The following example converts an array of Int64 values to Boolean values.

long[] numbers = { Int64.MinValue, -2016493, -689, 0, 6121, 
                   403890774, Int64.MaxValue };
bool result;

foreach (long number in numbers)
{
   result = Convert.ToBoolean(number);                                 
   Console.WriteLine("{0,-26:N0}  -->  {1}", number, result);
}
// The example displays the following output: 
//       -9,223,372,036,854,775,808  -->  True 
//       -2,016,493                  -->  True 
//       -689                        -->  True 
//       0                           -->  False 
//       6,121                       -->  True 
//       403,890,774                 -->  True 
//       9,223,372,036,854,775,807   -->  True
