2、 系统持久化配置信息

配置PersistenceProperty，对于Web应用系统，可以在Global.asax中配置，对于Windows应用程序，可以在程序初始化时设置。

下面是设置的一个例子：

PersistenceProperty pp=new PersistenceProperty();

pp.ConnectionString="server=127.0.0.1;uid=sa;pwd=;database=logisticsDemo;";//数据库连接字符串

pp.DatabaseType=DatabaseType.MSSQLServer; //数据库类型

pp.MapFileLocation=@"WebsharpTestLib,WebsharpTestLib.xml"; //XML定义文件的路径

pp.MapFileLocationTye=MapFileLocationType.Assembly; //XML文件路径的类型

pp.UserID="sa"; //数据库用户名，必须与数据库连接字符串中的用户名一致

pp.Password=""; //数据库用户密码，必须与数据库连接字符串中的用户密码一致

ApplicationConfiguration.DefaultPersistenceProperty=pp; //设置应用程序的默认配置属性

配置信息的说明如下：

1） 数据库连接字符串、用户名和密码的设置按照常规设置

2） MapFileLocationTye指明XML映射文件的路径类型，可以有三种类型:

a) AbsolutePath：采用绝对路径的形式，在这种情况下，MapFileLocation设置成绝对路径的形式，如：“d:\apppath\xml”。

b) VirtualPath：对于Web应用程序，可以设置为虚拟路径的形式，如“/MyWebApp/EntityDefinitions/”。

c) Assembly：XML文件作为资源文件被编译。采用这种形式，需要将XML文件的生成操作属性设置成“嵌入的资源”，这种情况下，MapFileLocation的格式为：“AssemblyName,NameSpace”。例如，XML文件位于WebsharpTestLib项目的xml文件夹下面，MapFileLocation可以设置为：“WebsharpTestLib,WebsharpTestLib.xml”
