从配置文件实现WCF的调用

   使用配置文件

1.创建一个类库

添加”System.ServiceModel“引用

IHelloService:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Data;

using System.ServiceModel;

namespace wcfService

{

    [ServiceContract]

public     interface IHelloService

    {

        [OperationContract]

        DateTime GetDataTime();

          [OperationContract]

        DataTable GetUserInfo();

    }

}

View Code

2.创建一个windows窗体程序

添加”System.ServiceModel“,还有项目wcfservice层的引用

HelloService:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Data;

using System.Data.SqlClient;

using wcfService;

namespace WinformHello

{

public    class HelloService:IHelloService

    {



        public DateTime GetDataTime()

        {

            return DateTime.Now;

        }



        public System.Data.DataTable GetUserInfo()

        {

            string sql = @"Data Source=.;Initial Catalog=Students;User ID=sa;Password=abcd1234!";

            SqlConnection conn = new SqlConnection();

            SqlDataAdapter sda = new SqlDataAdapter("select  * from student",conn);

            //DataSet ds = new DataSet();

            DataTable dt = new DataTable();

            sda.Fill(dt);

            return dt;

        }

    }

}

            host.Open();

            label1.Text = "服务已启动……";
