WebService简单示例

建一个webService:

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;

namespace WebApplication1
{
    /// <summary>
    /// WebService1 的摘要说明
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。
    // [System.Web.Script.Services.ScriptService]
    public class WebService1 : System.Web.Services.WebService
    {
        public Createntials toKen;

        [WebMethod(Description = "获取全部公告")]
        [SoapHeader("toKen", Direction = SoapHeaderDirection.In)] 
        public List<Person> GetPersonList()
        {
            if (toKen.AccountID != "admin" || toKen.PIN != "admin")
            {
                return null;
            }

            return new PersonData().GetDataSource();
        }
    }

    /// <summary>
    /// 用于WebService的安全性
    /// </summary>
    public class Createntials : System.Web.Services.Protocols.SoapHeader
    {
        public string AccountID;
        public string PIN;
    }

    public class PersonData
    {
      public List<Person> personList = new List<Person>() 
        { 
             new Person(){Id=1,Name="张三",Address="浙江金华"},
             new Person(){Id=2,Name="李四",Address="浙江杭州"},
             new Person(){Id=3,Name="赵六",Address="浙江温州"}
        };

        public List<Person> GetDataSource()
        {
            return personList;
        }

        public Person GetPersonByID(int id)
        {
            return personList.FirstOrDefault(p => p.Id == id);
        }

        public List<Person> GetPersonByName(string name)
        {
            return personList.Where(p => p.Name == name).ToList();
        }
    }


    public class Person
    {
        private int id;

        public int Id
        {
            get { return id; }
            set { id = value; }
        }

        private string name;

        public string Name
        {
            get { return name; }
            set { name = value; }
        }

        private string address;

        public string Address
        {
            get { return address; }
            set { address = value; }
        }
    }
}

 

 

调用WebService代码:

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace WebApplication2
{
    public partial class _Default : System.Web.UI.Page
    {
        
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                //创建调用的WebService类的对象
                localhost.WebService1 ws = new localhost.WebService1();

                //验证
                ws.CreatentialsValue = new localhost.Createntials() { AccountID = "admin", PIN = "admin" };

                //返回的集合会转成数组
                localhost.Person[] pArray = ws.GetPersonList();

                GridView1.DataSource = pArray;
                GridView1.DataBind();

                //也可以将数组转成集合
                //List<localhost.Person> list = new List<localhost.Person>();

                //foreach (localhost.Person item in pArray)
                //{
                //    list.Add(item);
                //}

                //GridView1.DataSource = list;
                //GridView1.DataBind();
            }
        }
    }
}
