通過添加服務引用後生成的代碼，可以得知首先要設置Basic連接寫法的屬性，並且設置WCF服務的地址：

我在這裏建立工廠類如下：

using System;
using System.ServiceModel;
using System.ServiceModel.Channels;
using ShoppingMall.Enums;

namespace ShoppingMall.ClientBll
{
    public class EndpointFactory
    {
        private static Binding GetBindingForEndpoint(EndpointConfigurationEnums endpointConfiguration)
        {
            
 
if ((endpointConfiguration == EndpointConfigurationEnums.BasicHttpBinding_ICustomerService))
            {
                BasicHttpBinding result = new BasicHttpBinding();
                result.MaxBufferSize = int.MaxValue;
                result.ReaderQuotas = System.Xml.XmlDictionaryReaderQuotas.Max;
                result.MaxReceivedMessageSize 
 
= int.MaxValue;
                result.AllowCookies = true;
                return result;
            }
            throw new InvalidOperationException(string.Format("找不到名稱為“{0}”的終結點。", endpointConfiguration));
        }

        private static EndpointAddress GetEndpointAddress(EndpointConfigurationEnums endpointConfiguration)
        {
            
 
if ((endpointConfiguration == EndpointConfigurationEnums.BasicHttpBinding_ICustomerService))
            {
                return new EndpointAddress("http://你的地址");
            }
            throw new InvalidOperationException(string.Format("找不到名稱為“{0}”的終結點。", endpointConfiguration));
        }

        public static Binding GetDefaultBinding()
        {
            return GetBindingForEndpoint(EndpointConfigurationEnums.BasicHttpBinding_ICustomerService);
        }

        public static EndpointAddress GetDefaultEndpointAddress()
        {
            return GetEndpointAddress(EndpointConfigurationEnums.BasicHttpBinding_ICustomerService);
        }
    }

}

然後，在客戶端調用時需要調用類繼承ClientBase類並且繼承WCF的接口，該類的類型是服WCF接口的類型

並且要再客戶端調用類的構造參數中繼承ClientBase的構造方法，實例化Basic以及WCF服務的地址

最後通過繼承ClientBase的Channel方式調用服務方法，完全代碼如下：

using Microsoft.Extensions.Configuration;
using ShoppingMall.IService;
using ShoppingMall.Model;
using System.Collections.Generic;
using System.ServiceModel;

namespace ShoppingMall.ClientBll
{
    public class CustomerBll:ClientBase<ICustomerService>, ICustomerService
    {
        public IConfigurationRoot configuration; 
        public CustomerBll() : base(EndpointFactory.GetDefaultBinding(), EndpointFactory.GetDefaultEndpointAddress())
        {

        }

        public List<Buyer> GetBuyerList()
        {
            return Channel.GetBuyerList();
        }

        public bool InsertBuyerInfo(Buyer info)
        {
            return Channel.InsertBuyerInfo(info);
        }

    }
}

其次，WCF的服務接口應該有對應標記，例如：

using ShoppingMall.Model;
using System.Collections.Generic;
using System.ServiceModel;

namespace ShoppingMall.IService
{
    /// <summary>
    /// 用戶信息處理服務
    /// </summary>
    [ServiceContract]
    public interface ICustomerService
    {
        /// <summary>
        /// 獲取買家列表
        /// </summary>
        /// <returns></returns>
        [OperationContract]
        List<Buyer> GetBuyerList();

        /// <summary>
        /// 添加買家信息
        /// </summary>
        /// <returns></returns>
        [OperationContract]
        bool InsertBuyerInfo(Buyer info);
    }


}

這樣，接口標記：

ServiceContract。
方法標記：

OperationContract
