C#中的Linq to Xml

1：生成XML

public static void CreateElement(string XmlPath)
        {
            XDocument xdoc =
            new XDocument(
                        new XDeclaration("1.0", "utf-8", ""),
                        new XElement("SimulationSettings", 
                                    new XElement("DevBunkerArr", 
                                                new XElement("DevBunkerSettings",
                                                                 new XElement("ID", "B1000"),
                                                                 new XElement("Delivery", "10"),
                                                                 new XElement("Capacity", "5000")
                                                             ),
                                                new XElement("DevBunkerSettings",
                                                                 new XElement("ID", "B1100"),
                                                                 new XElement("Delivery", "10"),
                                                                 new XElement("Capacity", "5000")
                                                             )
                                                ),
                                    new XElement("DevConveyArr",                                         //皮带
                                                new XElement("DevConveySettings",
                                                                 new XElement("ID", "C1000"),
                                                                 new XElement("Delivery", "35"),
                                                                 new XElement("RatedSpeed", "2.0"),
                                                                 new XElement("Length", "40"),
                                                                 new XElement("StartingTime", "10"),
                                                                 new XElement("StoppingTime", "2"),
                                                                 new XElement("SectionNum", "10")
                                                             ),
                                                new XElement("DevConveySettings",
                                                                 new XElement("ID", "C1001"),
                                                                 new XElement("Delivery", "35"),
                                                                 new XElement("RatedSpeed", "2.0"),
                                                                 new XElement("Length", "60"),
                                                                 new XElement("StartingTime", "10"),
                                                                 new XElement("StoppingTime", "2"),
                                                                 new XElement("SectionNum", "10")
                                                             )
                                                )
                                    )
                          );
            xdoc.Save(XmlPath);
        }

2：查询特定节点

public static void QueryDevBunkerArr(string XmlPath, string ID)
        {
            //定义并从xml文件中加载节点（根节点）
            XElement rootNode = XElement.Load(XmlPath);

            //查询语句: 获取节点
            IEnumerable<XElement> myTargetNodes = from myTarget in rootNode.Descendants("DevBunkerSettings")
                                                  where myTarget.Element("ID").Value == ID
                                                  select myTarget;
            foreach (XElement node in myTargetNodes)
            {
                Console.WriteLine("ID = {0}", node.Element("ID").Value);
                Console.WriteLine("Delivery = {0}", node.Element("Delivery").Value);
                Console.WriteLine("Capacity = {0}", node.Element("Capacity").Value);
            }
        }

3：删除节点、

public static void DeleteDevBunkerArr(string XmlPath, string ID)
        {

            //定义并从xml文件中加载节点（根节点）
            XElement rootNode = XElement.Load(XmlPath);

            //查询语句: 获取节点
            IEnumerable<XElement> myTargetNodes = from myTarget in rootNode.Descendants("DevBunkerSettings")
                                                  where myTarget.Element("ID").Value == ID
                                                  select myTarget;

            myTargetNodes.Remove();
            rootNode.Save(XmlPath);
        }

4：修改节点

public static void ModifyDevBunkerArr(string XmlPath, string ID)
        {
            //定义并从xml文件中加载节点（根节点）
            XElement rootNode = XElement.Load(XmlPath);



            //查询语句: 获取节点
            IEnumerable<XElement> myTargetNodes = from myTarget in rootNode.Descendants("DevBunkerSettings")
                                                  where myTarget.Element("ID").Value == ID
                                                  select myTarget;

            //修改 "Capacity"节点
            foreach (XElement node in myTargetNodes)
            {
                node.Element("Capacity").SetValue(1);
            }
            rootNode.Save(XmlPath);
        }

5：增加节点，这块还有些疑问，完全搞懂之后再更
