如何在客户端 ASP.NET MVC 3/4 中使用 WCF RESTfull 服务？我已经实现了带有列表的返回类型的示例 RESTfull 服务 

[ServiceContract]
public interface IService1
{
    [OperationContract]
    [WebGet(UriTemplate = "/mycities", ResponseFormat = WebMessageFormat.Json)]
    List<string> GetData();

    [OperationContract]
    [WebGet(UriTemplate = "/mycities1/{cityId}",ResponseFormat =WebMessageFormat.Json)]
    string GetData1(string cityId);

    [OperationContract]
    [WebGet(UriTemplate = "/XMLCity", ResponseFormat = WebMessageFormat.Xml)]
    List<string> GetDataXML();

    [OperationContract]
    [WebGet(UriTemplate = "/EmployeesXML", ResponseFormat = WebMessageFormat.Xml)]
    List<Employee> GetEmployeeXML();
}



        public List<string> GetData()
        {

            List<string> cities = new List<string>();
            cities.Add("Ahamadabad");
            cities.Add("Chennai");
            cities.Add("Bengaluru");
            cities.Add("Delhi");
            cities.Add("Kolkata");
            cities.Add("Mumbai");

            return cities;

        }

    public string GetData1(string cityId)
    {

        List<string> cities = new List<string>();
        cities.Add("Ahamadabad");
        cities.Add("Chennai");
        cities.Add("Bengaluru");
        cities.Add("Delhi");
        cities.Add("Kolkata");
        cities.Add("Mumbai");

        ShoppingCartAPIEF.ShoppingCartAdminEntities db = new ShoppingCartAPIEF.ShoppingCartAdminEntities();
        var customer = db.Customers.ToList();

        var id =  Convert.ToInt16( cityId);
        var cust = from c in customer
                   where c.Id == Convert.ToInt16(cityId)
                   select c;

        return cust.Select(l => new { l.LastName }).FirstOrDefault().LastName;
    }

    public List<string> GetDataXML()
    {

        List<string> cities = new List<string>();
        cities.Add("Ahamadabad");
        cities.Add("Chennai");
        cities.Add("Bengaluru");
        cities.Add("Delhi");
        cities.Add("Kolkata");
        cities.Add("Mumbai");

        return cities;

    }

        public List<Employee> GetEmployeeXML()
        {
            List<Employee> employees = new List<Employee>();


            Employee emp = new Employee { EmpId = 100, FirstName = "JaiSankar", LastName = "Navarathinam" };
             Employee emp1 = new Employee { EmpId = 101, FirstName = "Vimmal", LastName = "Lodaya" };
            Employee emp2 = new Employee { EmpId = 102, FirstName = "Ganapathy", LastName = "Thayanidhi" };
            //new Employee { EmpId = 103, FirstName = "Sivakumar", LastName = "LaxmanaPerumal" };
            //new Employee { EmpId = 104, FirstName = "Gajendra", LastName = "Gowda" };

            employees.Add(emp);
            employees.Add(emp1);
            employees.Add(emp2);

            return employees;
        }

客户端应用程序：控制台：

方法一：我们消费WCF应用时，在客户端添加服务引用，调用如下。这就像普通的 WCF 应用程序

    ServiceReference1.Service1Client client1 = new ServiceReference1.Service1Client();
    var name = client1.GetData1("2");
    //Output: single name

    var cityNames = client1.GetData();
    //Output: List of strings

    var employees = client1.GetEmployeeXML();
    //OutPut: List of Employees

方法2：如果是普通的WCF应用，上述方法就可以了，所以我尝试如下使用WCF RESTfull服务

        using (HttpClient client = new HttpClient())
    {
        client.BaseAddress = new Uri("http://localhost:57278");

        //JSON with list of strings
        HttpResponseMessage response = client.GetAsync("Service1.svc/XMLService/mycities").Result;
        string json = response.Content.ReadAsStringAsync().Result;
        //OutPut:  ["Ahamadabad","Chennai","Bengaluru","Delhi","Kolkata","Mumbai"]

        //XML with List of strings
        HttpResponseMessage responseXML = client.GetAsync("Service1.svc/XMLService/XMLCity").Result;
        var xml = responseXML.Content.ReadAsStringAsync().Result;
        //XmlDocument doc = new XmlDocument();
        //doc.LoadXml(xml);

//输出：AhamadabadChennaiBengaluru德里加尔各答孟买

        //XML with Employee object
        HttpResponseMessage responseXML1 = client.GetAsync("Service1.svc/XMLService/EmployeesXML").Result;
        var xml1 = responseXML1.Content.ReadAsStreamAsync().Result;

//返回 ((System.IO.MemoryStream)(xml1)) }

在这里，我只有 JSON 字符串列表或 ArrayOfstring Xml 标记即将到来。如何在客户端将 JSON 转换为字符串列表或 Employee 对象。

我的问题是如何从字符串列表或 AraryOfString 或 MemoryStream 进行进一步操作。

提前感谢杰。
