List of object - combining condition check within the list with local variables outside of it

Question

Continuation of previous question linq where list contains any in list

I have a list of objectA Where ObjectA has 2 properties - string action,bool valid

Ex action =abc, valid = true
action xyz , valid = false

etc

I have two local variables

string actiontocheck ="abc"

string validitychecker ="somevalidvalue" // it can be something else too

I want to check something like Iterate through list .

if any of the action in the list contains actiontocheck and 
the corresponding valid flag is true, 

if(validitychecker == "somevalidvalue")
  set flag to false

What I have tried

 if (List1.Any(a => (a.Action.Contains(actiontocheck)) && a.valid)
        {
            if (validitychecker == "somevalidvalue")
            {
                Ignore = true;
            }
        }

What have you tried? A quick google should point you to `Any` or `Select` (your req is slightly vague) — Justin Pihony, Mar 04 '14 at 05:36
added code what i hve tried - the 1st if didnt look feasible with any, — KeenUser, Mar 04 '14 at 05:42
Still not following what the point is, but it looks fine to me — Justin Pihony, Mar 04 '14 at 05:49
the if condition gives an error - Cannot apply && to operands of type bool and system.nullable — KeenUser, Mar 04 '14 at 05:52
try to replace `&& a.valid` with `&& a.HasValue && a.valid.Value` — har07, Mar 04 '14 at 05:58
or you could do `a.valid == true` which will cause the same unboxing — Justin Pihony, Mar 04 '14 at 06:00

The issue is the type of a.valid. There are many ways to solve this issue, but if you know that it will have a value of True or False every time, you should be able to simply write:

if (List1.Any(a => (a.Action.Contains(actiontocheck)) && a.valid.Value)
{
    if (validitychecker == "somevalidvalue")
    {
        Ignore = true;
    }
}
