Question

I don’t know how to do the if check condition inside my list,i believe “Lambda Expressions” my help but don’t know

here is my code

List<ResourceBookingEntity> ResourceBookingList = new List<ResourceBookingEntity>();
foreach (var r in query)
{
    ResourceBookingEntity RecourceEntity = new ResourceBookingEntity()
    {

        PRJ_ID = r.PRJ_ID,
        WONUM = r.WONUM,
        JOBDESC = r.JOBDESC,
        SAPCCr = // If r.PRJ_ID =1 or 2 then SAPCCr =r.WONUM 
                        // elseif r.PRJ_ID= 3then SAPCCr =r.JOBDESC
        };
    ResourceBookingList.Add(RecourceEntity);

Here what am trying to do,i have linq query that returns a result based on r.PRJ.ID value am trying to fill SAPCCr value.

If r.PRJ_ID = 1 or 2 then 
SAPCCr = r.WONUM 
elseif r.PRJ_ID = 3
then 
SAPCCr = r.JOBDESC

Thanks in Advance

You can chain conditional operators:

SAPCCr = (r.PRJ_ID == 1 || r.PRJ_ID == 2) ?  r.WONUM :  
         r.PRJ_ID == 3 ?  r.JOBDESC : null;
