Question

尝试调用我创建的名为pxy.AddCustomer(txtLogin.Text)的Web服务方法时出现以下错误。我在执行using System; using System.Collections.Generic; using System.Data; using System.Data.SqlClient; using System.Linq; using System.Web; using System.Web.Services; using Utilities; namespace Project4WS { /// <summary> /// Summary description for AuctionService /// </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 AuctionService : System.Web.Services.WebService { [WebMethod] public void AddCustomer(String Name) { SqlCommand objCommand = new SqlCommand(); objCommand.CommandType = CommandType.StoredProcedure; objCommand.CommandText = "AddCustomer"; objCommand.Parameters.AddWithValue("@theName", Name); DBConnect objDB = new DBConnect(); DataSet myDataSet = objDB.GetDataSetUsingCmdObj(objCommand); } } }

时强调了AddCustomer

'AuctionService'不包含'AddCustomer'的定义，并且没有扩展方法'AddCustomer'接受类型'AuctionService'的第一个参数（你是否缺少using指令或汇编引用？）

网络服务代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Project4WS;

namespace Project4
{
public partial class WebForm1 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void btnNewUser_Click(object sender, EventArgs e) 
    {
        AuctionSvcPxy.AuctionService pxy = new AuctionSvcPxy.AuctionService();

        pxy.AddCustomer(txtLogin.Text);

        Session["Customer"] = txtLogin.Text.ToString();
    }

按钮点击代码：

<!DOCTYPE html>
<html>
<head>
	<meta charset="utf-8">
	<meta name="viewport" content="width=device-width, initial-scale=1">

    </script>
  
</head>
<body>

  <script type="text/javascript">
    alert("tester");
  </script>

  <div id="main"><span id="m_timer"></span></div>
	<script type="text/javascript">
		$(function()
		{
			$("#m_timer").countdowntimer({
				minutes : 2‚
				size : "lg"
			});
		})
    </script>
  
</body>
</html>

Answer 1

Project4WS和Project4是两个不同的命名空间。因此，无法在protected void AddCustomer方法中访问btnNewUser_Click方法。为public函数设置访问修饰符AddCustomer。

Answer 2

将方法AddCustomer的访问修饰符从protected更改为public

不包含定义，也没有扩展方法错误
