Newbie qustion about InvokeMember

[Cliff]

All,

I'm not new to C# but I am new to the concept of calling a member
using Interop.

I can access 1 function and properties in an external dll no
problem....but I can't understand how I'm supposed to do something
which in VB seems simple by comparison.

I need to query a property on an object, that property should return a
pointer to an object of a different type.

In this case, I connect to "AppManager " and ask "AppManager " for a
pointer to its "Machines" Object.

I can successfully get Appmanager to return things like its version or
other public Fields, but I can't get it to return what I want.

Here is the code.

try
{
Type tAppMgr =
Type.GetTypeFro mProgID("NetIQO LE.AppManager") ;
object oAppMgr =
System.Activato r.CreateInstanc e(tAppMgr);
tAppMgr.InvokeM ember(
"Logon",
BindingFlags.In vokeMethod,
null, oAppMgr,
new object[] { "CALNTMGT50 1", "QDB", @"removed",
"removed" });

object oVersion = tAppMgr.InvokeM ember("Version" ,
BindingFlags.Ge tProperty, null, oAppMgr, null);

Debug.WriteLine (((string)oVers ion)); // This
works!

// In this below; oMachines stays "null"...ie nothing
is returned.

object oMachines = tAppMgr.InvokeM ember( //
"Machines",
BindingFlags.Ge tProperty | BindingFlags.Ge tField |
BindingFlags.Ig noreCase
, null, oAppMgr, null);

Type tMachines = oMachines.GetTy pe();
object count = tMachines.Invok eMember("Count" ,
BindingFlags.Ge tField, null, oMachines, null);

Debug.WriteLine (count.ToString ());
}
catch (Exception e)
{
Debug.WriteLine (e.InnerExcepti on.Message);
}
As equivalent call in VB would be something like

oMachines = oAppMgr.Machine s

Any help appreciated!

Cliff.
