我的任务
分享简单Web Service出现问题
仅仅利用.net自己带的那个HelloWorld的服务，然后我添加了一个ASP.NET，
private void Button1_Click(object sender, System.EventArgs e)
{
localhost.Service1 ws1 = new localhost.Service1();
TextBox1.Text = ws1.HelloWorld();
}
就出现以下错误，怎么回事啊？
Server Error in '/HelloWorldApp' Application.

Line 36: public string HelloWorld() {
Line 37: object[] results = this.Invoke("HelloWorld", new object[0]);
Line 38: return ((string)(results[0]));
Line 39: }
private void Button1_Click(object sender, System.EventArgs e)
{
localhost.Service1 ws1 = new localhost.Service1();
TextBox1.Text = ws1.HelloWorld();
}

你没有增加引用吗？要增加引用啊，这样能用,先添加引用，然后
using 你的名字空间
HelloWorld ww=new HelloWorld();
TextBox1.Text = ws1.HelloWorld();
using 你的名字空间
HelloWorld ww=new HelloWorld();
TextBox1.Text = ws1.HelloWorld();

URL 错误，在解决方案里的LOCALHOST改URL 地址加上你的IP

你先添加WEB服务引用，在LOCALHOST属性中URL行为设为动态，在CS中添加 using 命名空间。LOCALHOST； 再添加如下代码就可以了
Service1 opj=new Service1();
this.Label1.Text=opj.HelloWorld();
Service1 opj=new Service1();
this.Label1.Text=opj.HelloWorld();

Add a web reference 以及jamzh老兄的方法都试过了，还是不行。错误是连不上远端服务器，会是什么原因呢？

你的WebServices 的URL地址错误。或你连接WebServices所在的服务器连接不上
你可以在代码中加一段
private void Button1_Click(object sender, System.EventArgs e)
{
localhost.Service1 ws1 = new localhost.Service1();
ws1.url="http://Servername/xxx/WebSerives.asmx"
TextBox1.Text = ws1.HelloWorld();
}
