I am using below code to use this web service through HttpWebRequest and
got error "The remote server returned an error: (400) Bad Request." It working fine for get method.----

C#

string postData = string.Format("user={0}&pwd={1}", "me", "123");
            HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://localhost:52631/Service1.svc/chkUserPwd");
            webRequest.Method = "POST";
            webRequest.ContentType = "application/x-www-form-urlencoded";
            webRequest.ContentLength = postData.Length;
            try
            {
                using (StreamWriter requestWriter2 = new StreamWriter(webRequest.GetRequestStream()))
                {
                    requestWriter2.Write(postData);
                }

                using (StreamReader responseReader = new StreamReader(webRequest.GetResponse().GetResponseStream()))
                {
                    // dumps the HTML from the response into a string variable
                    postData = responseReader.ReadToEnd();
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }

In can be difficult, because WCF has a number of internal machinery: service contracts, data contracts, etc. You will feel really blind-folded in parsing the messages. Why not acting as a normal WCF client?
If you say that you don't have the interfaces, I'll answer that handling generation of HTTP requests and parsing HTTP responses on the HttpWebRequest level won't make it easier...

I want url based service without using wcf client just like asmx service.

If you really want it, make it, who stops you? Perhaps wanting is not enough?

C#

credential obj = new credential();
            obj.user = "me";
            obj.pwd = "123";
            JavaScriptSerializer js = new JavaScriptSerializer();
            string postData= js.Serialize(obj);
            HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://localhost:52631/Service1.svc/chkUserPwd");
            webRequest.Method = "POST";
            webRequest.ContentType = "application/json"
            webRequest.ContentLength = postData.Length;
            try
            {
                using (StreamWriter requestWriter2 = new StreamWriter(webRequest.GetRequestStream()))
                {
                    requestWriter2.Write(postData);
                }

                using (StreamReader responseReader = new StreamReader(webRequest.GetResponse().GetResponseStream()))
                {
                    // dumps the HTML from the response into a string variable
                    postData = responseReader.ReadToEnd();
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }

C#

public class credential
        {
            public string user { get; set; }
            public string pwd { get; set; }
        }

As I mentioned on WebInvoke is BodyStyle = WebMessageBodyStyle.Wrapped then we must post the data json or xml.
