说明：  The target audience for this book consists of developers with an intermediate to advanced experience level looking to deepen their understanding of ASP.NET and its underlying server control architecture. The example code in this book is written in C#. However, if you are a VB. NET developer, the examples translate pretty easily, as ASP.NET development is language agnostic. The .NET Framework and the ASP.NET object model are what’s important, not the language. If you are a developer in need of learning a particular technique, each major facet of control development is presented with simple example code to highlight that particular topic. For example, if you are looking for information on how to add events to your server controls, or how to understand how events work in ASP.NET, you can drill into that chapter to get the details.
