We don't know what you are doing next, but maybe you don't need an array. If it's going into another linq statement, or foreach, then just keep it as it is, most simply by using var.

var sortedCopy = myArray.OrderBy(i => i);

foreach(var item in sortedCopy)
{
   //print out for example
}

This allows linq to be as lazy as possible. If you always cast ToArray or ToList then it has no choice than to evaluate then and there, and allocate memory for the result.
