As in the trading terminal Sterling get a list of orders?

Method in the trading terminal Sterling

Code:

GetOrderList(VARIANT_BOOL bOpenOnly, SAFEARRAY(structSTIOrderUpdate) *arrayOrder, long *lCount);

Such a structure it in Visual Studio

Code:

int GetOrderList([In] bool bOpenOnly, [MarshalAs(UnmanagedType.SafeArray, SafeArraySubType = VarEnum.VT_EMPTY), In, Out] ref Array arrayOrder);

Trying to call it in my application, but I can not understand what I have to do everything to work correctly.
code:

Code:

             Array arrList = new Array[10];
                var d = stiOrderMaint.GetOrderList(false, ref arrList);

Throws an error type of the array is not as expected, try a different
The programming language C #.
Please help me, how do I call this method. Thank you.

 

Code:

public int OrderCount = new int();
public Array OrderList;
public SterlingLib.structSTIOrderUpdate q;
public string id;

OrderList = Array.CreateInstance((typeof(SterlingLib.structSTIOrderUpdate)), 0);

OrderCount = Omaint.GetOptionsOrderList(false, ref OrderList);

q = new structSTIOrderUpdate();

for (int i = 0; i < OrderCount; i++)
                {
q = (SterlingLib.structSTIOrderUpdate)OrderList.GetValue(i);

id = q.bstrUserId.ToString();
}

Hope this helps

 

Code:

public STIEvents events;

events = new STIEvents();

events.SetOrderEventsAsStructs(true);

Forgot that part.

 

Omaint = new STIOrderMaint(); ?

OrderCount = stiOrderMaint.GetOrderList(false, ref OrderList1); - here the error takes.

 

Code:

public STIOrderMaint Omaint;

 

Thank you
