（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
