C#学习 - 关于XML文件的读写

直接上代码说明Xml读写

1. 写Xml

            XmlDocument myXml = new XmlDocument();
            XmlNode docNode = myXml.CreateXmlDeclaration("1.0", "UTF-8", null);

            myXml.AppendChild(docNode);
            XmlElement rootElem = myXml.CreateElement("Root");
            myXml.AppendChild(rootElem);

            CreateNodeTree(myXml, rootElem, definitions, "Child", "Property");

            myXml.Save(xmlFile);

        static void CreateNodeTree<T>(XmlDocument xmldoc, XmlElement parent, Dictionary<string, Tuple<string,List<T>>> dic, 
            string child_name, string child_value)
        {
            foreach (var avail in dic)
            {
                XmlElement e = xmldoc.CreateElement(child_name);
                e.SetAttribute("Name", avail.Key);
                e.SetAttribute("DisplayName", avail.Value.Item1);

                foreach (var value in avail.Value.Item2)
                {
                    XmlElement e2 = xmldoc.CreateElement(child_value);
                    if (typeof(T) == typeof(string))
                    {
                        e2.InnerText = value as string;
                    }
                    else if (typeof(T) == typeof(Tuple<string,string,string>))
                    {
                        var n = (value as Tuple<string, string, string>).Item1;
                        var d = (value as Tuple<string, string, string>).Item2;
                        var t = (value as Tuple<string, string, string>).Item3;

                        e2.SetAttribute("Name", n);
                        e2.SetAttribute("DisplayName", d);
                        if (enumDefinitions.ContainsKey(t))
                        {
                            e2.SetAttribute("Type", t);
                            foreach (var v in enumDefinitions[t])
                            {
                                XmlElement e3 = xmldoc.CreateElement("Enum-Value");
                                e3.InnerText = v as string;
                                e2.AppendChild(e3);
                            }
                        }
                        else if (stringAvailValues.ContainsKey(n) && t.GetType().Equals(typeof(string)))
                        {
                            e2.SetAttribute("Type", t);
                            e2.SetAttribute("AvailValues", "True");
                            foreach (var v in stringAvailValues[n])
                            {
                                XmlElement e3 = xmldoc.CreateElement("Value");
                                e3.InnerText = v as string;
                                e2.AppendChild(e3);
                            }
                        }
                        else
                        {
                            e2.SetAttribute("Type", t);
                        }

                    }
                    e.AppendChild(e2);
                }
                parent.AppendChild(e);
            }
        }

用到的变量

        static List<Type> customTypes = new List<Type>();
        static Dictionary<string, List<string>> stringAvailValues = new Dictionary<string, List<string>>();
        static Dictionary<string, List<string>> enumDefinitions = new Dictionary<string, List<string>>();
        static Dictionary<string, Tuple<string,List<Tuple<string, string, string>>>> definitions = 
            new Dictionary<string, Tuple<string, List<Tuple<string, string, string>>>>();
