The remote server returned an unexpected response: (400) Bad Request./protocolexception was unhandled.

hi,

     I created a simple web service client to consume a method from this wsdl file(http://services.healthindicators.gov/v4/SOAP.svc?wsdl): but got an error: The remote server returned an unexpected response: (400) Bad Request.  Tried all setting in app config file, but still getting the same error.

Anybody please help me sort out this problem.

Thanks in advance.

code:

using System;
using System.Xml;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using HIWTest.HiwServiceRef;

namespace HIWTest
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }


        private void button1_Click(object sender, EventArgs e)
        {

               // create soap client 
            SOAPClient soap = new SOAPClient();

                Array result = soap.GetYears(1).ToArray(); ;
                System.Xml.Serialization.XmlSerializer xs = new System.Xml.Serialization.XmlSerializer(result.GetType());
                System.IO.StreamWriter rt = new System.IO.StreamWriter("e:\\year1.xml");
                xs.Serialize(rt, result);
                rt.Close();

        }
    }
}

app.config file :
