SendNGetRequest Method (DicomNet)

Example 







Leadtools.Dicom.Networking Namespace > DicomNet Class : SendNGetRequest 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.
An array of the attributes to get. The attributes must be specified using the Data Element Tags. For a list of available Data Element Tags, refer to Data Element Tag Values.
The number of attributes being requested.
Sends an N-GET-REQ message to a peer member of a connection. .NET support WinRT support

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.
attributes
An array of the attributes to get. The attributes must be specified using the Data Element Tags. For a list of available Data Element Tags, refer to Data Element Tag Values.
count
The number of attributes being requested.
Remarks
Calling this method generates a call to IDicomEvents.OnReceiveNGetRequest on the SCP. The SCP should respond by calling SendNGetResponse which will generate a call to IDicomEvents.OnReceiveNGetResponse.
