该博客介绍了使用Teddy's Aspect Weaver Version 0.6进行AOP编程的一个实例，包括SecurityAspect（在Account.Login前增加安全检查）、MethodSelfIntroduceAspect（展示每个方法调用的上下文信息和参数列表）、LogAllWriteOperationAspect（记录所有写操作的位置）以及DebugBookConstructorCall（记录Book构造函数的调用）。

本范例基于Teddy’s Aspect Weaver Version 0.6，演示一个简单的AOP应用范例，范例中的具体Sample Aspect有：

1. SecurityAspect: Add additional security checking before Account.Login.
2. MethodSelfIntroduceAspect: Each method’s self-introduction – show each calling methods’ context info and argument lists.
3. LogAllWriteOperationAspect: Log all writing operations called positions.
4. DebugBookConstructorCall: Log after Book’s Constructors’ calling.

织入后的运行结果

Calling method: System.Void SampleApp.Logic.Sample::OrderHandleSample()

Begin an order handle process...

Checked addtional security for account login ok!
Calling method: System.Boolean SampleApp.Logic.Account::Login(System.String,System.String)
Arguments: name, pa$$word
Constructor of Book has been called at 'System.Void SampleApp.Logic.Book::.ctor()'
Calling method: System.Void SampleApp.Logic.Book::LoadBook(System.Int32)
Arguments: 2
Constructor of Book has been called at 'System.Void SampleApp.Logic.Book::.ctor()'
Calling method: System.Void SampleApp.Logic.Book::LoadBook(System.Int32)
Arguments: 1
Constructor of Book has been called at 'System.Void SampleApp.Logic.Book::.ctor(System.Int32)'
calling a write method at 'System.Void SampleApp.Logic.Sample::OrderHandleSample()'
Calling method: System.Void SampleApp.Logic.Order::HandleOrder()

The order handle process is finished.

Calling method: System.Void SampleApp.Logic.Sample::BookUpdateSample()

Begin an book update process...

Checked addtional security for account login ok!
Calling method: System.Boolean SampleApp.Logic.Account::Login(System.String,System.String)
Arguments: name, pa$$word
Constructor of Book has been called at 'System.Void SampleApp.Logic.Book::.ctor()'
Calling method: System.Void SampleApp.Logic.Book::LoadBook(System.Int32)
Arguments: 1
Constructor of Book has been called at 'System.Void SampleApp.Logic.Book::.ctor(System.Int32)'
Calling method: System.Void SampleApp.Logic.Book::set_BookName(System.String)
Arguments: updated book name
calling a write method at 'System.Void SampleApp.Logic.Sample::BookUpdateSample()'
Calling method: System.Void SampleApp.Logic.Book::UpdateBook()

The book update process is finished.
