SendNSetRequest Method (DicomNet)

Show in webframe
Example 







Leadtools.Dicom Namespace > DicomNet Class : SendNSetRequest Method
The Presentation Context ID. The ID provides information about both the class type of the data and the Transfer Syntax to use when transferring the data.
The Message ID. Each message sent by a member of a connection should have a unique ID. Since a member of a connection may send several messages, this ID allows that member to identify when a specific request has been completed.
The class affected by the request. This will be a SOP Class or a Meta SOP Class.
The instance of the class. A server may, for example, have three instances of the Nuclear Medicine Class. This value identifies the data with a specific instance.
A DicomDataSet object that contains the Data Set which contains the new information to set.
Sends an N-GET-RSP message to a peer member of a connection.

Parameters
presentationID


The Presentation Context ID. The ID provides information about both the class type of the data and the Transfer Syntax to use when transferring the data.
messageID


The Message ID. Each message sent by a member of a connection should have a unique ID. Since a member of a connection may send several messages, this ID allows that member to identify when a specific request has been completed.
affectedClass


The class affected by the request. This will be a SOP Class or a Meta SOP Class.
instance


The instance of the class. A server may, for example, have three instances of the Nuclear Medicine Class. This value identifies the data with a specific instance.
dataSet


A DicomDataSet object that contains the Data Set which contains the new information to set.

            
            

            
            
            
            
Remarks
Calling this method generates a call to OnReceiveNSetRequest on the SCP. The SCP should respond by calling SendNSetResponse which will generate a call to OnReceiveNSetResponse.
