我没有得到 JSON 格式的输出。这是代码
---- IService1.cs ----
[ServiceContract]
public interface IService1
{
[OperationContract]
[WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "currency")]
List<Employee> GetAllEmployeesMethod();
[OperationContract]
string TestMethod();
[OperationContract]
[WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "players")]
List<Person> GetPlayers();
}
---- Service1.svc.cs ----
public List<Employee> GetAllEmployeesMethod()
{
List<Employee> mylist = new List<Employee>();
using (SqlConnection conn = new SqlConnection("--connection string--"))
{
conn.Open();
string cmdStr = String.Format("Select customercode,CurrencyCode,CurrencyDesc from Currency");
SqlCommand cmd = new SqlCommand(cmdStr, conn);
SqlDataReader rd = cmd.ExecuteReader();
if (rd.HasRows)
{
while (rd.Read())
mylist.Add(new Employee(rd.GetInt32(0), rd.GetString(1), rd.GetString(2)));
}
conn.Close();
}
return mylist;
}

当我运行这个服务时,我得到了数据
但我希望结果为 JSON 格式
示例: {"currencycode":"INR","DESCRIPTION":"Indian Rupees","customercode" : "1001"},....
