【正文】 t it be easier to create all this functionality once and use it for every language?The .NET Framework Class Library does exactly that. It consists of a vast set of classes designed to satisfy any conceivable programming need. For example, the .NET framework contains classes for handling database access, working with the file system, manipulating text, and generating graphics. In addition, it contains more specialized classes for performing tasks such as working with regular expressions and handling network protocols.The .NET framework, furthermore, contains classes that represent all the basic variable data types such as strings, integers, bytes, characters, and arrays.Most importantly, for purposes of this book, the .NET Framework Class Library contains classes for building pages. You need to understand, however, that you can access any of the .NET framework classes when you are building your pages.Understanding NamespacesAs you might guess, the .NET framework is huge. It contains thousands of classes (over 3,400). Fortunately, the classes are not simply jumbled together. The classes of the .NET framework are organized into a hierarchy of namespaces.ASP Classic NoteIn previous versions of Active Server Pages, you had access to only five standard classes (the Response, Request, Session, Application, and Server objects). , in contrast, provides you with access to over 3,400 classes!A namespace is a logical grouping of classes. For example, all the classes that relate to working with the file system are gathered together into the namespace.The namespaces are organized into a hierarchy (a logical tree). At the root of the tree is the System namespace. This namespace contains all the classes for the base data types, such as strings and arrays. It also contains classes for working with random numbers and dates and times.You can uniquely identify any class in the .NET framework by using the full namespace of the class. For example, to uniquely refer to the class that represents a file system file (the File class), you would use the following: refers to the namespace, and File refers to the particular class.NOTEYou can view all the namespaces of the standard classes in the .NET Framework Class Library by viewing the Reference Documentation for the .NET Framework.Standard NamespacesThe classes contained in a select number of namespaces are available in your pages by default. (You must explicitly import other namespaces.) These default namespaces contain classes that you use most often in your applications:System— Contains all the base data types and other useful classes such as those related to generating random numbers and working with dates an。 } } }}附錄B 英文文獻 and the .NET Framework is part of Microsoft39。 Session[S_key]=。)/script)。 } }} if(!=) { (scriptalert(39。39。)。 (scriptalert(39。 ()。)。,39。,39。,39。,39。,39。,39。,39。,39。,39。,39。,39。 =insert into Users (Utname,Usex,Uage,Unationality,Idname,IdNO,UEmail,Uphone,Uaddress,UQICQ,Uname,Ukey) values(39。 } private void ImageButton1_Click(object sender, e) { Session[S_username]=Session[S_username1].ToString()。 private void Page_Load(object sender, e) { =new SqlConnection([conn])。 private void Page_Load(object sender, e) { =new SqlConnection([conn])。 ()。 SqlDataReader reader=()。++39。 } private void Restype_SelectedIndexChanged(object sender, e) { ()。提交成功！24小時內(nèi)我們將給您回復(fù),請注意查看!39。 ()。 ()。++39。++39。++39。++39。++39。++39。++39。++年++月++日+39。++年++月++日+39。++年++月++日+39。++39。++39。++39。++39。++39。++39。 } private void Button1_Click(object sender, e) { SqlCommand cmd=new SqlCommand(Preconcert,)。 } }}前臺客房預(yù)定部分代碼：namespace HPS{ public class yudingtianxie1 : { SqlConnection 。刪除成功！!39。 ()。++39。 SqlCommand cmd=new SqlCommand(Preconcert,)。/script)。=39。確認成功！39。 ()。++39。預(yù)定成功39。 SqlCommand cmd=new SqlCommand(Preconcert,)。 =reader[5].ToString()。 =reader[16].ToString()。 =reader[13].ToString()。 =reader[6].ToString()。 =reader[2].ToString()。 =reader[4].ToString()。 =reader[10].ToString()。 =reader[7].ToString()。 SqlDataReader reader=()。++39。 } } } private void ren() { ()。 if(Session[fag].ToString()==1) { =false。 if(!IsPostBack) { =Session[id].ToString()。 } } }}后臺定單管理部分代碼：namespace { public class Admin_dingdan : { SqlConnection 。用戶名或密碼錯誤，請重新登陸！39。 ()。)/script)。 } else (scriptalert(39。 Session[S_userpwd]=。 if(()) { Session[Admin_limit]=reader[13].ToString()。 SqlCommand cmd=new SqlCommand(strsql,)。 and Ukey=39。 string strsql=select * from Users where Uname=39。 private void Page_Load(object sender, e) { =new SqlConnection([conn])。另外，感謝在我的畢業(yè)設(shè)計過程中給過我?guī)椭乃型瑢W，是大家的努力才得以完成我的這個預(yù)定系統(tǒng)。在此，感謝我的指導(dǎo)老師張雷老師的指導(dǎo)和督促，在整個的開發(fā)步驟上，張雷老師給我們列出了詳細的工作計劃，使我們在開發(fā)進程上，不致于茫然。致 謝經(jīng)過一個學期的努力，飯店預(yù)定系統(tǒng)的開發(fā)暫時告一段落了。比如客戶與管理員之間的溝通還不夠全面，填寫信息各項的格式（郵件等）自己還不會設(shè)置，客戶的交通沒有得到便捷的服務(wù)（查詢部分機場列車售票情況）等等。當然，由于各方面知識的缺乏，這樣一個系統(tǒng)還遠不夠成熟。數(shù)據(jù)庫經(jīng)過多次修改已逐漸完備。在整個系統(tǒng)開發(fā)過程中遇到了許多的難題，比如兩步注冊操作中，如何使得數(shù)據(jù)庫中的數(shù)據(jù)保持一致；生成樣式這一功能如何實現(xiàn)；應(yīng)該把插入圖片放入到系統(tǒng)路徑的文件夾中，否則在別的機器上無法看到插入圖片；定單分權(quán)限管理；以及指導(dǎo)老師提出的如何使得會員在填寫定單時，可生成部分已知信息；必填項的功能如何實現(xiàn)等等問題。，修改測試: 后臺留言修改點擊更新將原有的回復(fù)信息清除，再進行更新重寫。,添加測試： 后臺資源類型添加填寫添加內(nèi)容，單擊添加按鈕，則添加成功。輸入密碼后需再次輸入，否則提示。測試：輸入用戶名或密碼有誤，則提示“用戶名或密碼錯誤，請重新輸入！”測試：輸入非管理員正確用戶信息，則提示“對不起，您沒有此權(quán)限！” 用戶注冊部分 注冊界面，測試如下：輸入要用戶名與密碼，輸入用戶名已經(jīng)存在，則提示此用戶名已存在。 密碼驗證部分 前臺用戶登錄界面。所以，需求分析、概要設(shè)計、詳細設(shè)計以及程序編碼等各階段所得到的文檔都應(yīng)該是軟件測試的對象[1]。 軟件測試的對象軟件測試不等于程序測試。如果成功的實施了測試，就能夠發(fā)現(xiàn)軟件存在的錯誤[1]。 }8 軟件測試軟件測試的目的是想以最少的時間和人力找出軟件中潛在的錯誤和缺陷。用戶名或密碼錯誤，請重新登陸！39。 ()。)/script)。 } else (scriptalert(39。 Session[S_userpwd]=。if(()) { Session[Admin_limit]=reader[13].ToString()。SqlCommand cmd=new SqlCommand(strsql,)。 and Ukey=39。string strsql=select * from Users where Un
