可以说我有一个项目，其中有场（属性）

Lets say I have an item, which has fields(properties)

和我有10-15 项目，我想predefined，或书面的地方，然后加载到code使用其值。

And I have 10-15 items, whose values I want to be predefined, or written somewhere and then loaded into code to be used.

这将是最好的做法呢？

编辑： 这将是常量，刚启动的参数，它不会在应用程序生命周期进行修改。

These would be constants, just start up parameters, which will not be modified during application lifecycle.

您可以序列化和反序列化名单，其中，使用这个辅助类并从XML文件;项目＆GT

You can serialize and deserialize a List<Item> to and from an XML file using this helper class:

public static class XmlHelper
{
    // Specifies whether XML attributes each appear on their own line
    const bool newLineOnAttributes = false;

    public static bool NewLineOnAttributes { get; set; }
    /// <summary>
    /// Serializes an object to an XML string, using the specified namespaces.
    /// </summary>
    public static string ToXml(object obj, XmlSerializerNamespaces ns)
    {
        Type T = obj.GetType();

        var xs = new XmlSerializer(T);
        var ws = new XmlWriterSettings { Indent = true, NewLineOnAttributes = newLineOnAttributes, OmitXmlDeclaration = true };

        var sb = new StringBuilder();
        using (XmlWriter writer = XmlWriter.Create(sb, ws))
        {
            xs.Serialize(writer, obj, ns);
        }
        return sb.ToString();
    }

    /// <summary>
    /// Serializes an object to an XML string.
    /// </summary>
    public static string ToXml(object obj)
    {
        var ns = new XmlSerializerNamespaces();
        ns.Add("", "");
        return ToXml(obj, ns);
    }

    /// <summary>
    /// Deserializes an object from an XML string.
    /// </summary>
    public static T FromXml<T>(string xml)
    {
        XmlSerializer xs = new XmlSerializer(typeof(T));
        using (StringReader sr = new StringReader(xml))
        {
            return (T)xs.Deserialize(sr);
        }
    }

    /// <summary>
    /// Serializes an object to an XML file.
    /// </summary>
    public static void ToXmlFile(Object obj, string filePath)
    {
        var xs = new XmlSerializer(obj.GetType());
        var ns = new XmlSerializerNamespaces();
        var ws = new XmlWriterSettings { Indent = true, NewLineOnAttributes = NewLineOnAttributes, OmitXmlDeclaration = true };
        ns.Add("", "");

        using (XmlWriter writer = XmlWriter.Create(filePath, ws))
        {
            xs.Serialize(writer, obj);
        }
    }

    /// <summary>
    /// Deserializes an object from an XML file.
    /// </summary>
    public static T FromXmlFile<T>(string filePath)
    {
        StreamReader sr = new StreamReader(filePath);
        try
        {
            var result = FromXml<T>(sr.ReadToEnd());
            return result;
        }
        catch (Exception e)
        {
            throw new Exception(e.InnerException.Message);
        }
        finally
        {
            sr.Close();
        }
    }
}

用法：

XmlHelper.ToXmlFile(myList, @"c:\folder\file.xml");

var list = XmlHelper.FromXmlFile<List<Item>>(@"c:\folder\file.xml");
