简单的WindowsForm Client与WebService通信例子[对象的序列化与反序列化]

1.创建一个WebService,添加一个自定义类:

using System;
using System.Web.Services;
using System.Xml;
using System.Xml.Serialization;
using System.Xml.Schema;
using System.Collections;


namespace WebServiceForStock
{
    public class Person
{
        [XmlElement(ElementName="UserName")]
        public string Name;
        [XmlElement(ElementName="UserAge")]
        public int Age;
    }
    public class User
{
        public Person personInstance ;
        [XmlElement(ElementName="UserEmail")]
        public string Email;
        [XmlElement(ElementName="UserPassword")]
        public string pwd;

    }


    /// CustomizeClass 的摘要说明。
    /// 自定义类用XML序列化
    /// 可以返回复合的类
    /// </summary>
    public class CustomizeClass
{

        [XmlAttribute()]public int orderID;
        public DateTime orderTime;
        [XmlElement("DateTimeRequired")]public DateTime requiredDate;
        public DateTime shippedDate;
        public ArrayList Details;
        [XmlIgnore]public string SalesPersonID;
        public CustomizeClass()
{
            //
            // TODO: 在此处添加构造函数逻辑
            //
        }        
    }
    
    [XmlRoot(Namespace = "http://www.cnblogs.com/slashout/")]
    public class Group
{
        public string GroupName;

        // This is for serializing Employee elements.
        [XmlAnyElement(Name = "Employee")]
        public XmlElement[] UnknownEmployees;

        // This is for serializing City elements.   
        [XmlAnyElement
             (Name = "City", 
             Namespace = "http://www.cnblogs.com/slashout/")]
        public XmlElement[] UnknownCity;

        // This one is for all other unknown elements.
        [XmlAnyElement]
        public XmlElement[] UnknownElements;
    }


}

2.在Service.asmx内进行编辑

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Web;
using System.Web.Services;

namespace WebServiceForStock
{

    /// Service1 的摘要说明。
    /// </summary>
    public class Service1 : System.Web.Services.WebService
{
        public Service1()
{
            //CODEGEN: 该调用是 ASP.NET Web 服务设计器所必需的
            InitializeComponent();
        }

        private System.Windows.Forms.TextBox textBox1;

    


        
        //Web 服务设计器所必需的
        private IContainer components = null;
                

        /// 设计器支持所需的方法 - 不要使用代码编辑器修改
        /// 此方法的内容。
        /// </summary>
        private void InitializeComponent()
{
            this.textBox1 = new System.Windows.Forms.TextBox();
            // 
            // textBox1
            // 
            this.textBox1.Location = new System.Drawing.Point(17, 17);
            this.textBox1.Name = "textBox1";
            this.textBox1.TabIndex = 0;
            this.textBox1.Text = "textBox1";

        }


        /// 清理所有正在使用的资源。
        /// </summary>
        protected override void Dispose( bool disposing )
{
            if(disposing && components != null)
{
                components.Dispose();
            }
            base.Dispose(disposing);        
        }
        
        #endregion

        // WEB 服务示例
        // HelloWorld() 示例服务返回字符串 Hello World
        // 若要生成，请取消注释下列行，然后保存并生成项目
        // 若要测试此 Web 服务，请按 F5 键

        [WebMethod]
        public User StockService(int UserID)
{
            User newUser=new User();
            newUser.personInstance=new Person();
            newUser.personInstance.Name="Slashout";
            newUser.personInstance.Age=25;
            newUser.Email="slashout@163.com";
            newUser.pwd="test";
            return newUser;
        }
    }
}

3.添加一个WindowsApp工程,添加Web引用,本人用的引用名称为 EDIService

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.Web;
using ServiceClient.EDIService;

namespace ServiceClient
{

    /// Form1 的摘要说明。
    /// </summary>
    public class Form1 : System.Windows.Forms.Form
{
        private System.Windows.Forms.Button button1;
        private System.Windows.Forms.Button button2;
        private System.Windows.Forms.TextBox textName;
        private System.Windows.Forms.TextBox textAge;
        private System.Windows.Forms.TextBox textEmail;
        private System.Windows.Forms.TextBox textPassword;

        /// 必需的设计器变量。
        /// </summary>
        private System.ComponentModel.Container components = null;

        public Form1()
{
            //
            // Windows 窗体设计器支持所必需的
            //
            InitializeComponent();

            //
            // TODO: 在 InitializeComponent 调用后添加任何构造函数代码
            //
        }


        /// 清理所有正在使用的资源。
        /// </summary>
        protected override void Dispose( bool disposing )
{
            if( disposing )
{
                if (components != null) 
{
                    components.Dispose();
                }
            }
            base.Dispose( disposing );
        }



        /// 设计器支持所需的方法 - 不要使用代码编辑器修改
        /// 此方法的内容。
        /// </summary>
        private void InitializeComponent()
{
            this.button1 = new System.Windows.Forms.Button();
            this.button2 = new System.Windows.Forms.Button();
            this.textName = new System.Windows.Forms.TextBox();

            this.button1.Click += new System.EventHandler(this.button1_Click);

            this.textAge.Text = "Age";
            // 
            // textEmail
            // 
            this.textEmail.Location = new System.Drawing.Point(64, 96);
            this.textEmail.Name = "textEmail";
            this.textEmail.Size = new System.Drawing.Size(208, 21);
            this.textEmail.TabIndex = 4;

            this.Controls.Add(this.textPassword);
            this.Controls.Add(this.textEmail);

            this.Name = "Form1";
            this.Text = "Form1";
            this.ResumeLayout(false);

        }
        #endregion


        /// 应用程序的主入口点。

        [STAThread]
        static void Main()

            Application.Run(new Form1());

        private void button2_Click(object sender, System.EventArgs e)

4.好了,那么我们将WindowsApp设为启动项目,可以运行了^^

5.WebService返回的SOAP消息是这样的:

  <?xml version="1.0" encoding="utf-8" ?> 
- <User xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://tempuri.org/">
- <personInstance>
  <UserName>Slashout</UserName> 
  <UserAge>25</UserAge> 
  </personInstance>
  <UserEmail>slashout@163.com</UserEmail> 
  <UserPassword>test</UserPassword> 
  </User>

5.这个小代码段非常简单,但是你可以在WebService部分扩展自定义的类,从Web DB上返回你需要串行化的对象实例,其实BizLogic的复杂度参看具体项目.但是底层实现基本都差不多的^^.

总之很简单就很容易看懂了^^.
