linq To Xml 用法简介

先看实例:

在配置文件中加入:

<add key="SaveXmlPath" value="D:\SaveXml.xml"/>

而后创建一个实全类:

public class SingleResultBE
   {
       public string Id { get; set; }
       public string Operation { get; set; }
   }

实现代码如下:

private void SavelistToxml(List<SingleResultBE> listInsertResult)
{
    string saveName = ConfigurationManager.AppSettings["SaveXmlPath"];
    
    XElement XmlSaveResult =new XElement("SaveResult",
                from entity in HavelistResult
                select new XElement("Result",
                new XAttribute("ID", string.IsNullOrEmpty(entity.Id)?"1":entity.Id),
                new XAttribute("Operation", string.IsNullOrEmpty(entity.Operation) ? "1" : entity.Operation)
                )
                );
    XmlSaveResult.Save(saveName);
}

把一个List<SingleResultBE> 保存到 xml文件中.

读取:

private list<SingleResultBE> ReadxmlForList()
        {
         
            string xmlName = ConfigurationManager.AppSettings["SaveXmlPath"];
                 XElement docxml = XElement.Load(xmlName);
                List<SingleResultBE> listHaveInsert = (from entity in docxml.Elements()
                                               select entity).ToList();
             return listHaveInsert;
        }
