Hi All,

I developed one WCF Rest Service. get method and post methods how to call wcf rest service from web client. My code like this

----WCF Interface methods

[OperationContract]
       [WebInvoke(UriTemplate = "UpdateTrackDetails",
           Method = "POST",  RequestFormat = WebMessageFormat.Json,ResponseFormat=WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
       string UpdateTrackDetails(string trackdetails);

---WCF Implementation of Interface
public string UpdateTrackDetails(string trackdetails)
{

string time = "";
DateTime dt = new DateTime();
try
{
// System.Web.Script.Serialization.JavaScriptSerializer json = new System.Web.Script.Serialization.JavaScriptSerializer();
string result = "0";
TrackDetails _BusTrack = JsonConvert.DeserializeObject<trackdetails>(trackdetails);
time = _BusTrack.TrackTime;
string daa = Convert.ToDateTime(time).ToString("dd/MM/yyyy");
dt = Convert.ToDateTime(daa);
using (var context = new SchoolBusTrackEntities())
{
context.BusTrackDetails.Add(
new BusTrackDetail
{
BusID = Convert.ToInt32(_BusTrack.BusID),
Latitude = _BusTrack.Latitude,
Longitude = _BusTrack.Longitude,
// TrackTime = DateTime.Now
TrackTime = dt,
TrackTime1 = time
}
);
result = context.SaveChanges().ToString();
}
return "result";
}
catch (Exception ex)
{
return ex.Message;
}

}

----My Client Calling Method
public string call1()
{
string sURL = "http://localhost:52305/SchoolBusTrack.svc/UpdateTrackDetails";
BusTrack1 _test = new BusTrack1();
_test.BusID = txtBusID.Text;
_test.Latitude = txtLatitude.Text;
_test.Longitude = txtLongitude.Text;
_test.TrackTime = txtTrackTime.Text;
_test.TrackTime1 = txtTrackTime1.Text;

string JsonString = new JavaScriptSerializer().Serialize(_test);
var httpWebRequest = (HttpWebRequest)WebRequest.Create(sURL);
httpWebRequest.ContentType = "text/json";
httpWebRequest.Method = "POST";//GET
string responseText = "";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
streamWriter.Write(JsonString);//any parameter
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
responseText = streamReader.ReadToEnd();
}
return responseText;
}

---calling Differnt way in client side

string reqUrl = "http://192.168.1.46/BusWCF/SchoolBusTrack.svc/UpdateTrackDetails";

BusTrack1 _Bus = new BusTrack1();
_Bus.BusID = BusID;
_Bus.Latitude = Latitude;
_Bus.Longitude = Longitude;
_Bus.TrackTime = TrackTime;
_Bus.TrackTime1 = TrackTime1;

var JsonString = new JavaScriptSerializer().Serialize(_Bus);
// Response.Write(JsonString);
byte[] bytes = new UTF8Encoding().GetBytes(JsonString.ToString());
WebRequest request = WebRequest.Create(reqUrl);
request.Timeout = 2000;
request.Method = "POST";
request.ContentType = "application/json; charset=utf-8";
request.ContentLength = bytes.Length;
using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
{
writer.Write(JsonString);
}
WebResponse responce = request.GetResponse();
Stream reader = responce.GetResponseStream();
StreamReader sReader = new StreamReader(reader);
string outResult = sReader.ReadToEnd();
sReader.Close();

but i got the error
