{ 
   TwainSession session = new TwainSession(); 
   session.Startup(parent, "manufacturer", "productFamily", "version", "application", TwainStartupFlags.None); 
 
 
   TwainCapability twCap = session.GetCapability(TwainCapabilityType.ImageUnits, TwainGetCapabilityMode.GetValues); 
 
   if (twCap.Information.ContainerType == TwainContainerType.Enumeration) 
   { 
      TwainEnumerationCapability enumCap = twCap.EnumerationCapability; 
 
      for (int i = 0; i < enumCap.Count; i++) 
      { 
         object capVal = enumCap.GetValue(i); 
         string msg = string.Format("Capability Value({0}) = {1}", i, capVal.ToString()); 
         MessageBox.Show(msg); 
      } 
   } 
   else 
      MessageBox.Show("Container type is not enumeration"); 
}

Imports Leadtools

   Dim session As TwainSession = New TwainSession() 
   session.Startup(parent, "manufacturer", "productFamily", "version", "application", TwainStartupFlags.None) 
 
   Dim twCap As TwainCapability = session.GetCapability(TwainCapabilityType.ImageUnits, TwainGetCapabilityMode.GetValues) 
 
   If twCap.Information.ContainerType <> TwainContainerType.Enumeration Then 
      Dim enumCap As TwainEnumerationCapability = twCap.EnumerationCapability 
      Dim i As Integer 
 
      For i = 0 To enumCap.Count - 1 
         Dim capVal As TwainCapabilityValue = CType(enumCap.GetValue(i), TwainCapabilityValue) 
         Dim msg As String = String.Format("Capability Value(%d) = %s", i, capVal.ToString()) 
         MessageBox.Show(msg) 
      Next
