读xml文档中数据并对其进行排序,然后在datagrid中显示出来

 

1 .新建xml文档(books.xml)
< items >
< item >
     < iname > a </ iname >
     < iid > 1001 </ iid >
     < iamount > 12.34 </ iamount >
</ item >
< item >
     < iname > c </ iname >
     < iid > 002 </ iid >
     < iamount > 15.38 </ iamount >
</ item >
< item >
     < iname > c </ iname >
     < iid > 1280 </ iid >
     < iamount > 18.75 </ iamount >
</ item >
< item >
     < iname > e </ iname >
     < iid > 508 </ iid >
     < iamount > 20.55 </ iamount >
</ item >
</ items >

2 .编写代码
string  dataUrl  =   " books.XML " ;
    
            DataSet ds  =   new  DataSet();
            
            ds.ReadXml(Server.MapPath(dataUrl));

            DataView dv  =   new  DataView(ds.Tables[ 0 ]);
            
            dv.Sort = " iname DESC,iid ASC "  ; // 默认ASC(ascending)

             // DataTable dt = dv.Table;

             this .DataGrid1.DataSource = dv;
             // this.DataGrid1.DataSource=ds.Tables[0];
             this .DataGrid1.DataBind();
