C# How to refer input parameters between //custom additional code//

I don't understand. Whatever code you write in the additional block is necessarily in a different method than the RunScript method. As such that code will have to be encapsulated in a method signature of your own devising. You can choose whatever arguments you want for these methods. For example:

private void DoSomething(DataTree<double> data, double min, double max)
{
  for (int p = 0; p < data.BranchCount; p++)
  {
    List<double> branch = data.Branch(p);
    for (int i = 0; i < branch.Count; i++)
    branch[i] = Math.Min(Math.Max(branch[i], min), max);
  }
}

Dear David,

Thank you for your answer.

I made mistake to explain what I struggle.

I want to make global value in the additional block like this

And, I attach my .gh file.

private void RunScript(DataTree<double> Input, ref object A)
{

etc...

}

// <Custom additional code>

//refering global value
public int num = 4;
public int nnode = (int) Input.Branch(new GH_Path(0))[0];
public int nelem = (int) Input.Branch(new GH_Path(1))[0];
public int nmat = (int) Input.Branch(new GH_Path(2))[0];
public int nprop = (int) Input.Branch(new GH_Path(3))[0];

// </Custom additional code>

I don't think you can set Input to be a 'global' value (a class wide variable), since it is defined as an input of the method runscript. 

But, what you can do is create a declaring another Datatree<double> outside of the method and copying Input into it. 

Would that help?

private void RunScript(DataTree<int> x, ref object A)
{
y = x;
// Do Whatever you want here
A = y;

}

// <Custom additional code>
DataTree<int> y;
