Examples

Copy C# 
ViewSchedule areaSchedule = null;

using (Transaction transaction = new Transaction(doc, "Creating Schedule"))
{
    transaction.Start();

    FilteredElementCollector collector = new FilteredElementCollector(doc);
    collector.OfCategory(BuiltInCategory.OST_AreaSchemes);
    //Get first ElementId of AreaScheme.
    ElementId areaSchemeId = collector.FirstElementId();
    if (areaSchemeId != null && areaSchemeId != ElementId.InvalidElementId)
    {
        // If you want to create an area schedule, you must use CreateSchedule method with three arguments. 
        // The value of the second argument must be ElementId of BuiltInCategory.OST_Areas category
        // and the value of third argument must be ElementId of an AreaScheme.
        areaSchedule = Autodesk.Revit.DB.ViewSchedule.CreateSchedule(doc, new ElementId(BuiltInCategory.OST_Areas), areaSchemeId);
    }
    if (null != areaSchedule)
    {
        transaction.Commit();
    }
    else
    {
        transaction.RollBack();
    }
}
Copy VB.NET 
Dim areaSchedule As ViewSchedule = Nothing

Using transaction As New Transaction(doc, "Creating Schedule")
    transaction.Start()

    Dim collector As New FilteredElementCollector(doc)
    collector.OfCategory(BuiltInCategory.OST_AreaSchemes)
    'Get first ElementId of AreaScheme.
    Dim areaSchemeId As ElementId = collector.FirstElementId()
    If areaSchemeId IsNot Nothing AndAlso areaSchemeId <> ElementId.InvalidElementId Then
        ' If you want to create an area schedule, you must use CreateSchedule method with three arguments. 
        ' The value of the second argument must be ElementId of BuiltInCategory.OST_Areas category
        ' and the value of third argument must be ElementId of an AreaScheme.
        areaSchedule = Autodesk.Revit.DB.ViewSchedule.CreateSchedule(doc, New ElementId(BuiltInCategory.OST_Areas), areaSchemeId)
    End If
    If areaSchedule IsNot Nothing Then

Autodesk.Revit.Exceptions ArgumentNullException A non-optional argument was NULL
Autodesk.Revit.Exceptions ModificationForbiddenException The document is in failure mode: an operation has failed, and Revit requires the user to either cancel the operation or fix the problem (usually by deleting certain elements). -or- The document is being loaded, or is in the midst of another sensitive process.
