pythonnet

This fork of http://sourceforge.net/projects/pythonnet/ allows easy calling of python functions from C#.

All calls to python should be inside a "using (Py.GIL()) {/* Your code here */}" block.

Import python modules using dynamic mod = Py.Import("mod"), then you can call functions as normal, eg

mod.func(args).

Use mod.func(args, Py.kw("keywordargname", keywordargvalue)) to apply keyword arguments.

All python objects should be declared as 'dynamic' type.

Mathematical operations involving python and literal/managed types must have the python object first, eg np.pi*2 works, 2*np.pi doesn't.

EG:

static void Main(string[] args)

{

using (Py.GIL()) {

dynamic np = Py.Import("numpy");

dynamic sin = np.sin;

Console.WriteLine(np.cos(np.pi*2));

Console.WriteLine(sin(5));

Console.WriteLine(np.cos(5) + sin(5));

dynamic a = np.array(new List<float> { 1, 2, 3 };

dynamic b = np.array(new List<float> { 6, 5, 4 }, Py.kw("dtype", np.int32));

Console.WriteLine(a.dtype);

Console.WriteLine(b.dtype);

Console.WriteLine(a * b);

Console.ReadKey();

}

}

which outputs:

int32
