Creating a Brep 'box' with the "CreateFromBox" method

Hi all,

I am quite new to grasshopper plugins development.

Here is what I am trying to do: I have 8 points (as input arguments) which are the location of a ‘box’ corners (edges are not necessarily either parallel or perpendicular).
I found this Bref method CreateFromBox whose description reads: “Constructs new brep from 8 corner points.” and whose syntax is
"public static Brep CreateFromBox(
IEnumerable corners
)"
I am using the grasshopper C# component. I first created a list of points corners containing the input points and create a Brep using the “CreateFromBox” method and corners as argument. But as experts may expect it didn’t work. I tried other ways which were all fruitless.
Could you please tell me how can I use this method? In case you know a better solution, then I would also be pleased to know it as well. The so generated box is to then to be colored after (if you have a hint for me regarding this, then I will also be happy).

Thank you in advance.

Usually when your code does not work, it is better to post it here. Then everyone can see what the problem is; now it is guesswork - your description sounds good, but obviously something is wrong.
If you surround your code with ``` (3x back-tick on a line) it looks like this:

public void SolveInstance(IGH_DataAccess da)
{
// your code here...
}

Thanks for the reply. Here is the code:

private void RunScript(Point3d P0, Point3d P1, Point3d P2, Point3d P3, Point3d P4, Point3d P5, Point3d P6, Point3d P7, ref object A)
  {

    List<Point3d> corners = new List<Point3d>();
    corners.Add(P0);
    corners.Add(P1);
    corners.Add(P2);
    corners.Add(P3);
    corners.Add(P4);
    corners.Add(P5);
    corners.Add(P6);
    corners.Add(P7);

    Brep box = new Brep();
    box = new CreateFromBox(corners);
    
    A = box;

  }

Try this:

Brep box = Rhino.Geometry.Brep.CreateFromBox(corners);
A = box;
