【正文】 for those cases in which direct memory access is absolutely critical. The C build process is simple pared to C and C++ and more flexible than in Java. There are no separate header files, and no requirement that methods and types be declared in a particular order. A C source file may define any number of classes, structs, interfaces, and events. C programs run on the .NET Framework, an integral ponent of Windows that includes a virtual execution system called the mon language runtime (CLR) and a unified set of class libraries. The CLR is Microsoft39。典型的 C 應(yīng)用程序使用 .NET Framework 類庫廣泛地處理常見的 “ 日常 ” 任務(wù)。 C 源文件可以定義任意數(shù)量的類、結(jié)構(gòu)、接口和事件。 C 還支持泛型方法和類型，從而提供了更出色的類型安全和性能。 支持 XML Web services。 始終使用特定的 Windows 標(biāo)識運行，因此，您可以通過使用 Windows 功能（例如 NTFS 訪問控制列表 (ACL)、數(shù)據(jù)庫權(quán)限等等）來保護應(yīng)用程序的安全。 使用 頁和控件框架還可以將常用的 UI 功能封裝成易于使用且可重用的控件。 以上就是建站要大體遵循的七個步驟，這七個步驟是相輔相成的，但可根據(jù)網(wǎng)頁的難易程度和復(fù)雜度適當(dāng)增強或減弱某個環(huán)節(jié)。 在進行完系統(tǒng)分析之后，我們就應(yīng)該進行系統(tǒng)的設(shè)計。在網(wǎng)站的建設(shè)中就應(yīng)用了 CSS 、 javascript 等網(wǎng)頁設(shè)計技術(shù)。其次 ,保持網(wǎng)站的高品質(zhì)。近幾年網(wǎng)頁設(shè)計發(fā)展 ,快得人目不暇接。 網(wǎng)站的結(jié)構(gòu) （ 1）網(wǎng)站的結(jié)構(gòu)； （ 2）定義導(dǎo)航； （ 3）可視化設(shè)計； 2 （ 4）設(shè)計框架和頁面。從而基于 CGI 靜態(tài)的 HTML 頁面將被可提供動態(tài)實時信息 ,并對客戶操作進行反應(yīng)的 Web 頁面的取代。后者則用到各種基于不同操作系統(tǒng)的 Web 服務(wù)器軟件的安裝、調(diào)試。通常，您可以對多個瀏覽器使用相同的頁，因為 會為發(fā)出請求的瀏覽器呈現(xiàn)適當(dāng)?shù)臉?biāo)記。 所有 代碼都經(jīng)過了編譯，可提供強類型、性能優(yōu)化和早期綁定以及其他優(yōu)點。您可以擴展配置方案，使其符合自己的要求。 7 C 是一種簡潔、類型安全的面向?qū)ο蟮恼Z言，開發(fā)人員可 以使用它來構(gòu)建在 .NET Framework 上運行的各種安全、可靠的應(yīng)用程序。 ? 屬性 (Attribute)，提供關(guān)于運行時類型的聲明性元數(shù)據(jù)。 CLR 還提供與自動垃圾回收、異常處理和資源管理有關(guān)的其他服務(wù)。 (4) framework and design pages. 3, Site Design and Implementation With increasing demands on design, high style, highgrade design work before gaining popularity. This also to the designers have put forward higher requirements, from this point of view, the plate design is to meet the requirements of the people should be and Health. The rapid development of science and technology, the Inter into millions of households, also produced a new design space, and a new web design an important part of the field of design. Excellent web design, we must have good creative, so that the audience can be difficult to shift attention long time, produce power. Layout is very important, through text, graphics space portfolio, can best express harmony with the United States. If you want to further understand website design, made separately from other web site39。s loved by extensive user. Many scripting language it is in a relatively good. WWW and effectively achieve the bination of the puter work puting and work blueprint. 12 4. 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 site, I think the need to be considered in two parts: the realization website。下圖演示了 C 源代碼文件、基類庫、程序集和 CLR 的編譯時與運行時的關(guān)系。 在 C 中，如果需要與其他 Windows 軟件（如 COM 對象或本機 Win32 DLL）交互，可以通過一個稱為 “Interop” 的過程來實現(xiàn)。 Microsoft Visual C 2021 提供高級代碼編輯器、方便的用戶界面設(shè)計器、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)。使用 運行狀況監(jiān)視可以報告關(guān)鍵事件，這些關(guān) 鍵事件提供有關(guān)應(yīng)用程序的運行狀況和錯誤情況的信息。 包括一個編譯器，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。 支持基于 Web 的設(shè)備（如移動電話、手持型計算機和個人數(shù)字助理 (PDA)）的移動控件。 當(dāng)我們完成了上述工作后，就需要進行網(wǎng)頁發(fā)布了。它深受廣泛用戶的喜愛。這也就給設(shè)計者們提出了更高的要求 ,從這個角度說 ,板式設(shè)計正是滿足了人們的要求應(yīng)需而生。要想設(shè)計美觀實用的網(wǎng)頁就應(yīng)該深入掌握網(wǎng)站建設(shè)技術(shù)。為什么人們會來到你的網(wǎng)站 ? 你有獨特的服務(wù)嗎 ? 人們第一次到你的網(wǎng)站是為了什么 ? 他們還會再來嗎 ? 這些問題都是定義網(wǎng)站時必須考慮的問題。版面設(shè)計是很重要的 ,通過文字、圖形的空間組合 ,能最佳的表達出和諧與美。 隨著 Inter 的普及，越來越多的政府部門、公司和個人意識到需要擁有自己的獨立網(wǎng)站。這個階段是網(wǎng)頁的試運行期，此時應(yīng)把網(wǎng)頁的各種缺陷盡量彌補，使網(wǎng)頁更加完善。 頁框架為響應(yīng)在服務(wù)器上運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)器隔離的實現(xiàn)細(xì)節(jié)。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)?？梢哉{(diào)試托管和非托管對象，以及公共語言運行庫和腳本語言支持的所有語言。了解上述任何一種語言的開發(fā)人員通常在很短的時間內(nèi)就可以開始使用 C 高效地工作。 C 的生成過程比 C 和 C++ 簡單，比 Java 更為靈活。單一程序集可能包含用不同 .NET 語言編寫的多個模塊，并且類型可以相互引用，就像它們是用同一種語言編寫的。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 J
