C# 自定义配置xml设置并存储到dictionary对象

C# 自定义配置xml设置并存储到dictionary对象,c#,asp.net,xml,web-config,C#,Asp.net,Xml,Web Config,我计划为FormFields、QueryString参数等设置配置键。在我的web.config中,我有如下设置: <WhiteListPaametersGroup> <WhiteListPaameters> <FormField1>EVENTVALIDATION</FormField1> <FormField2>VIEWSTATE</FormField2> <FormField3>B

我计划为FormFields、QueryString参数等设置配置键。在我的web.config中,我有如下设置:

<WhiteListPaametersGroup>
  <WhiteListPaameters>
    <FormField1>EVENTVALIDATION</FormField1>
    <FormField2>VIEWSTATE</FormField2>
    <FormField3>Button1</FormField3>

    <QueryString1>firstname</QueryString1>
    <QueryString2>lastname</QueryString2>

  </WhiteListPaameters>
</WhiteListPaametersGroup>
Dictionary<string, string> parameters = new Dictionary<string,string>();

foreach (XmlNode n in section.ChildNodes)
{
    parameters.Add(n.Name, n.InnerText);
}
<configSections>
    <section name="xslTemplateConfiguration" type="Foo.Web.Applications.CustomConfigurationSections.XslTemplateConfiguration"/>
</configSections>

事件验证
视图状态
按钮1
名字
姓氏
然后在我的代码中,我读取如下值:

<WhiteListPaametersGroup>
  <WhiteListPaameters>
    <FormField1>EVENTVALIDATION</FormField1>
    <FormField2>VIEWSTATE</FormField2>
    <FormField3>Button1</FormField3>

    <QueryString1>firstname</QueryString1>
    <QueryString2>lastname</QueryString2>

  </WhiteListPaameters>
</WhiteListPaametersGroup>
Dictionary<string, string> parameters = new Dictionary<string,string>();

foreach (XmlNode n in section.ChildNodes)
{
    parameters.Add(n.Name, n.InnerText);
}
<configSections>
    <section name="xslTemplateConfiguration" type="Foo.Web.Applications.CustomConfigurationSections.XslTemplateConfiguration"/>
</configSections>
Dictionary参数=新建Dictionary();
foreach(第.ChildNodes节中的XmlNode)
{
添加(n.Name,n.InnerText);
}
有没有更好的储存方法。稍后,我希望能够浏览类似于字典的对象,并能够获取表单字段、查询字符串等的设置

请让我知道我是否可以写得更干净


谢谢

您可以使用XML序列化来存储设置并将其直接还原到对象中。它并不完美,但非常容易设置,并为您提供对象保存/恢复功能

拥有此类(属性必须是公共的):

要将其保存到XML文件,请运行以下代码:

WhiteListParameters parms = new WhiteListParameters
                                {
                                    FormField1 = "EVENTVALIDATION",
                                    FormField2 = "VIEWSTATE",
                                    FormField3 = "Button1",
                                    QueryString1 = "firstname",
                                    QueryString2 = "lastname"
                                };

using(StreamWriter sw = new StreamWriter("C:\\temp\\config.xml"))
{
    XmlSerializer xs = new XmlSerializer(typeof (WhiteListParameters));
    xs.Serialize(sw, parms);
    sw.Close();
}
要将其读回对象,请执行以下操作:

using(StreamReader sr = new StreamReader("c:\\temp\\config.xml"))
{
    XmlSerializer xs = new XmlSerializer(typeof (WhiteListParameters));
    WhiteListParameters parms = (WhiteListParameters) xs.Deserialize(sr);
    sr.Close();
}

您可以研究的一个选项是创建自定义配置部分,您可以在
web.config
中注册该部分

下面是我创建的用于引用XSLT模板的配置部分:

namespace Foo.Web.Applications.CustomConfigurationSections
{
    public class XslTemplateConfiguration : ConfigurationSection
    {
        [ConfigurationProperty("xslTemplates")]
        public XslTemplateElementCollection XslTemplates
        {
            get { return this["xslTemplates"] as XslTemplateElementCollection; }
        }
    }

    public class XslTemplateElement : ConfigurationElement
    {
        [ConfigurationProperty("name", IsRequired = true, IsKey = true)]
        public string Name
        {
            get { return this["name"] as string; }
            set { this["name"] = value; }
        }

        [ConfigurationProperty("path", IsRequired = true)]
        public string Path
        {
            get { return this["path"] as string; }
            set { this["path"] = value; }
        }
    }

    public class XslTemplateElementCollection : ConfigurationElementCollection
    {
        public XslTemplateElement this[object key]
        {
            get { return base.BaseGet(key) as XslTemplateElement; }
        }

        public override ConfigurationElementCollectionType CollectionType
        {
            get { return ConfigurationElementCollectionType.BasicMap; }
        }

        protected override string ElementName
        {
            get { return "xslTemplate"; }
        }

        protected override bool IsElementName(string elementName)
        {
            bool isName = false;
            if (!String.IsNullOrEmpty(elementName))
                isName = elementName.Equals("xslTemplate");
            return isName;
        }

        protected override ConfigurationElement CreateNewElement()
        {
            return new XslTemplateElement();
        }

        protected override object GetElementKey(ConfigurationElement element)
        {
            return ((XslTemplateElement)element).Name;
        }
    }
}
您可以在web.config中注册此部分,如下所示:

<WhiteListPaametersGroup>
  <WhiteListPaameters>
    <FormField1>EVENTVALIDATION</FormField1>
    <FormField2>VIEWSTATE</FormField2>
    <FormField3>Button1</FormField3>

    <QueryString1>firstname</QueryString1>
    <QueryString2>lastname</QueryString2>

  </WhiteListPaameters>
</WhiteListPaametersGroup>
Dictionary<string, string> parameters = new Dictionary<string,string>();

foreach (XmlNode n in section.ChildNodes)
{
    parameters.Add(n.Name, n.InnerText);
}
<configSections>
    <section name="xslTemplateConfiguration" type="Foo.Web.Applications.CustomConfigurationSections.XslTemplateConfiguration"/>
</configSections>

为了读取配置,.NET Framework在命名空间中有许多类。最重要的课程是和。从这些类派生,添加所需的属性并用属性装饰它们。这种方法的优点是类型安全性,可以定义有效值列表,而且.NET Framework会自动从web.config读取、解析和检查所有值。

如果您使用的是vs2010,请看这个扩展,它令人惊讶:
