using Leadtools; 
using Leadtools.Twain; 
 
public void TwainArrayCapabilityGetValueExample(IntPtr parent) 
{ 
   TwainSession session = new TwainSession(); 
   session.Startup(parent, "manufacturer", "productFamily", "version", "application", TwainStartupFlags.None); 
 
   TwainCapability twCap = session.GetCapability(TwainCapabilityType.ImageFilter, TwainGetCapabilityMode.GetValues); 
 
   if (twCap.Information.ContainerType == TwainContainerType.Array) 
   { 
      TwainArrayCapability arrayCap = twCap.ArrayCapability; 
 
      for (int i = 0; i < arrayCap.Count; i++) 
      { 
         TwainCapabilityValue capVal = (TwainCapabilityValue)arrayCap.GetValue(i); 
         string msg = string.Format("Capability Value(%d) = %s", i, capVal.ToString()); 
         MessageBox.Show(msg); 
      } 
   } 
   else 
      MessageBox.Show("Container type is not array"); 
 
   session.Shutdown(); 
}

   Dim twCap As TwainCapability = session.GetCapability(TwainCapabilityType.ImageFilter, TwainGetCapabilityMode.GetValues) 
 
   If twCap.Information.ContainerType <> TwainContainerType.Array Then 
      Dim arrayCap As TwainArrayCapability = twCap.ArrayCapability 
      Dim i As Integer 
 
      For i = 0 To arrayCap.Count - 1
