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
实现方式:ServiceReference1.Service1SoapClient ser1 = new ServiceReference1.Service1SoapClient("Service1SoapClient");
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); }
3-System.Net.WebRequest
实现方式:System.Net.WebRequest webObj = System.Net.WebRequest.Create("http://xx.xx.xx.xxx:xxxx/InterfaceService.asmx/DownLoadSO?sono=" + tbox_so.Text.Trim() + "");
protected void btn_SoSubmit_Click(object sender, EventArgs e) { string strResult = ""; try { if (string.IsNullOrEmpty(tbox_so.Text.Trim())) { strResult = "{\"Result\":\"FAIL\",\"Data\":\"FAIL,请输入销售单!\"}"; return; } System.Net.WebRequest webObj = System.Net.WebRequest.Create("http://xx.xx.xx.xxx:xxxx/InterfaceService.asmx/DownLoadSO?sono="
+ tbox_so.Text.Trim() + ""); StreamReader streamOjb = new StreamReader(webObj.GetResponse().GetResponseStream(), System.Text.Encoding.Default); strResult = streamOjb.ReadLine(); streamOjb.Close(); } catch (Exception ex) { strResult = "{\"Result\":\"FAIL\",\"Data\":\"FAIL," + ex.Message + "\"}"; } finally { if (strResult.Contains("{\"Result\":\"FAIL\"")) { lbl_msg_so.ForeColor = System.Drawing.Color.Red; } else { lbl_msg_so.ForeColor = System.Drawing.Color.Green; } strResult = strResult.Substring(strResult.IndexOf("Data") + 7); lbl_msg_so.Font.Size = FontUnit.Larger; lbl_msg_so.Text = strResult.Substring(0, strResult.Length - 2); } }
4-HTTP POST 调用WebMethod
var url = "http://localhost:51013/Service1.asmx/GetData"; var values = new System.Collections.Specialized.NameValueCollection(); values.Add("data", "hi server"); var client = new WebClient(); var data = client.UploadValues(url, "POST", values); var result = System.Text.Encoding.UTF8.GetString(data); Console.WriteLine(result); // 输出: // <?xml version="1.0" encoding="utf-8"?> // <string xmlns="http://tempuri.org/">You enter:hi server</string>
5-HTTP GET调用WebMethod
var url3 = "http://localhost:51013/Service1.asmx/GetData3?data=‘test‘"; var client3 = new WebClient(); client3.Headers.Add("Content-Type", "application/json"); var result3 = client3.DownloadString(url3); Console.WriteLine(result3);
//输出: //You enter:test
注意:GET调用时是通过Url传值,如果是string需要使用 data=‘test‘ 两边加上单引号,因为使用json反序列化。没有引号直接当成是数值转换会出错。(将抛出 500 的服务端错误)
