Enterprise Library Security Quickstart基于Security Application Block, Database Application Block, Caching Application Block, Configuration Application Block, Cryptography Application Block等构建，是所有Quickstart中较复杂的一个。其中，用户、角色、用户角色关系、Profile等等均存放在数据库中。

 

Security Application Block Quick Start应用程序运行界面包括Security Database Management, Authentication, Authorization, Profile, Roles等5个部分。

1. Security Database Management

Security Database Management部分包括用户管理、用户角色关系管理等功能。

如下是增加用户部分代码：

       this.databaseManager.InsertUser(this.credentialsForm.Username, this.credentialsForm.Password);

       this.DisplayDatabaseResults(SR.UserCreatedMessage(this.credentialsForm.Username));

SecurityDatabaseManager.InsertUser()调用Microsoft.Practices.EnterpriseLibrary.Security.Database.UserRoleManage类的InsertUser方法，将用户信息Username/Password插入数据表，方法如下：

              public void InsertUser(string userName, string password)

              {

                     byte[] pwdBytes = SHA1Managed.Create().ComputeHash(ASCIIEncoding.ASCII.GetBytes(password));

                     if (!this.manager.UserExists(userName))

                     {

                            this.manager.CreateUser(userName, pwdBytes);

                     }

              }

如下是Quickstart应用程序中的SecurityDatabaseManager类，该类包含类型UserRoleManager的成员变量manage：

this.manager = new UserRoleManager(DbInstanceName, ConfigurationManager.GetCurrentContext());

SecurityDatabaseManager类提供的方法几乎都是调用Microsoft.Practices.EnterpriseLibrary.Security.Database.UserRoleManager类的方法来实现的，上述2个类的Class Diagram如下所示：

 

Security Database Management中其它功能，如删除用户、用户角色管理（增加用户角色和删除用户角色）等代码类似。
