public:
void SetResult(
byte id,
DicomAssociateAcceptResultType result
)
id
Presentation Context ID of the Presentation Context whose result is to be set. The ID provides information about both the class type of the data and the Transfer Syntax to use when transferring the data. It also identifies a specific Presentation Context within an Associate.
result
Result to set.
This method is only valid for DICOM Associates of type Associate Accept.
This is a comprehensive sample that shows how to use DICOM associates both on the SCP (server) and the SCU (client) sides.
