linq作为一种数据操作技术,它能够将复杂的查询应用简化成一个简单的查询语句,在传统的软件开发中,那些复杂、冗余、难以实现的方法使用linq技术都能很好的解决,极大的方便了开发人员对于业务逻辑的处理代码的编写。linq作为编程语言的一部分,它还弥补了sql语句中的一些不足,在一定的程度上达到防止sql注入式攻击的目的。文中针对linq技术进行研究,结合传统的基于.NET三层架构模型,给出一种基于.NET的linq的三层架构方式。并采用基于linq三层架构对学生信息管理系统加以实现,提高了应用程序的安全性和可移植性。

This paper presents the implementation of CETPayment system which is an online payment system against CET (College English test). Hierarchical design is used to increase the flexibility of the system development. Althrough the workload of system design and implementation increased significantly, it can respond to rapidly changing business needs. Because of the use of hierarchical design, the system can be modified and adjusted quickly when it faced two major adjustments in the business logic. linq to sql is used to make the system development process more automatic and effective, and avoid sql injection attacks. A third-party payment company is chosen to process the payment requests of the candidates. A synchronous Reconciliation strategy is used to solve the problem of "single out". CET-CETPayment system can effectively reduce the work pressure of exam organization and management.

A must-have guide that covers all the new features of Visual Studio 2010 Visual Studio allows you to create and manage programming projects for the Windows platform, and the new 2010 version has undergone a major overhaul comprised of significant changes. Written by an author team of veteran programmers and developers, Professional Visual Studio 2010 gets you quickly up to speed on what you can expect from the newest version of Visual Studio. This book's first section is dedicated to familiarizing you with the core aspects of Visual Studio 2010. Everything you need is contained in the first five chapters, from the IDE structure and layout to the various options and settings you can change to make the user interface synchronize with your own way of doing things. From there, the remainder of the book is broken into 11 parts: Getting Started: In this part, you learn how to take control of your projects and organize them in ways that work with your own style. Digging Deeper: Though the many graphical components of Visual Studio that make a programmer's job easier are discussed in many places throughout this book, you often need help when you're in the process of actually writing code. This part deals with features that support the coding of applications such as IntelliSense, code refactoring, and creating and running unit tests In the latest version of the .NET framework, enhancements were added to support dynamic languages and move towards feature parity between the two primary .NET languages, C# and VB. This part covers changes to these languages, as well as looking at a range of features that will help you write better and more consistent code. Rich Client and Web Applications: For support building everything from Office add-ins to cloud applications, Visual Studio enables you to develop applications for a wide range of platforms. These two parts cover the application platforms that are supported within Visual Studio 2010, including *** and Office, WPF, Silverlig

This book starts by reviewing the overall architecture of .NET in order to give you the background you need to be able to write managed code. After that, the book is divided into a number of sections that cover both the C# language and its application in a variety of areas. Part I: The C# Language: This section gives a good grounding in the C# language itself. This section doesnt presume knowledge of any particular language, although it does assume you are an experienced programmer. You start by looking at C's basic syntax and data types, and then explore the object-oriented features of C# before moving on to look at more advanced C# programming topics. Objects, types, inheritance, generics, arrays, tuples, operators, casts, delegates, lambdas, events, strings, regular expressions, collections, Language Integrated, Query (linq), Dynamic Language Extensions, memory management, pointers, reflection, errors, and exception are all covered in part 1. Part II: Visual Studio: This section looks at the main IDE utilized by C# developers worldwide: Visual Studio 2010. The two chapters in this section look at the best way to use the tool to build applications based on the .NET Framework 4. In addition, this section also focuses on the deployment of your projects. Part III: Foundation: In this section, you look at the principles of programming in the .NET environment. In particular, you look at assemblies, instrumentation, security, threading, tasks, synchronization, localization, ***, networking, interop, XAML, Managed Extensibility Framework, Manipulating Files and the Registry, transactions, how to build Windows services, and how to generate your own libraries as assemblies, among other topics. Part IV: Data: Here, you look at accessing databases with ***, *** Entity Framework, data services. This part also extensively covers support in .NET for XML and on the Windows operating system side, and the .NET features of sql Server 2008. Part V: Presentati

Language Integrated Query (linq), as well as the C# 3.0 and VB 9.0 language extensions to support it, is the most import single new feature of Visual Studio 2008 and the .NET Framework 3.x. linq is Microsoft's first attempt to define a universal query language for a diverse set of in-memory collections of generic objects, entities persisted in relational database tables, and element and attributes of XML documents or fragments, as well as a wide variety of other data types, such as RSS and Atom syndication feeds. Microsoft invested millions of dollars in Anders Hejlsberg and his C# design and development groups to add new features to C# 3.0—such as lambda expressions, anonymous types, and extension methods—specifically to support linq Standard Query Operators (SQOs) and query expressions as a part of the language *** additions to VB 9.0 followed the C# team's lead, but VB's implementation of linq to XML offers a remarkable new addition to the language: XML literals. VB's linq to XML implementation includes XML literals, which treat well-formed XML documents or fragments as part of the VB language, rather than requiring translation of element and attribute names and values from strings to XML DOM nodes and *** book concentrates on hands-on development of practical Windows and Web applications that demonstrate C# and VB programming techniques to bring you up to speed on linq technologies. The first half of the book covers linq Standard Query Operators (SQOs) and the concrete implementations of linq for querying collections that implement generic IEnumerable, IQueryable, or both interfaces. The second half is devoted to the *** Entity Framework, Entity Data Model, Entity sql (esql) and linq to Entities. Most code examples emulate real-world data sources, such as the Northwind sample database running on sql Server 2005 or 2008 Express Edition, and collections derived from its tables. Code examples are C# and VB Windows form or We

This paper describes a web application called E-Commerce According to Hobby. In this application, E-Commerce According to Hobby application contains some different technologies such as RSS so as to be able to get the news of products from an e- commerce web site, linq to sql and *** in order to make a connection with sql Server Database System and compare these two technologies. Thanks to this study, we hope that people who use this application can reach the desired news more easily. Therefore, they can get a chance to get rid of the unrelated news for them. This study aims to increase the user-friendliness to do shopping from a specific e-commerce web site such as EBAY without spending a lot of time in a fast way.
