How do I check if the class it is empty?

I cant get this right. I need to know if there is something in my:
person.barnPnr[i]

but if I write person.barnPnr[i] and then . I can get a Count but that looks like Count< > so how do I check if there is something in it or not?

int i = 0;
                //while (person.barnPnr[i]. > 0)
                while(person.barnPnr.Count<int> != 0)
                {
                    message = message + person.barnForNamn;
                    message = message + "\n";
                    message = message + person.barnEfterNamn;
                    message = message + "\n";
                    message = message + person.barnPnr;
                    i++;
                }

Did you check person[i].barnPnr != 0 ?

philipjonathan

Is barnPnr a List<>? Do you wish to iterate through it?
for (int i = 0; i < person.barnPnr.Count; i++)
{
YourObjectTypeHere barnPnr = person.barnPnr[i];
...
}

if ( person != null && person.barnPnr != null && person.barnPnr.Count > 0 )
{
// Your Logic... person.barnPnr[0]
}

Dhaest:
while (person.barnPnr[i] != 0)
//error. Cant check string to int

-------------------------------------------
philipjonathan:
barnPnr is a public List<String> barnPnr;

for (int i = 0; i < person.barnPnr.Count; i++)

//error Error 1 Operator '<' cannot be applied to operands of type 'int' and 'method group' C:\Documents and Settings\MFL\Dokumenter\Visual Studio 2008\Projects\WebApplication1\WebApplication1\Class1.cs 37 33 WebApplication1

-----------------------------
HarryNS:
while(person.barnPnr != null)
works but I need to iterat throw the list util it is empty
