I am using C # for secondary development of interference detection function. How should I call to display the interference entity

object[] vInts = null;
int i = 0;
int j = 0;
IInterference interference = default(IInterference);
object vIntComps = null;
object[] vComps = null;
Component2 comp = default(Component2);
double vol = 0;
object vTrans = null;
bool ret = false;
SldWorks swApp = (SldWorks)Marshal.GetActiveObject("Sldworks.Application")
