built-in support for TWAIN. So we have to work with the interop methods of .NET to access this API. This article doesn t explain this interop techniques, and good knowledge of the TWAIN 1.9 specifications is assumed! The sample code included doesn t present a finished library, only some essential steps for a minimal TWAIN adaption to .NET applications. Details First step was to port the most important parts of TWAIN.H, these are found in TwainDefs.cs. The real logic for calling TWAIN is coded in the class Twain, in file TwainLib.cs.. As the TWAIN API is exposed by the Windows DLL, twain_32.dll, we have to use the .NET DllImport mechanism for interop with legacy code. This DLL has the central DSM_Entry(), ordinal#1 function exported as the entry point to TWAIN. This call has numerous parameters, and the last one is of variable type! It was f)
