c# - 以 XML 格式存储自定义应用程序设置

Question

请帮忙。我有这段代码，这是我的类来序列化\反序列化应用程序设置。

[XmlRoot("EvaStartupData")]
[Serializable] 
public class MyConfigClass
{
    public string ServerName { get; set; }
    public string Database { get; set; }
    public string UserName { get; set; }
    public string UserLogin { get; set; }


    public static void MyConfigLoad()
    {
        FileInfo fi = new FileInfo(myConfigFileName);
        if (fi.Exists)
        {
            XmlSerializer mySerializer = new XmlSerializer(myConfigClass.GetType());
            StreamReader myXmlReader = new StreamReader(myConfigFileName);
            try
            {

                myConfigClass = (MyConfigClass)mySerializer.Deserialize(myXmlReader);
                myXmlReader.Close();
            }
            catch (Exception e)
            {
                MessageBox.Show("Ошибка сериализации MyConfigLoad\n" + e.Message);
            }

            finally
            {
                myXmlReader.Dispose();
            }
        }
    }

    public static void MyConfigSave()
    {
        XmlSerializer mySerializer = new XmlSerializer(myConfigClass.GetType());
        StreamWriter myXmlWriter = new StreamWriter(myConfigFileName);
        try
        {
            mySerializer.Serialize(myXmlWriter, myConfigClass);
        }
        catch (Exception e)
        {
            MessageBox.Show("Ошибка сериализации MyConfigSave\n" + e.Message);
        }

        finally
        {
            myXmlWriter.Dispose();
        }
    }

}

序列化为我提供了简单的 xml 结构:

<ServerName>navuhodonoser</ServerName>
<Database>matrix</Database>
<UserName>Mr.Smith</UserName>
<UserLogin>neo</UserLogin>

我必须如何修改我的类才能获得此 xml 结构？:

<Connection ServerName="navuhodonoser" Database="matrix" ....>

默认情况下，XmlSerializer 会将所有公共(public)属性序列化为元素；要覆盖它，您需要使用 [XmlAttribute](来自 System.Xml.Serialization 命名空间)标记每个属性，这将为您提供所需的输出。

例如:

[XmlAttribute]
public string ServerName { get; set; }

[XmlAttribute]
public string Database { get; set; }

[XmlElement]
public string UserName { get; set; }

// Note: no attribute
public string UserLogin { get; set; }

会产生类似的东西:

<xml ServerName="Value" Database="Value">
    <UserName>Value</UserName>  <!-- Note that UserName was tagged with XmlElement, which matches the default behavior -->
    <UserLogin>Value</UserLogin>
</xml>
