XML与字典读写

XML 格式：

<?xml version="1.0" encoding="utf-8"?>
<DictionaryNotes>
  <DictionaryNote name="CFFE-FLOOR-DM">
    <B_IsSuccess>True</B_IsSuccess>
    <LoadTime>2020/3/20 16:21:52</LoadTime>
    <LoadCount>1</LoadCount>
    <ErrorInfo>
    </ErrorInfo>
  </DictionaryNote>
</DictionaryNotes>

字典 格式：

        Dictionary<string, ModelInfo> Dic_ModelInfo = new Dictionary<string, ModelInfo>();

        //ModelInfo
        bool B_IsSuccess = false;
        DateTime LoadTime = DateTime.Now.AddDays(-1);
        int LoadCount = 0;
        string ErrorInfo = "";
        struct ModelInfo
        {
            public bool B_IsSuccess;
            public DateTime LoadTime;
            public int LoadCount;
            public string ErrorInfo;
        }24         ModelInfo Set_ModelInfo(bool b_IsSuccess, DateTime loadTime, int loadCount, string errorInfo)
        {
            ModelInfo MI = new ModelInfo();
            MI.B_IsSuccess = b_IsSuccess;
            MI.LoadTime = loadTime;
            MI.LoadCount = loadCount;
            MI.ErrorInfo = errorInfo;
            return MI;
        }          

字典读取XML：

private void GetXml()
        {  
            Dic_ModelInfo = new Dictionary<string, ModelInfo>();
            if (!File.Exists(XmlFilePath))
            {
                return;
            }

            XDocument doc = XDocument.Load(XmlFilePath);
            foreach (XElement element in doc.Element("DictionaryNotes").Elements())
            {  
                Dic_ModelInfo.Add(element.Attribute("name").Value.ToString(),
                    Set_ModelInfo(
                        bool.Parse(element.Element("B_IsSuccess").Value),
                        DateTime.Parse(element.Element("LoadTime").Value),
                        int.Parse(element.Element("LoadCount").Value),
                        element.Element("ErrorInfo").Value)
                        );
            }
        } 

字典写入XML:

private void SetXml()
        {
            if (File.Exists(XmlFilePath)) { File.Delete(XmlFilePath); } 

            var xmlDoc = new XmlDocument();
            //Create the xml declaration first  
            xmlDoc.AppendChild(xmlDoc.CreateXmlDeclaration("1.0", "utf-8", null));
            //Create the root node and append into doc  
            var el = xmlDoc.CreateElement("DictionaryNotes");
            xmlDoc.AppendChild(el);

            foreach (var item in Dic_ModelInfo)
            { 
                // DictionaryNote  
                XmlElement elementDictionaryNote = xmlDoc.CreateElement("DictionaryNote");  
                XmlAttribute attrID = xmlDoc.CreateAttribute("name");
                attrID.Value = item.Key;
                elementDictionaryNote.Attributes.Append(attrID);
                el.AppendChild(elementDictionaryNote);

                // B_IsSuccess  
                XmlElement elementB_IsSuccess = xmlDoc.CreateElement("B_IsSuccess");
                elementB_IsSuccess.InnerText = item.Value.B_IsSuccess.ToString();
                elementDictionaryNote.AppendChild(elementB_IsSuccess);
                // LoadTime
                XmlElement elementLoadTime = xmlDoc.CreateElement("LoadTime");
                elementLoadTime.InnerText = item.Value.LoadTime.ToString();
                elementDictionaryNote.AppendChild(elementLoadTime);
                // LoadCount
                XmlElement elementLoadCount = xmlDoc.CreateElement("LoadCount");
                elementLoadCount.InnerText = item.Value.LoadCount.ToString();
                elementDictionaryNote.AppendChild(elementLoadCount);
                // ErrorInfo
                XmlElement elementErrorInfo = xmlDoc.CreateElement("ErrorInfo");
                elementErrorInfo.InnerText = item.Value.ErrorInfo;
                elementDictionaryNote.AppendChild(elementErrorInfo); 

            } 
            xmlDoc.Save(XmlFilePath);
    }
