SetExtendedData(byte,byte[]) Method

Summary
Sets the extended data associated with the specified Presentation Context.
Syntax
C#
C++/CLI
public void SetExtendedData( 
   byte id, 
   byte[] data 
) 
public: 
void SetExtendedData(  
   byte id, 
   array<byte>^ data 
)  

Parameters

id
Presentation Context ID of the Presentation Context to which to set the extended data. 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.

data
Buffer that contains the data to set.

Remarks

To retrieve the length of the extended data associated with a Presentation Context, call GetExtendedDataLength. To get the extended data associated with a Presentation Context, call GetExtendedData or GetExtendedDataPtr.

Example
C#
using Leadtools; 
using Leadtools.Dicom; 
 
 
void BuildVerifyAssociate() 
{ 
   //Make sure to initialize the DICOM engine, this needs to be done only once  
   //In the whole application 
   DicomEngine.Startup(); 
   using (DicomAssociate associate = new DicomAssociate(true)) 
   { 
      //Role Select 
      associate.AddPresentationContext(1, 0, DicomUidType.VerificationClass); 
      associate.SetRoleSelect(1, true, DicomRoleSupport.Supported, DicomRoleSupport.Unsupported); 
      Debug.Assert(associate.IsRoleSelect(1) == true); 
      Debug.Assert(associate.GetUserRole(1) == DicomRoleSupport.Supported); 
      Debug.Assert(associate.GetProviderRole(1) == DicomRoleSupport.Unsupported); 
 
      //Extended Data 
      associate.SetExtendedData(1, new byte[] { 55 }); 
      Debug.Assert(associate.GetExtendedDataLength(1) == 1); 
      byte[] extendedData = associate.GetExtendedData(1); 
      Debug.Assert(extendedData[0] == 55); 
      // We can also call GetExtendedDataPtr 
 
      //Asynchronous Operations 
      associate.SetAsynchronousOperations(true, 5, 5); 
      Debug.Assert(associate.IsAsynchronousOperations == true); 
      Debug.Assert(associate.InvokedOperationsCount == 5); 
      Debug.Assert(associate.PerformedOperationsCount == 5); 
 
      //User Information 
      associate.AddUserInformation(4, new byte[] { 88 }); 
      Debug.Assert(associate.UserInformationCount == 1); 
      Debug.Assert(associate.GetUserInformationType(0) == 4); 
      Debug.Assert(associate.GetUserInformationDataLength(0) == 1); 
      Debug.Assert(associate.GetUserInformationDataPtr(0) != null); 
      byte[] userInformationData = associate.GetUserInformationData(0); 
      Debug.Assert(userInformationData[0] == 88); 
      associate.SetUserInformation(0, 3, new byte[] { 56 }); 
      userInformationData = associate.GetUserInformationData(0); 
      Debug.Assert(userInformationData[0] == 56); 
      associate.DeleteUserInformation(0); 
   } 
   DicomEngine.Shutdown(); 
}
