问题:

(C#)调用Webservice，提示远程服务器返回错误(500)内部服务器错误

解决办法：

 Form加载时显示

        private void Form1_Load(object sender, EventArgs e)
        {
            //WeatherWebService s = new WeatherWebService();
            WindowsFormsApp1.cn.com.webxml.www.WeatherWebService w = new cn.com.webxml.www.WeatherWebService();
            string[] s = new string[23];

            s = w.getWeatherbyCityName("beijing");
            foreach (var item in s)
            {
                textBox2.Text+=item+"\r\n";
            }
        }

 Form界面显示
