Question

I have two lists List<WorkOrder> and List<PlannedWork> I would like join the two lists on the workorder number as detailed below. In other words I have a list of planned work but I need to know the description of the work for the workOrderNumber.

I am new to both linq and lambda expressions, and I haven’t quite got my head wrapped around them yet.

class WorkOrder
{
    public int WorkOrderNumber { get; set; }
    public string WorkDescription { get; set; }
}

class PlannedWork
{
    public int WorkOrderNumber { get; set; }
    public DateTime ScheduledDate { get; set; }
}

It sounds like you want something like:

var query = from order in workOrders
            join plan in plans
                 on order.WorkOrderNumber equals plan.WorkOrderNumber
            select new
            {
                order.WorkOrderNumber,
                order.Description,
                plan.ScheduledDate
            };
