You can try this:

>>> import System
>>> array = System.Array
>>> x = array[float](range(5))
>>> x
System.Double[](0.0, 1.0, 2.0, 3.0, 4.0)


>>> System.Array.CreateInstance(float, 5)
System.Double[](0.0, 0.0, 0.0, 0.0, 0.0)
>>> x = System.Array.CreateInstance(float, 5)
>>> x[0] = 10

Subject: [IronPython] Array element access of C# extension.

Hello group,

I wish to access each element value of single-dimension array in C# extension
from IP. For example, a static method foo.goo defined in C# code,

// fooLib.cs
using System;
namespace fooLib
  public static class foo
    public static void goo(int n, double[] x, double[] y)
      for(int i=0; i<n; i++)
          x[i] = i;
          y[i] = 1.0/i;

can be accessed from C# main program:

// testing.cs
using System;
using fooLib;
class testing
  public static void Main()
    int n = 10;
    double [] x = new double[n];
    double [] y = new double[n];
    foo.goo(n, x, y);
    Console.WriteLine("x[9],y[9]="+x[9]+", "+y[9]);

I struggled to write an IP code similar to testing.cs but not done,
because of Python has no corresponding simple array data type.

Can anybody show me how I can access each element value of C#
extention like fooLib.cs from IP code?

Thanks in advance,
