Hi,

I'm using SW 2011 SP3 and SW 2013 SP4.

I'm trying to get all components from big assembly and in the end I get different result of number children.

For SW 2011 the result is 7373 components for SW 2013 the result is 1374 components.

Can you explain why I have different results? API for getting components was changed for SW 2011 and SW 2013?

Take a look at the code below, please:   
  
Object swDocSpecificationObj = swApp.GetOpenDocSpec(fileName);
  
var swDocSpecification = (IDocumentSpecification)swDocSpecificationObj;
   swDocSpecification.Silent = true;
   swDocSpecification.ReadOnly = true;  
   swDocSpecification.UseLightWeightDefault = false;     
   swDocSpecification.LightWeight = false;
IModelDoc2 swDoc = swApp.OpenDoc7(swDocSpecificationObj); // I see here different time of loading for SW 2011 and 2013, maybe this method was modified?

 var swModel = (ModelDoc2)swApp.ActiveDoc;

 var swConfMgr = (ConfigurationManager)swModel.ConfigurationManager;  
var activeConfig = (Configuration)swConfMgr.ActiveConfiguration;  
var rootComponent = (Component2)activeConfig.GetRootComponent();  
var numComponents = calcComponents(rootComponent, 1);

  
int calcComponents(IComponent2 comp, long nLevel)
{ 
     int numComponents = 1;  
     string sPadStr = " ";  
     long i = 0;  
     for(i = 0; i <= nLevel - 1; i++)
     {
          sPadStr = sPadStr +  " "; 
     }
     var children = (object[])comp.GetChildren();  
     
for(i = 0; i < children.Length; i++)
{ 
          Component2 swChildComp = (SW.Component2)children[i];   
          Debug.Print(sPadStr + "+" + swChildComp.Name2 + " <" + swChildComp.ReferencedConfiguration + ">");
         numComponents += calcComponents(swChildComp, nLevel + 1); 
    }
    return numComponents;
 }
Thanks in advance
