急阿！如何调用WebService

添加web引用
或者用ajax调用

点出来了的，说是无法加载协定为“ServiceReference.Service1Soap”的终结点配置
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms; namespace Wclient
{
    public partial class Form1 : Form
    {
        private ServiceReference.Service1SoapClient Client;
        public Form1()
        {
            InitializeComponent();
        }        private void Form1_Load(object sender, EventArgs e)
        {        }        private void button1_Click(object sender, EventArgs e)
        {
            Client = new ServiceReference.Service1SoapClient();
             string name = Client.showtime();
　　          textBox1.Text=name;
        }
    }
}

首先在在bin文件夹下面添加服务，在到类里面引入命名空间。
接着就实例化webservice，实例名。具体的方法....完毕..........

我引用后.默认命名空间为localhost
调用代码如下:   private void button1_Click(object sender, EventArgs e)
        {
            new localhost.Service1().HelloWorld();
        }

WCF呀.
你的客户端加App.config了吗?

既然已经添加了引用,那就可以像用本地的DLL那样用啦.
Web引用名.命名空间.类名 cc=new Web引用名.命名空间.类名(参数)
cc.方法(参数)

我的ServiceReference里有好多个类的HelloWorldRequest,HelloWorldRequest1,HelloWorldResponse,HelloWorldResponse1,Service1HttpGetClient..

一般可以点出来就没有什么问题的
看下你写的webservice共享没有（每个方法前面加上 [*******]）具体的什么忘记了

<client>
      <endpoint address="http://localhost/WcfWebService/WcfServiceLibrary/Service1/"
        binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IService11"
        contract="ServiceReference1.IService1" name="WSHttpBinding_IService11">
        <identity>
          <dns value="localhost" />
        </identity>
      </endpoint>
    </client>看你的App.Config中这个Client结点下..有几个endpoint.
看你的提示..不只一个..

能贴出来客户端调用的App.Config吗?

就是运行后显示：无法加载协定为“ServiceReference.Service1Soap”的终结点配置,因为找到了协定的多个终结点配置.请按名称指示首选的终结点配置

                name="Service1Soap12" />
        </client>
这两个<endpoint>都有用吗?
是引用的时候自动生成的吗?你可以先把里面的内容清空..再重新引用一下..看行不

<client>
            <endpoint address="http://localhost:8000/Service1.asmx" binding="basicHttpBinding"
                bindingConfiguration="Service1Soap" contract="ServiceReference.Service1Soap"
                name="Service1Soap" />
            <endpoint address="http://localhost:8000/Service1.asmx" binding="customBinding"
                bindingConfiguration="Service1Soap12" contract="ServiceReference.Service1Soap"
                name="Service1Soap12" />
        </client>
把上面的endpoint删除..只留下面那个..应该有一个是不正确的..
不行.就把下面的删除..留上面的..

嗯..没关系..你试试..自动生成的有时也会因为某些原因有问题..
试试下面的方法
<client>
            <endpoint address="http://localhost:8000/Service1.asmx" binding="basicHttpBinding"
                bindingConfiguration="Service1Soap" contract="ServiceReference.Service1Soap"
                name="Service1Soap" />
            <endpoint address="http://localhost:8000/Service1.asmx" binding="customBinding"
                bindingConfiguration="Service1Soap12" contract="ServiceReference.Service1Soap"
                name="Service1Soap12" />
        </client>
把上面的endpoint删除..只留下面那个..应该有一个是不正确的..
不行.就把下面的删除..留上面的..

可能是你的WCF本身有点问题吧..可能是你改动过什么东西..
不过没事..删除没用的就行.

楼上的再问下看HelloWorldRequest和HelloWorldRequest1是啥意思啊?

我记得我碰到过这事..是因为引用了两次WebService..
如果是你删除原来的再引用就没事..

呵..那是引用WEbService生成的代理类里面的东西..不用管他们..
