Lily.Configuration(1.0.0.2)使用XML配置应用。

ISimpleConfiguration接口增加了GetValue方法的重载。

Private Overloads Function GetValue(ByVal [assembly] As System.Reflection.Assembly, ByVal key As String, ByVal defaultValue As Object, ByVal remark As String) As Object Implements ComponentFramework.ISimpleConfiguration.GetValue

 

可以对Lily.XMLHelper组件中的Lily.XMLHelper.XmlEntity类支持。

 

下面来看一个简单的示例：

ConfigurationInfo类用于配置文档管理方式，如FTP或LAN。

主要有几个属性：

1. ConnectionString
2. ConnectionType
3. FilePath

首先定义类

Public Class ConfigurationInfo
    Inherits Lily.XMLHelper.XmlEntity

    Private md_ConnectionString As String = String.Empty
    Private md_ConnectionType As String = String.Empty
    Private md_FilePath As String = String.Empty
#End Region

    <Lily.XMLHelper.XMLAttribute("ConnectionString", "ConnectionString", False, True)> _
        Property ConnectionString() As String
        Get
            Return Me.md_ConnectionString
        End Get
        Set(ByVal Value As String)
            Me.md_ConnectionString = Value
        End Set
    End Property

    <Lily.XMLHelper.XMLAttribute("connectiontype", "ConnectionType")> _
        Property ConnectionType() As String
        Get
            Return Me.md_ConnectionType
        End Get
        Set(ByVal Value As String)
            Me.md_ConnectionType = Value
        End Set
    End Property

    <Lily.XMLHelper.XMLAttribute("FilePath", "FilePath")> _
    Property FilePath() As String
        Get

Technorati Tags:

            Return Me.md_FilePath
        End Get
        Set(ByVal Value As String)
            Me.md_FilePath = Value
        End Set
    End Property

End Class

从上面可以看出，主要是通过XMLAttribute来进行描述的。第一个参数是节点的名称，第二个参数是属性的名称。用于反射获取或设置属性的值。

定义好配置类后，可以通过以下方法，获取对象。

c = CType(Lily.ComponentFramework.ComponentManager.SimpleConfiguration.GetValue(System.Reflection.Assembly.GetAssembly(GetType(ConfigurationInfo)), "连接类型", New ConfigurationInfo, "工程项目文件管理连接类型配置"), ConfigurationInfo)

c就是强类型的ConfigurationIfno了。红色部份，为什么要实例化一个对象呢，如果当前系统没有定义，则返回默认的配置对象。
