根据xml文件名获取xml数据并转化为实体。

1.定义一个xml文件。

<?xml version="1.0" encoding="utf-8" ?>
<UserManager xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" >
  <User>
    <UserName>王三</UserName>
    <Age>18</Age>
    <Gender>male</Gender>
  </User>
  <User>
    <UserName>李四</UserName>
    <Age>18</Age>
    <Gender>male</Gender>
  </User>
  <User>
    <UserName>王五</UserName>
    <Age>18</Age>
    <Gender>male</Gender>
  </User>
</UserManager>

2.定义Helper类。

 public class NickZHao
    {
        public static string GetXmlPath(string XmlName)
        {
            string filePath = string.Empty;
            filePath = System.Web.HttpContext.Current.Server.MapPath(string.Concat("", XmlName+".xml"));

            return filePath;
        }

        public static List<T> XmlToEntityList<T>(string XmlName)
        {
            string xmlPath = GetXmlPath(XmlName);
            XmlSerializer serializer = new XmlSerializer(typeof(List<T>));
            Object obj = new Object();

            if (File.Exists(xmlPath))
            {
                using (StreamReader reader = new StreamReader(xmlPath))
                {
                    try
                    {
                        obj = serializer.Deserialize(reader);
                    }
                    catch (Exception ex)
                    {
                        //Here put your code witch dealing with exception
                    }
                }
            }
            return (List<T>)obj;
        }

        public static T XmlToEntity<T>(string XmlName)
        {
            string xmlPath = GetXmlPath(XmlName);
            XmlSerializer serializer = new XmlSerializer(typeof(T));
            Object obj = new Object();

            if (File.Exists(xmlPath))
            {
                using (StreamReader reader = new StreamReader(xmlPath))
                {
                     try
                    {
                        obj = serializer.Deserialize(reader);
                    }
                     catch (Exception ex)
                     {
                         //Here put your code witch dealing with exception
                     }
                }
            }
            return (T)obj;
        }  
    }

3.调用

     UserManager userManager = NickZHao.XmlToEntity<UserManager>("User");

        [XmlRoot(ElementName = "UserManager")]
        public class UserManager 
        {
            [XmlElement(ElementName = "User")]
            public List<User> UserList { get; set; }

        }
        
        public class User
        {
            public string UserName { get; set; }

            public int Age { get; set; }

            public string Gender { get; set; }

        }

注意：在定义实体类是记得标记根节点

[XmlRoot(ElementName = "UserManager")]

和节点元素

[XmlElement(ElementName = "User")]
