c# - 创建自定义配置

Question

我创建了一个客户配置类 Reports。然后我创建了另一个名为“ReportsCollection”的类。当我尝试执行“ConfigurationManager.GetSection()”时，它不会填充我的集合变量。任何人都可以看到我的代码中的任何错误吗？

这是集合类:

public class ReportsCollection : ConfigurationElementCollection
{
    public ReportsCollection()
    {
    }

    protected override ConfigurationElement CreateNewElement()
    {
        throw new NotImplementedException();
    }

    protected override ConfigurationElement CreateNewElement(string elementName)
    {
        return base.CreateNewElement(elementName);
    }

    protected override object GetElementKey(ConfigurationElement element)
    {
        throw new NotImplementedException();
    }

    public Report this[int index]
    {
        get { return (Report)BaseGet(index); }
    }
}

这是报告类:

public class Report : ConfigurationSection
{
    [ConfigurationProperty("reportName", IsRequired = true)]
    public string ReportName
    {
        get { return (string)this["reportName"]; }
        //set { this["reportName"] = value; }
    }

    [ConfigurationProperty("storedProcedures", IsRequired = true)]
    public StoredProceduresCollection StoredProcedures
    {
        get { return (StoredProceduresCollection)this["storedProcedures"]; }
    }

    [ConfigurationProperty("parameters", IsRequired = false)]
    public ParametersCollection Parameters
    {
        get { return (ParametersCollection)this["parameters"]; }
    }

    [ConfigurationProperty("saveLocation", IsRequired = true)]
    public string SaveLocation
    {
        get { return (string)this["saveLocation"]; }
    }

    [ConfigurationProperty("recipients", IsRequired = true)]
    public RecipientsCollection Recipients
    {
        get { return (RecipientsCollection)this["recipients"]; }
    }
}

public class StoredProcedure : ConfigurationElement
{
    [ConfigurationProperty("storedProcedureName", IsRequired = true)]
    public string StoredProcedureName
    {
        get { return (string)this["storedProcedureName"]; }
    }
}

public class StoredProceduresCollection : ConfigurationElementCollection
{
    protected override ConfigurationElement CreateNewElement()
    {
        throw new NotImplementedException();
    }

    protected override ConfigurationElement CreateNewElement(string elementName)
    {
        return base.CreateNewElement(elementName);
    }

    protected override object GetElementKey(ConfigurationElement element)
    {
        throw new NotImplementedException();
    }

    public StoredProcedure this[int index]
    {
        get { return (StoredProcedure)base.BaseGet(index); }
    }
}
}

下面是创建变量的非常直接的代码:

ReportsCollection reportsCollection = (ReportsCollection) System.Configuration.ConfigurationManager.GetSection("ReportGroup");

编辑添加了 App.Config

<configSections>
<sectionGroup name="ReportGroup">
  <section name="Reports" type="ReportsGenerator.ReportsCollection"/>
</sectionGroup>
</configSections>
<ReportGroup>
<Reports name="DailyIssues" SaveLocation="">
  <StoredProcedures>
    <add StoredProcedureName="RPTDailyIssues" />
    <add StoredProcedureName="RPTNoIssues" />
  </StoredProcedures>
  <Parameters>
    <add ParameterName="@FromDate" />
    <add ParameterName="@ThruDate" />
  </Parameters>
  <Recipients>
    <add RecipientName="me@mycompany.com"
  </Recipients>
</Reports>
</ReportGroup>

您应该查看 Jon Rista 在 CodeProject 上关于 .NET 2.0 配置的三部分系列。

• Unraveling the mysteries of .NET 2.0 configuration
• Decoding the mysteries of .NET 2.0 configuration
• Cracking the mysteries of .NET 2.0 configuration

强烈推荐，写得很好，非常有帮助!

此外，还有一个 Configuration Section Designer Visual Studio 插件，对创建自定义配置部分非常有帮助 - 它具有可视化设计器，可在后台创建所有必要的 XSD 和类。
