Extracting Forces from STAAD using DotNet

Question

Hi, 
 Please could someone help me in extracting forces from STAAD using DotNET? 
 Not able to extract Primary LoadCase number for extracting Forces. 
 here is my sample code: 
 ' Get BeamLIST
 Dim myBeamNos As Integer = myStaadObj.Geometry.GetMemberCount

' Get LoadCase Numbers
 Dim myLoadCasesCount As New Integer
 myLoadCasesCount = myStaadObj.Load.GetLoadCombinationCaseCount

'Get Primary Load Case Numbers
 Dim myLoadCaseList() As Integer = Nothing
 myStaadObj.Load.GetLoadCombinationCaseNumbers(myLoadCaseList)
 ReDim myLoadCaseList(myLoadCasesCount)

Dim myLoadCases As Integer = myLoadCaseList(0)

As per your description, you want to extract the primary load case numbers to extract the member forces. But in your code, you have used the commands to extract the combination case numbers. Following is an example of the correct syntax -- 
 1. Extract the total primary load case count in a long variable -- Load.GetPrimaryLoadCaseCount 
 2. Extract the primary load case number and store it in long array -- Load.GetPrimaryLoadCaseNumbers 
 Following is a VBA example of the same-- 
 Dim Lprim As Long 
 Dim Lprimcase() As Long 
 Set suro= GetObject(, "StaadPro.OpenSTAAD") 
 Lprim = suro.Load.GetPrimaryLoadCaseCount 
 ReDim Lprimcase(0 To (Lprim - 1)) As Long 
 suro.Load.GetPrimaryLoadCaseNumbers Lprimcase
