（一）创建Web Service

创建第一个项目，类型选择asp.net Empty Web application

添加一个新项目 Web Service

然后再创建一个类Contact

代码分别如下。

Contact.cs:

    [Serializable]    public class Contact    {        PRivate string name;        public string Name        {            get { return name; }            set { name = value; }        }        private int age;        public int Age        {            get { return age; }            set { age = value; }        }    }

HelloWebService.asmx.cs:

    /// <summary>    /// Summary description for HelloWebService    /// </summary>    [WebService(Namespace = "http://tempuri.org/")]    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]    [System.ComponentModel.ToolboxItem(false)]    // To allow this Web Service to be called from script, using ASP.NET Ajax, uncomment the following line.     // [System.Web.Script.Services.ScriptService]    public class HelloWebService : System.Web.Services.WebService    {        [WebMethod]        public string GetMessage(string name)        {            return "Hello " + name;        }        [WebMethod]        public Guid CreateContact(Contact c)        {            return Guid.NewGuid();        }    }

（二）创建客户端

下面创建一个客户端调用Web Service，检验一下是否正确。创建一个ASP.NET Empty Web Application

添加服务引用

WebForm1.cs代码为

        protected void Button1_Click(object sender, EventArgs e)        {            HelloWebService.HelloWebServiceSoapClient client = new HelloWebService.HelloWebServiceSoapClient();            Label1.Text = client.GetMessage(TextBox1.Text);        }        protected void Button2_Click(object sender, EventArgs e)        {            HelloWebService.HelloWebServiceSoapClient client = new HelloWebService.HelloWebServiceSoapClient();            Label2.Text = client.CreateContact(new HelloWebService.Contact()).ToString();        }

最后运行客户端，分别点击按钮，得到演示效果
