Calling functions with a variable number of arguments

Flee supports calling functions with a variable number of arguments. Flee will detect calls to functions marked with the params keyword and will package all given arguments into an array of the params type.

Here's an example that shows how to do this:

// Declare a class with some static functions
public static class CustomFunctions
   // Declare a function that takes a variable number of arguments
   public static int Sum(params int[] args)
      int sum = 0;

      foreach (int i in args)
         sum += i;

      return sum;

Once we have declared the function, we can use it in an expression:

ExpressionContext context = new ExpressionContext();

IDynamicExpression e = context.CompileDynamic("sum(1,2,3,4,5,6)");
int result = (int)e.Evaluate();
