want to pass string as true is list have value

Question

I want to pass value as True if some list has value , for example here

if item.Achievements.Count() has value then i need to pass something like this

...
item.Location.City + "|" +True + "|" + item.Soid + "|" +
...

Code is like this

foreach (var item in mgrProfile.GetMemberProfile(context.CurrentMember.MemberProfileSoid).Projects)
{
    bool isdataachivevement = 
    string list = item.Soid+ "|" +
                  item.Soid + "|" +
                  item.ProjectTitle + "|" +
                  item.Role + "|" +
                  item.StartDate.ToShortDateString() + "|" +
                  item.EndDate.value.ToShortDateString() + "|" +
                  item.Location.Country + "|" +
                  item.Location.State + "|" +
                  item.Location.City + "|" +
   // Here is I need to pass as True// if Achievements have data, otherwise false
                  item.Achievements.Count() + "|" +
                  item.Soid + "|" +
                  item.Soid + "|" +
                  item.Soid + "|" +
                  item.Soid + "|" +
                  projectlist.Add(list);
}

Can't you just put: `...+(achievementsHaveData?"true":"false")...` — Matthew Watson, Feb 27 '13 at 10:15
@OscarMederos it feels dirty getting reputation from such an easy answer though :P — Sayse, Feb 27 '13 at 10:22

You can do

(.Count() > 0).toString();

this is correct. Other questions are like: `a == b ? true : false` instead of just `a == b` :) – Oscar Mederos Feb 27 '13 at 10:23
i got error at Nullable object must have a value. at (item.Achievements.Count > 0).ToString(); – Sam Elliott Feb 27 '13 at 10:57
no sorry my mistake it should be like (.Count() > 0).toString(); – Sam Elliott Feb 27 '13 at 11:05

Simply use:

string list = item.Soid+ "|" +
              item.Soid + "|" +
              item.ProjectTitle + "|" +
              item.Role + "|" +
              item.StartDate.ToShortDateString() + "|" +
              item.EndDate.value.ToShortDateString() + "|" +
              item.Location.Country + "|" +
              item.Location.State + "|" +
              item.Location.City + "|" +
              item.Achievements.Any() + "|" + // <--- Here is a solution
              item.Achievements.Count() + "|" +
              item.Soid + "|" +
              item.Soid + "|" +
              item.Soid + "|" +
              item.Soid + "|" +
              projectlist.Add(list);

This will call ToString() on the bool (System.Boolean) which will return either bool.TrueString or bool.FalseString.

replace line with:

(item.Achievements.Count() > 0) ? "true" : "false"

or better as suggested in comments if you are using .NET list

item.Achievements.Any()

better choice would be to use item.Achievements.Any() – Michal Franc Feb 27 '13 at 10:17

Count is a property:

...
item.Location.City + "|" +
item.Achievements.Count > 0 ? "true" : "false" + "|" +
item.Soid + "|" +
...

if `Achievements` is an `IEnumerable`, then it won't be a property. – Oscar Mederos Feb 27 '13 at 10:19
@OscarMederos it is a list. Please read the question carefully: "I want to pass value as True **if some list has value** " – Andrey Gordeev Feb 27 '13 at 10:20

Operator '>' cannot be applied to operands of type 'string' and 'int' – Sam Elliott Feb 27 '13 at 10:32
@SamElliott That's because he's missing a parenthesis in his long expression with `+`. – Jeppe Stig Nielsen Feb 27 '13 at 10:35
