C# 应用程序未保存到 xml [关闭]

Question

我是第一次使用 xml，并且一直被它的保存/加载方面所困扰。我希望在应用程序关闭时将文本框中的信息保存到 xml 文件中，但是当应用程序运行时，我无法使用右上角的“X”关闭应用程序。我尝试删除 xml 文件和重新创建它，但这仍然没有帮助。

我现在关闭了应用程序，保存功能确实适用于 xml。然而，加载函数并没有通过它的 foreach 循环将 xml 中的信息添加回应用程序

 XmlDocument xDoc = new XmlDocument();
            xDoc.Load(path + place);
            foreach( XmlNode xNode in xDoc.SelectNodes("ClientMeasurements\\Client"))
            {
                Client c = new Client();

                c.Name = xNode.SelectSingleNode("Name").InnerText;
                c.InitialForearm = xNode.SelectSingleNode("InitialForearm").InnerText;
                c.InitialUpperArmR = xNode.SelectSingleNode("InitialUpperArmRight").InnerText;
                c.InitialUpperArmL = xNode.SelectSingleNode("InitialUpperArmLeft").InnerText;
                c.InitialChest = xNode.SelectSingleNode("InitialChest").InnerText;
                c.InitialWaist = xNode.SelectSingleNode("InitialWaist").InnerText;
                c.InitialHips = xNode.SelectSingleNode("InitialHips").InnerText;
                c.InitialThighR = xNode.SelectSingleNode("InitialThighRight").InnerText;
                c.InitialThighL = xNode.SelectSingleNode("InitialThighLeft").InnerText;
                c.InitialCalfR = xNode.SelectSingleNode("InitialCalfRight").InnerText;
                c.InitialCalfL = xNode.SelectSingleNode("InitialCalfLeft").InnerText;
                c.MostRecentForearm = xNode.SelectSingleNode("MostRecentForearm").InnerText;
                c.MostRecentUpperArmR = xNode.SelectSingleNode("MostRecentUpperArmRight").InnerText;
                c.MostRecentUpperArmL = xNode.SelectSingleNode("MostRecentUpperArmLeft").InnerText;
                c.MostRecentChest = xNode.SelectSingleNode("MostRecentChest").InnerText;
                c.MostRecentWaist = xNode.SelectSingleNode("MostRecentWaist").InnerText;
                c.MostRecentHips = xNode.SelectSingleNode("MostRecentHips").InnerText;
                c.MostRecentThighR = xNode.SelectSingleNode("MostRecentThighRight").InnerText;
                c.MostRecentThighL = xNode.SelectSingleNode("MostRecentThighLeft").InnerText;
                c.MostRecentCalfR = xNode.SelectSingleNode("MostRecentCalfRight").InnerText;
                c.MostRecentCalfL = xNode.SelectSingleNode("MostRecentCalfLeft").InnerText;

                client.Add(c);
                listView1.Items.Add(c.Name);
            }
        }

使用 XML 序列化有一种更简单的方法。

Here 是一篇让您入门的文章。

基本上你想用 [Serializeable] 装饰你的 Client 类，然后使用类似这样的东西从 XML 文件中保存和加载你的 clients 对象（我假设它是某种集合）：

    public static void SerializeObject<T>(T serializableObject, string fileName)
    {
        if (serializableObject == null) { return; }

        try
        {
            XmlDocument xmlDocument = new XmlDocument();
            XmlSerializer serializer = new XmlSerializer(serializableObject.GetType());
            using (MemoryStream stream = new MemoryStream())
            {
                serializer.Serialize(stream, serializableObject);
                stream.Position = 0;
                xmlDocument.Load(stream);
                xmlDocument.Save(fileName);
                stream.Close();
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
            //Log exception here
        }
    }

    public static T DeSerializeObject<T>(string fileName)
    {
        if (string.IsNullOrEmpty(fileName)) { return default(T); }

        T objectOut = default(T);

        try
        {
            string attributeXml = string.Empty;

            XmlDocument xmlDocument = new XmlDocument();
            xmlDocument.Load(fileName);
            string xmlString = xmlDocument.OuterXml;

            using (StringReader read = new StringReader(xmlString))
            {
                Type outType = typeof(T);

                XmlSerializer serializer = new XmlSerializer(outType);
                using (XmlReader reader = new XmlTextReader(read))
                {
                    objectOut = (T)serializer.Deserialize(reader);
                    reader.Close();
                }

                read.Close();
            }
        }
        catch (Exception ex)
        {
            //Log exception here
        }

        return objectOut;
    }
