A. windows XP的文件類型的多少種
Windows系統文件類型概覽
大家知道，Windows系統文件按照不同的格式和用途分很多種類，為便於管理和識別，在對文件命名時，是以擴展名加以區分的，即文件名格式為: "主文件名.擴展名"。這樣就可以根據文件的擴展名，判定文件的種類，從而知道其格式和用途。例如：
"文件名1.DOC"的擴展名"DOC"表示本文件是一個"Microsoft word 文檔"，
"文件名2.XLS"的擴展名"XLS"表示本文件是一個"Microsoft Excel 工作表"，
"文件名3.BMP"的擴展名"BMP"表示本文件是一個"BMP格式圖像"，
"文件名4.MP3"的擴展名"MP3"表示本文件是一個"MP3 格式聲音"，
"文件名5.MPEG"的擴展名"MPEG"表示本文件是一個"電影文件(MPEG)"。

B. C# 類文件後綴是什麼
Visual Studio 開發中常見的文件名後綴
用Visual Studio進行開發時項目內會有很多文件，其中常見的文件名後綴及其功能如下：
.sln：解決方案文件，為解決方案資源管理器提供顯示管理文件的圖形介面所需的信息。
.csproj:項目文件，創建應用程序所需的引用、數據連接、文件夾和文件的信息。
.aspx：Web 窗體頁由兩部分組成：視覺元素（HTML、伺服器控制項和靜態文本）和該頁的編程邏輯。Visual Studio 將這兩個組成部分分別存儲在一個單獨的文件中。視覺元素在.aspx 文件中創建。
.ascx：ASP.NET的用戶控制項，是作為一種封裝了特定功能和行為的Web頁面被開發的。一個用戶控制項包含了HTML、代碼和其他Web或者用戶控制項的組合。
.aspx.cs：Web 窗體頁的編程邏輯位於一個單獨的類文件中，該文件稱作代碼隱藏類文件（.aspx.cs）。
.cs： 類模塊代碼文件。業務邏輯處理層的代碼。
.asax：Global.asax 文件是一個可選的文件，該文件包含響應 ASP.NET 或 HTTP 模塊引發的應用程序級別事件（如Session、Application等的操作）的代碼。
.config：網路應用程序中的Web.config文件和Windows應用程序中的app.config向它們所在的目錄和所有子目錄提供配置信息。
.aspx.resx/.resx：資源文件，資源是在邏輯上由應用程序部署的任何非可執行數據。通過在資源文件中存儲數據，無需重新編譯整個應用程序即可更改數據。
.XSD: 在圖形界面下生成的XML文件，用來保存對資料庫的查詢、插入、刪除、更新等方法，可以重復調用。
.pdb:PDB（程序資料庫）文件保持著調試和項目狀態信息，從而可以對程序的調試配置進行增量鏈接。
.suo:解決方案用戶選項,記錄所有將與解決方案建立關聯的選項，以便在每次打開時，它都包含您所做的自定義設置。
.asmx:asmx ：文件包含 WebService 處理指令，並用作 XML Web services 的可定址入口點。
.vsdisco（項目發現）文件 基於 XML 的文件，它包含為 Web 服務提供發現信息的資源的鏈接 (URL)。
.htc:一個HTML文件,包含腳本和定義組件的一系列HTC特定元素.htc提供在腳本中implement組件的機制
.skin: 皮膚文件，用來設置網路應用程序中特定控制項的字體、顏色等顯示信息。
.css: 樣式表文件，用來為網路應用程序設定各種HTML TAG的字體、顏色等顯示信息。
.sitemap: 站點地圖文件，用來設置網路應用程序中所有文件的樹狀站點地圖。
.master文件：母版文件，為網路應用程序設置網頁的統一模板，新網頁可以直接繼承母版文件。
