WCF: The remote server returned an error: (400) Bad Request.

Question

I have created a wcf Service. The Signature of the service is as.

 

[OperationContract(Name = "CustomerBillingDetail")]

[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json,

UriTemplate = "/CustomerBillingDetail/BillDetails")]

string CustomerBillingDetail(RemoteFileInfo objRemoteFileInfo);

public class RemoteFileInfo //: IDisposable

{

//[DataMember(Order = 2)]

public int ClientId;

//[DataMember(Order = 1)]

//public System.IO.Stream FileByteStream;

public byte[] FileByte;

//public void Dispose()

//{

// if (FileByteStream != null)

// {

// FileByteStream.Close();

// FileByteStream = null;

// }

//}

}

 

I am using the method as a rest client on the UI. The UI code is as.

 

public class RemoteFileInfo //: IDisposable

{

public int ClientId;

//public System.IO.Stream FileByteStream;

public byte[] FileByte;

//public void Dispose()

//{

// if (FileByteStream != null)

// {

// FileByteStream.Close();

// FileByteStream = null;

// }

//}

}

 

 

private void GetResponseForLS()

{

try

{

string url = "http://localhost/BillingService/BillingRestService/CustomerBillingDetail/BillDetails";

string SampleXML = @"<Root xmlns=""urn:microsoft-dynamics-nav/xmlports/x50000""><Trans_Header><Store_Code>003</Store_Code><Store_Name>GREATER KAILASH</Store_Name><Name>akul</Name><Mobile>1245678900</Mobile><DoB /><Address>Lajpat Nagar New Delhi</Address><Gender /><Bill_No>3010018732</Bill_No><Coupen_Code /><Order_Type /><Bill_Date>22-03-16</Bill_Date><Bill_Amt>88.89</Bill_Amt><Email_ID>[email protected]</Email_ID><Channel_ID /><Trans_Sales_Line><Product_Name>Water Bottle 1Ltr</Product_Name><Product_ID>P259</Product_ID><Item_Amt>35.56</Item_Amt><Qty>1</Qty><Is_Combo /><Item_Type>DRY</Item_Type></Trans_Sales_Line><Trans_Sales_Line><Product_Name>FS Apple-Blueberry</Product_Name><Product_ID>PH01115</Product_ID><Item_Amt>53.33</Item_Amt><Qty>1</Qty><Is_Combo /><Item_Type>DRY</Item_Type></Trans_Sales_Line></Trans_Header></Root>";

SampleXML = RemoveAllNamespaces(SampleXML);

// declare httpwebrequet wrt url defined above

HttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create(url);

// set method as post

webrequest.Method = "POST";

// set content type

webrequest.ContentType = "application/json";

var dataContarctSerializer = new DataContractSerializer(typeof(RemoteFileInfo));

var remoteFielInfo = new RemoteFileInfo()

{

ClientId = 2,

FileByte = Encoding.UTF8.GetBytes(SampleXML)

};

using(var memoryStream = new MemoryStream())

{

using (var reader = new StreamReader(memoryStream))

{

dataContarctSerializer.WriteObject(memoryStream, remoteFielInfo);

memoryStream.Position = 0;

string body = reader.ReadToEnd();

using (var streamWriter = new StreamWriter(webrequest.GetRequestStream()))

{

streamWriter.Write(body);

}

}

}

WebResponse webresponse = webrequest.GetResponse();

Encoding enc = System.Text.Encoding.GetEncoding("utf-8");

// read response stream from response object

StreamReader loResponseStream =

new StreamReader(webresponse.GetResponseStream(), enc);

// read string from stream data

string strResult = loResponseStream.ReadToEnd();

// close the stream object

loResponseStream.Close();

// close the response object

webresponse.Close();

}

catch (Exception ex)

{

throw ex;

}

}

 

when I am trying to execute that it is showing exception on  this line

WebResponse webresponse = webrequest.GetResponse(); and the error is "The remote server returned an error: (400) Bad Request."

 

Please help me to resolve this. It is urgent.
