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")]
