                Name:            
                     
                Title:            
                     
                Department:            
                
                
                     
                            
                
           
      
    
     
            
            Employee:
        
      
    

后台代码如下：

[WebMethod]        public void EmployeeList()        {            string action = Context.Request.QueryString["a"];            if (action.Equals("add"))            {                addEmployee(Context.Request, Context.Response);            }            else if (action.Equals("delete"))            {                deleteEmployee(Context.Request, Context.Response);            }        }        private void deleteEmployee(HttpRequest httpRequest, HttpResponse httpResponse)        {            string id = httpRequest.QueryString["id"];            StringBuilder xml = new StringBuilder("
     
      ");            xml.Append("
      
       1
      ");            xml.Append("
     ");            sendResponse(httpResponse, xml.ToString());        }        private void addEmployee(HttpRequest httpRequest, HttpResponse httpResponse)        {            string uniqueID = storeEmployee();            StringBuilder xml = new StringBuilder("
     
      
       ");            xml.Append(uniqueID);            xml.Append("
      ");            xml.Append("
      
       1
      ");//书中没有这行代码，请注意            xml.Append("
     ");            sendResponse(httpResponse, xml.ToString());        }        private void addEmployee()        {        }        private void sendResponse(HttpResponse httpResponse, string responseText)        {            httpResponse.ContentType = "text/xml";            httpResponse.Write(responseText);        }        private string storeEmployee()        {            string uniqueID = "";            Random r = new Random();            for (int i = 0; i < 8; i++)            {                uniqueID += r.Next(9);            }            return uniqueID;        }
