XML反序列化出错，XML 文档(2, 2)中有错误，不应有 <configuration xmlns=''>。"，详细请进

Question

这是反序列化的代码     
          UpdatePCPwdConfiguration config = new UpdatePCPwdConfiguration();
                XmlSerializer serializer = new XmlSerializer(typeof(UpdatePCPwdCollection));
                FileStream stream = new FileStream(System.IO.Path.GetFullPath("PCIPList.config"), FileMode.Open);
                config = (UpdatePCPwdConfiguration)serializer.Deserialize(stream);
代码应该没有问题，因为以前都这么用，没出错过！
这是XML的Config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <PCConfiguration>
    <pcAddress>
      10.102.12.108
    </pcAddress>
  </PCConfiguration>
</configuration>请各位帮忙看看

Answer 1

UpdatePCPwdConfiguration config = new UpdatePCPwdConfiguration();
XmlSerializer serializer = new XmlSerializer(typeof(UpdatePCPwdCollection));
FileStream stream = new FileStream(System.IO.Path.GetFullPath("PCIPList.config"), FileMode.Open);
config = (UpdatePCPwdConfiguration)serializer.Deserialize(stream); 上面的代码是要把一个Xml文档反序列为一个对象，你的xml文档和对象的属性之间对应出了问题。
把xml文档改为如下应该就ok了：
<?xml version="1.0" encoding="utf-8" ?>
  <PCConfiguration>
    <pcAddress>
      10.102.12.108
    </pcAddress>
  </PCConfiguration>

Answer 2

 [Serializable]
    public class UpdatePCPwdCollection : CollectionBase
    {
        public void Add(UpdatePCPwdEntity updatePCPwd)
        {
            base.List.Add(updatePCPwd);
        }
        [XmlElement]
        public UpdatePCPwdEntity this[int index]
        {
            get
            {
                return (UpdatePCPwdEntity)base.List[index];
            }
            set
            {
                base.List[index] = value;
            }
        }
    }[Serializable, XmlRoot("configuration")]
    public class UpdatePCPwdConfiguration
    {
        private UpdatePCPwdCollection updatePCPwd = new UpdatePCPwdCollection();        [XmlElement("PCConfiguration")]
        public UpdatePCPwdCollection UpdatePCPwd
        {
            get
            {
                return this.updatePCPwd;
            }
            set
            {
                this.updatePCPwd = value;
            }
        }
    }[Serializable]
    public class UpdatePCPwdEntity
    {
        private string pcAddress;        public UpdatePCPwdEntity()
        { }        public UpdatePCPwdEntity(string pcAddress)
        {
            this.pcAddress = pcAddress;
        }        [XmlElement("pcAddress")]
        public string PcAddress
        {
            get { return pcAddress; }
            set { pcAddress = value; }
        }
    }这是序列化的代码

Answer 3

您再看下我序列化的代码是否有问题 
[Serializable]
    public class UpdatePCPwdCollection : CollectionBase
    {
        public void Add(UpdatePCPwdEntity updatePCPwd)
        {
            base.List.Add(updatePCPwd);
        }
        [XmlElement]
        public UpdatePCPwdEntity this[int index]
        {
            get
            {
                return (UpdatePCPwdEntity)base.List[index];
            }
            set
            {
                base.List[index] = value;
            }
        }
    }[Serializable, XmlRoot("configuration")]
    public class UpdatePCPwdConfiguration
    {
        private UpdatePCPwdCollection updatePCPwd = new UpdatePCPwdCollection();        [XmlElement("PCConfiguration")]
        public UpdatePCPwdCollection UpdatePCPwd
        {
            get
            {
                return this.updatePCPwd;
            }
            set
            {
                this.updatePCPwd = value;
            }
        }
    }[Serializable]
    public class UpdatePCPwdEntity
    {
        private string pcAddress;        public UpdatePCPwdEntity()
        { }        public UpdatePCPwdEntity(string pcAddress)
        {
            this.pcAddress = pcAddress;
        }        [XmlElement("pcAddress")]
        public string PcAddress
        {
            get { return pcAddress; }
            set { pcAddress = value; }
        }
    }

Answer 4

xml里面的特殊字符需要用html编码

Answer 5

XmlSerializer serializer = new XmlSerializer(typeof(UpdatePCPwdCollection)); 
改成下面的就可以了.XmlSerializer serializer = new XmlSerializer(typeof(UpdatePCPwdConfiguration));
