Question

为什么如果我保存变量然后加载它们，那么companyName和playerName是这样的：System.Xml.XmlElement，而不是我写的？其他变量工作得很好。我正在努力解决这个问题，所以我非常感谢任何帮助，谢谢。

public void LoadGamePrefs()

    string filepath = "c:/Users/gamePrefs.xml";
    XmlDocument xmlDoc = new XmlDocument();


    if(File.Exists (filepath))

        foreach (XmlNode transformInfo in transformList)
        {
            XmlNodeList transformcontent = transformInfo.ChildNodes;    

            foreach (XmlNode transformItems in transformcontent)
            {                  
                if(transformItems.Name == "firstStart")

问题在于：

XmlElement gamePrefs_playerName = xmlDoc.CreateElement("playerName");
gamePrefs_playerName.InnerText = gamePrefs_playerName.ToString();

您正在通过在对象上调用XmlElement将元素内部文本属性设置为.ToString()类+命名空间。

您的意图不明确，但我假设您需要将InnerText属性设置为playerName变量，而不是XmlElement对象的字符串表示。

XmlElement gamePrefs_companyName = xmlDoc.CreateElement("companyName");
gamePrefs_companyName.InnerText = companyName; 

XmlElement gamePrefs_playerName = xmlDoc.CreateElement("playerName");
gamePrefs_playerName.InnerText = playerName;

请注意，此处ToString();来电是无效的，因为playerName/companyName变量已经显示为来自LoadGamePrefs()

中的代码的字符串

用xml保存字符串
