All what I had to do was to check whether , my List<> object contains any object with a SelectedDate (a property of the object) having a certain value. And I did not want to loop in the List and find out . (tomorrow there may be 10000 items in my list , and a loop would be very very slow). I found that a List exposes a property called Exits() which can do the trick for me .....
static
void Main(string[] args)
{
List<Dinosour> _DinoList = new List<Dinosour>();
Dinosour d1 = new Dinosour();
d1.Name=
"TREX";
d1.Gender=
"M";
_DinoList.Add(d1);
Dinosour d2 = new Dinosour();
d2.Name =
"Bronto";
d2.Gender =
"F";
_DinoList.Add(d2);
Dinosour d3 = new Dinosour();
d3.Name =
"Raptor";
d3.Gender =
"F";
_DinoList.Add(d3);
bool
c= _DinoList.Exists(CheckIfExists);
Console.WriteLine("Dino :" + c);
Console.ReadKey();
}
//****************************
private
static bool CheckIfExists(Dinosour d)
{
if (d.Name == "TREX")
return true;
else
return false;
}
//************************
public
class Dinosour
{
private string myVar;
public string Name
{
get { return myVar; }
set { myVar = value; }
}
private string _Gender;
public string Gender
{
get { return _Gender; }
set { _Gender = value; }
}
}
However One disadvantage , i found was that the value to be checked needs to be more or less predetermined as the delegate method does not take any other parameters. Any suggestions would be appreciated.....
Cheers...
