GridView&DetailsView对XML文件增删改

呵呵,不是什么新东西:)最后代码下载。
XML文件:
<?xml version="1.0" standalone="yes"?>
<XmlDataSet>
  
<UserInfo>
    
<Id>1</Id>
    
<Name>赵AX</Name>
  
</UserInfo>
  
<UserInfo>
    
<Id>2</Id>
    
<Name>钱BB</Name>
  
</UserInfo>
  
<UserInfo>
    
<Id>3</Id>
    
<Name>孙CC</Name>
  
</UserInfo>
  
<UserInfo>
    
<Id>4</Id>
    
<Name>李DY</Name>
  
</UserInfo>
  
<UserInfo>
    
<Id>5</Id>
    
<Name>周EF</Name>
  
</UserInfo>
  
<UserInfo>
    
<Id>6</Id>
    
<Name>吴FF</Name>
  
</UserInfo>
  
<UserInfo>
    
<Id>7</Id>
    
<Name>郑GG</Name>
  
</UserInfo>
</XmlDataSet>
