Linq OfType Extension Operator

Suppose you have an array of type object,

Object[] arrobj = { 2.0, null, "one", 4, "ten", 6, "one", 10.0 }; 

var doubles = arrobj.OfType<double>(); 
  
    Console.WriteLine("Numbers stored as doubles:"); 
    foreach (var temp in doubles) 
    { 
        Console.WriteLine(temp); 
    }

Numbers stored as doubles:
2.0
10.0

Thanks and Regards
