NET下XML的读写操作

使用Xml.Linq

XML 格式:

<? xml version="1.0" encoding="utf-8" ?>
< SalaryMap >
   < Salary  unid ="821B26E9FBA51DC9482579CD002811FE"  name ="青岛山东路营业部2012年2月营销人员薪酬申请表" >
     < File >营销人员薪酬申请明细表.xls </ File >
     < SalaryTypeName >01营销人员薪酬申请表 </ SalaryTypeName >
     < SalaryType >1 </ SalaryType >
     < Month >201202 </ Month >
     < BarchID ></ BarchID >
     < BarchName >青岛山东路营业部 </ BarchName >
   </ Salary >

......

</SalaryMap>

 

 

1. 写操作

 

 

private  void SaveXmlMapData(List<SalaryInfo> salaryList)
        {
            XElement root =  new XElement( " SalaryMap "); // XElement.Parse("<SalaryMap></SalaryMap>");
             // var root = doc.Element("SalaryMap");
             foreach ( var item  in salaryList)
            {
                root.Add( new XElement( " Salary ",
                     new XAttribute( " unid ", item.UNID),
                     new XAttribute( " name ", item.Name),
                     new XElement( " File ", item.FileName),
                     new XElement( " SalaryTypeName ",item.SalaryTypeName),
                     new XElement( " SalaryType ", ( int)item.SalaryType),
                     new XElement( " Month ", item.Month),
                     new XElement( " BarchID ", item.BarchID),
                     new XElement( " BarchName ",item.BarchName)
                    ));
            }
            root.Save(SalaryMapFilePath);
        }

 

 

2.读取数据

public List<SalaryInfo> LoadXmlMapData()
        {
            List<SalaryInfo> salaryList =  new List<SalaryInfo>();
             var xmlReader =  new XmlTextReader(SalaryMapFilePath);
             if (xmlReader.ReadToDescendant( " SalaryMap "))
            {
                 var node = XDocument.Parse(xmlReader.ReadOuterXml()).Element( " SalaryMap ").Elements( " Salary ");
                 foreach (XElement item  in node)
                {
                    salaryList.Add( new SalaryInfo()
                    {
                        UNID=item.Attribute( " unid ").Value,
                        Name = item.Attribute( " name ").Value,
                        SalaryType = (SalaryTypeOptions)Enum.Parse( typeof(SalaryTypeOptions), item.Element( " SalaryType ").Value),
                        SalaryTypeName=item.Element( " SalaryTypeName ").Value,
                        FileName=item.Element( " File ").Value,
                        Month = item.Element( " Month ").Value,
                        BarchID = item.Element( " BarchID ").Value,
                        BarchName = item.Element( " BarchName ").Value
                    });
                }
            }
             return salaryList;
        }

 

 

3. 替换/修改/删除 节点值

 

XElement root = XElement.Parse( @"   
                                   <Categories>  
                                      <Category>  
                                        <CategoryID>1</CategoryID>  
                                        <CategoryName>Beverages</CategoryName>  
                                        <Description>Soft drinks, coffees, teas, beers, and ales</Description>  
                                      </Category>  
                                    </Categories>  
                                   ");
             // 替换节点
            root.Element( " Category ").Element( " CategoryID ").ReplaceWith( new XElement( " ID ",  " 2 "));
             // 设置节点值
            root.Element( " Category ").SetElementValue( " CategoryName ",  " test data ");
             // 移除节点
            root.Element( " Category ").Element( " Description ").Remove();
             // 添加节点
            root.Element( " Category ").Element( " CategoryID ").Add( new XElement( " Desc ",  new XCData( " 中文test/ ")));
            Console.WriteLine(root.ToString());
            root.Save( " test.xml ");
