I am developing web application using WCF Service,i have created service and consumed that service in client application,i am uploading one text file for
matching the fileds after uploading the txt file,i am getting following error at client page
There was an error while trying to serialize parameter http://tempuri.org/:lblHide. The InnerException message was 'Type 'ASP.WCFApp_aspx' with data contract name 'WCFApp_aspx:http://schemas.datacontract.org/2004/07/ASP' is not expected. Consider using a DataContractResolver or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer.'. Please see InnerException for more details. ---> System.Runtime.Serialization.SerializationException: Type 'ASP.WCFApp_aspx' with data contract name 'WCFApp_aspx://schemas.datacontract.org/2004/07/ASP' is not expected. Consider using a DataContractResolver or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer.
Please see the code below, WCFService.cs:
[OperationContract]
[ServiceKnownType(typeof(string))]
[ServiceKnownType(typeof(List<string>[]))]
string KeyFieldsMatch(List<string>[] lst, Label lblHide, string strConn);
IWCFService.svc.cs:
public class WCFService: IWCFService
{
public string KeyFieldsMatch(List<string>[] lst, Label lblHide, string strConn)
{
try
{
return objBAL.KeyFieldsMatch(lst, lblHide, strConn);
}
catch
{
throw new FaultException("Error....");
}
}
}
Client:
WCFService.WCFServiceClient objBAL = new WCFService.WCFServiceClient();
protected void btnSubmit_Click(object sender, EventArgs e)
{
List<string>[] list = new List<string>[2]
string[][] lst = new string[2][];
lst = list.Select(a => a.ToArray()).ToArray();
string KeyFieldsMatch =string.empty;
KeyFieldsMatch = objBAL.KeyFieldsMatch(lst, lblHide, strConn);--Error coming at this location.
}
i am using basicHttpBinding
Any help would be appreciated.
