我的网络文件夹中有profile.xml
个文件:
<?xml version="1.0" encoding="utf-8"?>
<myXML>
<RealName>Nguyen Van A</RealName>
<Email>vyclarks@gmail.com</Email>
<Phone>2165421</Phone>
<Address>Ho Chi Minh</Address>
<Link1>dtvt</Link1>
<Link2></Link2>
<Link3></Link3>
</myXML>
根据建议,我通过以下代码从该文件中获取数据:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Xml.Linq;
public class profile
{
public string realname { get; set; }
public string email { get; set; }
public string phone { get; set; }
public string address { get; set; }
public string link1 { get; set; }
public string link2 { get; set; }
public string link3 { get; set; }
}
public void getProfile()
{
string path = this.Server.MapPath("~/Lecturer/");
string targetPath = path + @"\"+username+"\\profile.xml";
bool isExists = System.IO.Directory.Exists(targetPath);
if(isExists)
{
List<profile> profiles = (
from e in XDocument.Load(targetPath)
.Root.Element("myXML")
select new profile
{
realname = (string) e.Element("RealName"),
email = (string) e.Element("Email"),
phone = (string) e.Element("Phone"),
address = (string) e.Element("Address"),
link1 = (string) e.Element("Link1"),
link2 = (string) e.Element("Link2"),
link3 = (string) e.Element("Link3")
}
).ToList();
}
...//code to get list value...
}
但它有一个错误:Cannot resolve symbol "select"
有没有更好的方法从profile.xml
文件???
答案 0 :(得分:2)
来自e in ... 语句中存在错误。 XDocument.Load(targetPath).Root.Element(“myXML”)只为您返回一个XML元素。所以你不能对单个对象进行linq查询(不要与只包含一个对象的集合混合)。
要使其正常工作,您需要将Element方法更改为Elements:
from e in XDocument.Load(targetPath).Root.Elements("myXML")
select new profile
{
realname = (string) e.Element("RealName"),
email = (string) e.Element("Email"),
phone = (string) e.Element("Phone"),
address = (string) e.Element("Address"),
link1 = (string) e.Element("Link1"),
link2 = (string) e.Element("Link2"),
link3 = (string) e.Element("Link3")
}
<强>更新强> 如果XML文件中只有一个myXML节点(因为它是示例中的根节点),那么根本不需要linq查询。尝试以下一种方式从XML读取数据:
var prof = XDocument.Load(targetPath).Root;
var p = new profile()
{
realname = prof.Element("RealName").Value,
email = prof.Element("Email").Value,
phone = prof.Element("Phone").Value,
address = prof.Element("Address").Value,
link1 = prof.Element("Link1").Value,
link2 = prof.Element("Link2").Value,
link3 = prof.Element("Link3").Value
}
我已经使用您的示例中的XML进行了测试
