C#调用Webservice的几种方式

1-添加服务引用；

　　（1）工程 - Service References - 添加服务引用；

　　（2）在“添加服务引用”中输入Webservice网站发布地址，并敲回车或点击“转到”；

　　（3）调用代码编写

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using WebServiceTestApp.ServiceReference1;//添加引用

namespace WebServiceTestApp
{
    public partial class Form1 : Form
    {
        ServiceReference1.Service1SoapClient myWebService = null;//设置变量
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            myWebService = new ServiceReference1.Service1SoapClient("Service1Soap");//实例化变量
        }

        private void btnUpLoadCycleTime_Click(object sender, EventArgs e)
        {
            //test
            string SerialNumber = "160719070002873";
            string StationName = "3120";
            string MachineName = @"http://xx.xx.xx.xxx:8001/Service.asmx?";
            string Employee = "user";
            string Password = "123";
            float CycleTime = 0;
            bool Result = false;
            DataTable ChildSNList = null;
            string Message = String.Empty;
            //调用Webservice方法如下
            ServiceReference1.Service1SoapClient ser1 = new ServiceReference1.Service1SoapClient("Service1SoapClient");
            myWebService.UpLoadCycleTime(SerialNumber, StationName, MachineName,
                Employee, Password, CycleTime,
                out Message);
        }
}
}

2-添加Web引用

　　（1）工程添加Webservice方法如下　　

　　（2）C#调用Webservice代码实现　　

private void btnStationManage_Click(object sender, EventArgs e)
        {
            //test
            WebReference.Service1 webservice = new WebReference.Service1();
            
            //测试接口过站Json如下：
            string strJson = "[{\"serialnumber\":\"999919250000001\"}]";
            DataTable Output_table = null;
            string result = String.Empty;
            Output_table = webservice.Station_Manage(strJson, out result);

            //测试前进站检查Json如下：
            string strJson2 = "[{\"serialnumber\":\"999919250000001\"}]";
            DataTable Output_table2 = null;
            string result2 = String.Empty;
            Output_table2 = webservice.Station_Manage(strJson2, out result2);

        }
