Service Encountered an error

Hi Marcus thanks for your reply.

My interface part is

[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "{DataBaseName}/{TableName}/UploadImages?ID={ID}")]
bool UploadImage(string DataBaseName, string TableName, int ID, Stream ImageStream);



My Implement part is




public bool UploadImage(string ServiceName, string TableName, int ID, Stream ImageStream)


{
try

{

byte[] Picture= InsertImage(ImageStream);


my connectionstring and mysql command here(insert Upload image to the DB)
.....
}





public static byte[] GetImage(Stream ImageStream)

{
BinaryReader reader = new BinaryReader(ImageStream);

byte[] photo = reader.ReadBytes((int)ImageStream.Length);


reader.Close();

ImageStream.Close();


return photo;

}
