Question

我编写简单的WCF Web服务（应用程序）。 我有错误：无法添加服务。可能无法访问服务元数据。确保您的服务正在运行并公开元数据。 请帮帮我。

我的网络服务：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
using WCF;

namespace ValyutaService
{
    public class ValyutaService : IValyutaService
    {
        List<string> IValyutaService.ParaBirimleriniGetir()
        {
            List<String> paraBirimleri = new List<string>();
            paraBirimleri.Add("AZN");
            paraBirimleri.Add("USD");
            paraBirimleri.Add("EURO");
            paraBirimleri.Add("TL");
            paraBirimleri.Add("RUBL");
            return paraBirimleri;
        }

        public List<double> KurlariGetir(string kurTipi)
        {
            Random randomKur = new Random();
            ist<Double> kurlarListesi = new List<Double>();
            for (int i = 0; i < 15; i++)
            {
                kurlarListesi.Add(randomKur.NextDouble() + 2);
            }
            return kurlarListesi;
        }
    }
}

接口：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

namespace WCF
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract]
    public interface IValyutaService
    {

        [OperationContract]
        List<string> ParaBirimleriniGetir();

        [OperationContract]
        List<Double> KurlariGetir(string kurTipi);
    }



}
