【正文】 s properties and content in the visual design tool. Introduction to the C Language and the .NET Framework C is an elegant and typesafe objectoriented language that enables developers to build a wide range of secure and robust applications that run on the .NET Framework. You can use C to create traditional Windows client applications, XML Web services, distributed ponents, clientserver applications, database applications, and much, much more. Microsoft Visual C 2021 provides an advanced code editor, convenient user interface designers, integrated debugger, and many other tools to facilitate rapid application development based on version of the C language and the .NET Framework. Note The Visual C documentation assumes that you have an understanding of basic programming concepts. If you are a plete beginner, you might want to explore Visual C Express Edition, which is available on the Web. You can also take advantage of any of several excellent books and Web resources on C to learn practical programming skills. 18 C syntax is highly expressive, yet with less than 90 keywords, it is also simple and easy to learn. The curlybrace syntax of C will be instantly recognizable to anyone familiar with C, C++ or Java. Developers who know any of these languages are typically able to begin working productively in C within a very short time. C syntax simplifies many of the plexities of C++ while providing powerful features such as nullable value types, enumerations, delegates, anonymous methods and direct memory access, which are not found in Java. C also supports generic methods and types, which provide increased type safety and performance, and iterators, which enable implementers of collection classes to define custom iteration behaviors that are simple to use by client code. As an objectoriented language, C supports the concepts of encapsulation, inheritance and polymorphism. All variables and methods, including the Main method, the application39。 (3) Home design to be reasonable. Home to the first impression left by visitors is important, the design must be attractive in order to have a good visual effect. The contents of the website and function The content of the web site is to be a new, fast, all three sides. The content of the website, including the type of static, dynamic, functional and things to deal with. Website content is determined in accordance with the nature of the site, in the design of the site, mercial websites, popular science site, pany websites, teaching and exchange websites, the content and style are different. We have established websites with the nature of these types of sites are not the same. The structure website (1) site structure。單一程序集可能包含用不同 .NET 語言編寫的多個(gè)模塊，并且類型可以相互引用，就像它們是用同一種語言編寫的。程序集包含清單，它提供關(guān)于程序集的類型、版本、區(qū)域性和安全要求等信息。 C 的生成過程比 C 和 C++ 簡單，比 Java 更為靈活。在 C 中，結(jié)構(gòu)類似于一個(gè)輕量類；它是一種堆棧分配的類型，可以實(shí)現(xiàn)接口，但不支持繼承。了解上述任何一種語言的開發(fā)人員通常在很短的時(shí)間內(nèi)就可以開始使用 C 高效地工作。通過 的基礎(chǔ)結(jié)構(gòu)，您可以響應(yīng)應(yīng)用程序事件并創(chuàng)建自定義 HTTP 處理程序和 HTTP 模塊?？梢哉{(diào)試托管和非托管對象，以及公共語言運(yùn)行庫和腳本語言支持的所有語言。您可以在部署 應(yīng)用程序時(shí)定義配置設(shè)置，并且可以隨時(shí)添加或修訂配置設(shè)置，且對運(yùn)行的 Web 應(yīng)用程序和服務(wù)器具有最小的影響。此外，可以使用 Windows 組或您自己的自定義角色數(shù)據(jù)庫（使用 角色）來管理 Web 應(yīng)用程序的功能和信息方面的授權(quán)。一個(gè)母版頁可以定義您希望應(yīng)用程序中的所有頁（或一組頁）所具有的布局和標(biāo)準(zhǔn)行為。 頁框架為響應(yīng)在服務(wù)器上運(yùn)行的代碼中的客戶端事件提供統(tǒng)一的模型，從而使您不必考慮基于 Web 的應(yīng)用程序中固有的客戶端和服務(wù)器隔離的實(shí)現(xiàn)細(xì)節(jié)。使用這些語言，可以開發(fā)利用公共語言運(yùn)行庫、類型安全、繼承等方面的優(yōu)點(diǎn)的 應(yīng)用程序。這個(gè)階段是網(wǎng)頁的試運(yùn)行期，此時(shí)應(yīng)把網(wǎng)頁的各種缺陷盡量彌補(bǔ)，使網(wǎng)頁更加完善。對于網(wǎng)站的實(shí)現(xiàn)，我認(rèn)為需要考慮兩部分：網(wǎng)頁的實(shí)現(xiàn)； Web 服務(wù)器的實(shí)現(xiàn)。 隨著 Inter 的普及，越來越多的政府部門、公司和個(gè)人意識(shí)到需要擁有自己的獨(dú)立網(wǎng)站。 (3) CSS 在網(wǎng)站中的應(yīng)用事例。版面設(shè)計(jì)是很重要的 ,通過文字、圖形的空間組合 ,能最佳的表達(dá)出和諧與美。網(wǎng)站內(nèi)容的類型包括靜態(tài)的、動(dòng)態(tài)的、功能的和事物處理的。為什么人們會(huì)來到你的網(wǎng)站 ? 你有獨(dú)特的服務(wù)嗎 ? 人們第一次到你的網(wǎng)站是為了什么 ? 他們還會(huì)再來嗎 ? 這些問題都是定義網(wǎng)站時(shí)必須考慮的問題。足不出戶便可以知曉天下大事 ,按幾下鍵盤或點(diǎn)幾下鼠標(biāo)可以與遠(yuǎn)在千里之外的朋友交流 ,網(wǎng)上通信、網(wǎng)上瀏覽、網(wǎng)上交互、網(wǎng)上電子商務(wù)已成為現(xiàn)代人們生活的一部分。要想設(shè)計(jì)美觀實(shí)用的網(wǎng)頁就應(yīng)該深入掌握網(wǎng)站建設(shè)技術(shù)。及時(shí)更新網(wǎng)站內(nèi)容、及時(shí)反饋用戶的要求； （ 3）首頁設(shè)計(jì)要合理。這也就給設(shè)計(jì)者們提出了更高的要求 ,從這個(gè)角度說 ,板式設(shè)計(jì)正是滿足了人們的要求應(yīng)需而生。 (2) CSS 與 HTML 的結(jié)合方式。它深受廣泛用戶的喜愛。系統(tǒng)設(shè)計(jì)是網(wǎng)站具體實(shí)現(xiàn)前的準(zhǔn)備，對網(wǎng)頁的實(shí)現(xiàn)進(jìn)一步提出更具體的要 3 求，對網(wǎng)頁的整體效果、局部細(xì)節(jié)有更明確的設(shè)想。 當(dāng)我們完成了上述工作后，就需要進(jìn)行網(wǎng)頁發(fā)布了。 作為 .NET Framework 的一部分提供 。 支持基于 Web 的設(shè)備（如移動(dòng)電話、手持型計(jì)算機(jī)和個(gè)人數(shù)字助理 (PDA)）的移動(dòng)控件。 頁和控件框架還提供各種功能，以便可以通過主題和外觀來控制網(wǎng)站的整體外觀和感覺。 包括一個(gè)編譯器，該編譯器將包括頁和控件在內(nèi)的所有應(yīng)用程序組件編譯成一個(gè)程序集，之后 宿主環(huán)境可以使用該程序集來處理用戶請求。此信息可以獨(dú)立于頁上的任何控件。使用 運(yùn)行狀況監(jiān)視可以報(bào)告關(guān)鍵事件，這些關(guān) 鍵事件提供有關(guān)應(yīng)用程序的運(yùn)行狀況和錯(cuò)誤情況的信息。因此，用任何語言編寫、使用任何組件模型并在任何操作系統(tǒng)上運(yùn)行的程序，都可以訪問 XML Web services。 Microsoft Visual C 2021 提供高級(jí)代碼編輯器、方便的用戶界面設(shè)計(jì)器、集成調(diào)試器和許多其他工具，以在 C 語言版本 和 .NET Framework 的基礎(chǔ)上加快應(yīng)用程序的開發(fā)。所有的變量和方法，包括 Main 方法（應(yīng)用程序的入口點(diǎn)），都封裝在類定義中。 在 C 中，如果需要與其他 Windows 軟件（如 COM 對象或本機(jī) Win32 DLL）交互，可以通過一個(gè)稱為 “Interop” 的過程來實(shí)現(xiàn)。 CLI 是一種國際標(biāo)準(zhǔn)，是用于創(chuàng)建語言和庫在其中無縫協(xié)同工作的執(zhí)行和開發(fā)環(huán)境的基礎(chǔ)。下圖演示了 C 源代碼文件、基類庫、程序集和 CLR 的編譯時(shí)與運(yùn)行時(shí)的關(guān)系。s lives.

Construction on the site Experience With the popularity of the Inter, more and more government departments, panies and individuals aware of the need to have their own independent Web site. Below on the design and production sites on some of their own experience. After conducting systematic analysis End, we should carry out system design. Web page design similar to the development of software design, topdown, bottomup and continuous updating, and other design methods. The main task is to design the content of the sites, including the website information anization structure, appearance, content block, navigation and links, directory structure design. System design is the site ready before the concrete realization of the website to further the realization of more specific requirements, the overall effect on the website, local details have a clearer idea. This entire process is the key site planning. Next is how to achieve their own Web site design issues. The realization of the
