是否可以从内存中的 XML 字符串加载 .config 文件而不写入文件？

Question

我知道如何使用ConfigurationFileMap 类和ConfigurationManager.OpenMappedMachineConfiguration 从文件中加载Configuration 对象，但是有没有办法只从纯XML 中加载Configuration 对象？

Answer 1

是的。这个帮助类应该允许您从 xml 读取或写入任何对象，包括您的 ConfigurationManager 对象。

public static class XmlUtility
{
    /// <summary>
    /// Serializes an object to an XML string.
    /// </summary>
    public static string ToXML(object Obj)
    {
        Type T = Obj.GetType();
        XmlSerializer xs = new XmlSerializer(T);
        using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
        {
            xs.Serialize(ms, Obj);
            UTF8Encoding ue = new UTF8Encoding();
            return ue.GetString(ms.ToArray());
        }
    }

    /// <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);
        }
    }
}
