定製ConfigurationSection與sectionGroup不起作用

試圖訪問ConnectionConfiguration總是返回默認值或0爲整數數據類型。沒有錯誤被拋出，它只是無法獲得每個屬性的值。請幫我解決這個問題。定製ConfigurationSection與sectionGroup不起作用

我在控制檯應用程序的app.config文件如下：

<?xml version="1.0" encoding="utf-8"?> 
<configuration> 
    <configSections> 
    <sectionGroup name="templates" > 
     <section name="connections" type="Test.ConnectionConfiguration, Test" allowLocation="true" allowDefinition="Everywhere"/> 
    </sectionGroup> 
    </configSections> 
    <templates> 
    <connections allowed="true" port="8080"> 
     <internal name="local" size="1344"/> 
     <external name="internet" value="http" /> 
    </connections> 
    </templates> 
</configuration>

提前的類

public class ConnectionConfiguration : ConfigurationSection 
{ 
    [ConfigurationProperty("allowed", IsRequired = true)] 
    public bool Allowed 
    { 
     get 
     { 
      return (bool)this["allowed"]; 
     } 
     set 
     { 
      this["allowed"] = value; 
     } 
    } 

    [ConfigurationProperty("port", IsRequired = true)] 
    public int Port 
    { 
     get { return (int)this["port"]; } 
     set { this["port"] = value; } 
    } 

    [ConfigurationProperty("internal")] 
    public InternalElement Internal 
    { 
     get { return (InternalElement)this["internal"]; } 
     set { this["internal"] = value; } 
    } 

    [ConfigurationProperty("external")] 
    public ExternalElement External 
    { 
     get { return (ExternalElement)this["external"]; } 
     set { this["external"] = value; } 
    } 
} 
public class InternalElement : ConfigurationElement 
{ 
    [ConfigurationProperty("name", DefaultValue = "local", IsRequired = true)] 
    [StringValidator(InvalidCharacters = "[email protected]#$%^&*()[]{}/;'\"|\\", MinLength = 1, MaxLength = 60)] 
    public string Name 
    { 
     get { return (string)this["name"]; } 
     set { this["name"] = value; } 
    } 

    [ConfigurationProperty("size", DefaultValue = "1234", IsRequired = false)] 
    [IntegerValidator(ExcludeRange = false, MaxValue = 6000, MinValue = 1)] 
    public int Size 
    { 
     get { return (int)this["size"]; } 
     set { this["size"] = value; } 
    } 
} 
public class ExternalElement : ConfigurationElement 
{ 
    [ConfigurationProperty("name", DefaultValue = "local", IsRequired = true)] 
    [StringValidator(InvalidCharacters = "[email protected]#$%^&*()[]{}/;'\"|\\", MinLength = 1, MaxLength = 60)] 
    public string Name 
    { 
     get { return (string)this["name"]; } 
     set { this["name"] = value; } 
    } 

    [ConfigurationProperty("value", DefaultValue = "https", IsRequired = false)] 
    public string Value 
    { 
     get { return (string)this["value"]; } 
     set { this["value"] = value; } 
    } 
}

謝謝！

ConnectionConfiguration config = new ConnectionConfiguration(); 
int test = config.Port; // it should be 8080 but it's 0

不幸的是剛剛創建的配置處理器的新實例不會自動與配置數據來填充它。你必須手動閱讀。爲了做到這一點，你可以在ConnectionConfiguration類如添加靜態屬性：

public class ConnectionConfiguration : ConfigurationSection 
{ 
    private static ConnectionConfiguration connections = ConfigurationManager.GetSection("templates/connections") as ConnectionConfiguration; 
    public static ConnectionConfiguration Connections 
    { 
     get 
     { 
      return connections; 
     } 
    } 
// the rest is the same 
}

，並在您的應用程序，你現在可以訪問自定義配置部分是這樣的：

ConnectionConfiguration config = ConnectionConfiguration.Connections; 
int test = config.Port; // it should now be 8080

使用此代碼得到你所=（ConnectionConfiguration）ConfigurationManager.GetSection尋找 `ConnectionConfiguration配置（「模板/連接」一節）;
