解决WCF的service端无法使用泛型的问题

　　思路是将其序列化（比较笨的方法……）

1、引入Newtonsoft.json.dll

2、服务端序列化：return JsonConvert.SerializeObject(result);

3、客户端反序列化：List<T> list = JsonHelper.DeserializeJsonToList<T>(resultStr);

4、封装的JsonHelper类，部分代码来自网络 ^_^

using System.Collections.Generic;
using Newtonsoft.Json;
using System.IO;
/// <summary>
/// Json帮助类
/// </summary>
public class JsonHelper
{
    /// <summary>
    /// 将对象序列化为JSON格式
    /// </summary>
    /// <param name="o">对象</param>
    /// <returns>json字符串</returns>
    public static string SerializeObject(object o)
    {
        string json = JsonConvert.SerializeObject(o);
        return json;
    }

    /// <summary>
    /// 解析JSON字符串生成对象实体
    /// </summary>
    /// <typeparam name="T">对象类型</typeparam>
    /// <param name="json">json字符串(eg.{"ID":"112","Name":"石子儿"})</param>
    /// <returns>对象实体</returns>
    public static T DeserializeJsonToObject<T>(string json) where T : class
    {
        JsonSerializer serializer = new JsonSerializer();
        StringReader sr = new StringReader(json);
        object o = serializer.Deserialize(new JsonTextReader(sr), typeof(T));
        T t = o as T;
        return t;
    }

    /// <summary>
    /// 解析JSON数组生成对象实体集合
    /// </summary>

    /// <param name="json">json数组字符串(eg.[{"ID":"112","Name":"张三"}])</param>
    /// <returns>对象实体集合</returns>
    public static List<T> DeserializeJsonToList<T>(string json) where T : class
    {
        JsonSerializer serializer = new JsonSerializer();
        StringReader sr = new StringReader(json);
        object o = serializer.Deserialize(new JsonTextReader(sr), typeof(List<T>));
        List<T> list = o as List<T>;
        return list;
    }

    /// <summary>
    /// 反序列化JSON到给定的匿名对象.

    public static T DeserializeAnonymousType<T>(string json, T anonymousTypeObject)
    {
        T t = JsonConvert.DeserializeAnonymousType(json, anonymousTypeObject);
        return t;
    }
}
