Example

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);

      byte[] userInformationData = associate.GetUserInformationData(0); 
      Debug.Assert(userInformationData[0] == 88); 
      associate.SetUserInformation(0, 3, new byte[] { 56 }); 
      userInformationData = associate.GetUserInformationData(0);
