Codigo fuente acuse de recibo

Question

Cordial Saludo,

Estoy desarrollando en lenguaje c# el consumo del web services para acuse de recibo en la DIAN resolucion 085

Necesito ayuda de como debo enviar el parametro contenfile al metodo SendEventUpdateStatus del Web Services WcfDianCustomerServicesClient

La comunicacion con el web services esta bien porque si me funcionó el metodo GetStatus

El Error que me vota la DIAN es:

MIMEType del archivo inválido (text/xml)

debes generar un zip y darle como entrada el xml del evento y pasarlo como byte() para el parametro del servicio: client.SendEventUpdateStatus(bytesZip)
