            SerializeHash dict = SerializeHash.CreateFromFile(filename, false);
            if (dict == null) return false;
            PropertyInfo[] pis = obj.GetType().GetProperties();
            foreach (PropertyInfo pi in pis)
            {
                if (!pi.CanWrite) continue;
                if (pi.GetIndexParameters().Length > 0) continue;
                if (dict.ContainsKey(pi.Name))
                {
                    try
                    {
                        pi.SetValue(obj, dict[pi.Name], null);
                    }
                    catch
                    {
                    }
                }
            }
            return true;
        }
        #endregion
    }

二、定义一个可序列话字典类

/// <summary>
/// 可序列化的字典类，要求包含对像也可序列化
/// </summary>
/// <typeparam name="TKey"></typeparam>
/// <typeparam name="TValue"></typeparam>
   [Serializable()]
	public class SerializableDictionary<TKey, TVal> : Dictionary<TKey, TVal>, IXmlSerializable, ISerializable
	{
		#region Constants
		private const string DictionaryNodeName = "Dictionary";
		private const string ItemNodeName = "Item";
		private const string KeyNodeName = "Key";
		private const string ValueNodeName = "Value";
		#endregion
		#region Constructors
		public SerializableDictionary()
		{
		}

		public SerializableDictionary(IDictionary<TKey, TVal> dictionary)
			: base(dictionary)
		{
		}

		public SerializableDictionary(IEqualityComparer<TKey> comparer)
			: base(comparer)
		{
		}

		public SerializableDictionary(int capacity)
			: base(capacity)
		{
		}

		public SerializableDictionary(IDictionary<TKey, TVal> dictionary, IEqualityComparer<TKey> comparer)
			: base(dictionary, comparer)
		{
		}

		public SerializableDictionary(int capacity, IEqualityComparer<TKey> comparer)
			: base(capacity, comparer)
		{
		}

		#endregion
		#region ISerializable Members

		protected SerializableDictionary(SerializationInfo info, StreamingContext context)
		{
			int itemCount = info.GetInt32("ItemCount");
			for (int i = 0; i < itemCount; i++)
			{
				KeyValuePair<TKey, TVal> kvp = (KeyValuePair<TKey, TVal>)info.GetValue(String.Format("Item{0}", i), typeof(KeyValuePair<TKey, TVal>));
				this.Add(kvp.Key, kvp.Value);
			}
		}

		void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context)
		{
			info.AddValue("ItemCount", this.Count);
			int itemIdx = 0;
			foreach (KeyValuePair<TKey, TVal> kvp in this)
			{
				info.AddValue(String.Format("Item{0}", itemIdx), kvp, typeof(KeyValuePair<TKey, TVal>));
				itemIdx++;
			}
		}

		#endregion
		#region IXmlSerializable Members

		void IXmlSerializable.WriteXml(System.Xml.XmlWriter writer)
		{
			//writer.WriteStartElement(DictionaryNodeName);
			foreach (KeyValuePair<TKey, TVal> kvp in this)
			{
				writer.WriteStartElement(ItemNodeName);
				writer.WriteStartElement(KeyNodeName);
				KeySerializer.Serialize(writer, kvp.Key);
				writer.WriteEndElement();
				writer.WriteStartElement(ValueNodeName);
				ValueSerializer.Serialize(writer, kvp.Value);
				writer.WriteEndElement();
				writer.WriteEndElement();
			}
			//writer.WriteEndElement();
		}

		void IXmlSerializable.ReadXml(System.Xml.XmlReader reader)
		{
			if (reader.IsEmptyElement)
			{
				return;
			}

			// Move past container
			if (!reader.Read())
			{
				throw new XmlException("Error in Deserialization of Dictionary");
			}

			//reader.ReadStartElement(DictionaryNodeName);
			while (reader.NodeType != XmlNodeType.EndElement)
			{
				reader.ReadStartElement(ItemNodeName);
				reader.ReadStartElement(KeyNodeName);
				TKey key = (TKey)KeySerializer.Deserialize(reader);
				reader.ReadEndElement();
				reader.ReadStartElement(ValueNodeName);
				TVal value = (TVal)ValueSerializer.Deserialize(reader);
				reader.ReadEndElement();
				reader.ReadEndElement();
				this.Add(key, value);
				reader.MoveToContent();
			}
			//reader.ReadEndElement();

			reader.ReadEndElement(); // Read End Element to close Read of containing node
		}

		System.Xml.Schema.XmlSchema IXmlSerializable.GetSchema()
		{
			return null;
		}

		#endregion
		#region Private Properties
		protected XmlSerializer ValueSerializer
		{
			get
			{
				if (valueSerializer == null)
				{
					valueSerializer = new XmlSerializer(typeof(TVal));
				}
				return valueSerializer;
			}
		}

		private XmlSerializer KeySerializer
		{
			get
			{
				if (keySerializer == null)
				{
					keySerializer = new XmlSerializer(typeof(TKey));
				}
				return keySerializer;
			}
		}
		#endregion
		#region Private Members
		private XmlSerializer keySerializer = null;
		private XmlSerializer valueSerializer = null;
		#endregion
        public bool SaveToFile(string FileName, bool showException)
        {
           return  SerializeHelper.XMLSerialize(this, FileName, showException);
        }

    }

三、定义可序列序列化实例类

   /// <summary>
    ///  可序列的哈希表,只能通过XML序列化
    /// </summary>
    [Serializable]
   public class SerializeHash : SerializableDictionary<string, object>
    {
        public SerializeHash()
            : base()
        {
        }
        public SerializeHash(IDictionary<string, object> dictionary)
            : base(dictionary)
        {
        }

        public SerializeHash(IEqualityComparer<string> comparer)
            : base(comparer)
        {
        }

        public SerializeHash(int capacity)
            : base(capacity)
        {
        }

        public SerializeHash(IDictionary<string, object> dictionary, IEqualityComparer<string> comparer)
            : base(dictionary, comparer)
        {
        }

        public SerializeHash(int capacity, IEqualityComparer<string> comparer)
            : base(capacity, comparer)
        {
        }

        protected SerializeHash(SerializationInfo info, StreamingContext context)
        {
            int itemCount = info.GetInt32("ItemCount");
            for (int i = 0; i < itemCount; i++)
            {
                KeyValuePair<string, object> kvp = (KeyValuePair<string, object>)info.GetValue(String.Format("Item{0}", i), typeof(KeyValuePair<string, object>));
                this.Add(kvp.Key, kvp.Value);
            }
        }


        /// <summary>
        /// 将内含数据转为对应的类型
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="Name"></param>
        /// <param name="DefaultValue"></param>
        /// <returns></returns>
        public T GetObject<T>(string Name, T DefaultValue)
        {
            if (!this.ContainsKey(Name)) return DefaultValue;
            object obj = this[Name];
            if(!(obj is T)) return DefaultValue;
           return (T)obj;
        }

        public void SetObject(string Name, object Value)
        {
            if (this.ContainsKey(Name)) this[Name] = Value;
            else this.Add(Name, Value);
        }
        public static SerializeHash CreateFromFile(string FileName, bool showException)
        {
            return SerializeHelper.XMLDeSerialize<SerializeHash>(FileName, showException);
        }

        public bool SaveToFile(string FileName, bool showException)
        {
            return SerializeHelper.XMLSerialize(this, FileName, showException);
        }
    }

 四 使用实例：

private static SerializeHash mSystemCachData;

SystemCachData.SetObject("weburl", "www.baidu.com")；

if (mSystemCachData != null)
            {
                mSystemCachData.SaveToFile(System.IO.Path.Combine(Path, "DefaultData.xml"), false);
            }
