Wp7 调用WebService

Wp7可以方便得调用.net的WebService

 

先用C#做一个WebService，实现两个接口

GetMessage ：发一条信息

SendMessage ：接受最新一条信息

using System; using System.Data; using System.Web; using System.Collections; using System.Web.Services; using System.Web.Services.Protocols; using System.ComponentModel; using System.Data.SqlClient; using COM; namespace WindowsService { /// <summary> /// Service1 の概要の説明です /// </summary> [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ToolboxItem(false)] public class Service1 : System.Web.Services.WebService { [WebMethod] public Message GetMessage(String id) { SqlConnection SqlCon = new SqlConnection(); DataSet ds = new DataSet(); Message msg = null; try { SqlCon = DBUtil.getSqlConnection(); DBUtil.SelectSqlCommand(ds, "select TOP 1 body,sms_time from SMSTbl where id = '" + id + "' order by sms_time DESC", ref SqlCon); if (ds.Tables[0].Rows.Count > 0) { msg = new Message(); msg.body = ds.Tables[0].Rows[0][0].ToString(); msg.time = ds.Tables[0].Rows[0][1].ToString(); } return msg; } finally { DBUtil.closeConnection(SqlCon); } } [WebMethod] public int SendMessage(String id, String body) { SqlConnection SqlCon = new SqlConnection(); try { SqlCon = DBUtil.getSqlConnection(); return DBUtil.InsertSqlCommand("Insert into SMSTbl( id,sms_time,body) values('" + id + "',getdate(),'" + body + "')", ref SqlCon); } finally { DBUtil.closeConnection(SqlCon); } } } }

 

再在wp7 程序引用WebService

 

 

在wp7里调用它

 

//添加引用 using DecoMailer.ServiceReference1; //在[按钮]押下事件中 private void KanjiModeButton_Click(object sender, RoutedEventArgs e) { //实例化SoapClient ServiceReference1.Service1SoapClient soap = new Service1SoapClient(); //调用GetMessage方法，并把ID:1传给方法 soap.GetMessageAsync("1"); //Respones将触发GetMessageCompletedEvent事件，并调用soap_GetMessage处理 soap.GetMessageCompleted += new EventHandler<GetMessageCompletedEventArgs>(soap_GetMessage); } private void soap_GetMessage(object sender, GetMessageCompletedEventArgs e) { if (e.Error == null) { //取得最新的Message类对象 ServiceReference1.Message lastMessage = e.Result; //MessageEditor.Message = lastMessage; } }
