从VB集合转换为Int

Question

Do you see wrong code in here? I am getting a InvalidCaseException on the foreach loop that is using an INT variable:

 Microsoft.VisualBasic.Collection oHeaders = GetFieldIdsByName(msREPORT_HEADER);

foreach (int FieldId in oHeaders)

Answer 1

foreach (object FieldId in oHeaders)
{
    int value = Int32.Parse(FieldId.ToString());
}

Answer 2

foreach (int i in oHeaders.Cast<int>())
{
     //TODO: your action here.
}
