Write a 3dm file with c# in Grasshopper

Hi everybody,

I want batch convert some files from R7 to R6 in Grasshopper with C#.
The bool from Rhino.FileIO.File.Write returns false and nothing is written.

private void RunScript(string path, string newPath, ref object A)
  {
    string[] files = Directory.GetFiles(path);    
    Rhino.FileIO.File3dm file  = Rhino.FileIO.File3dm.Read(files[0]);
    
    A = file.Write(newPath, 0);
  }

Could somebody shed some light?

HI @Baris ,
Your code works when I tested it. Maybe something wrong with the inputs

Thanks for your answer @Darryl_Menezes,
strangely, it does not work on my side:

I also tried it running Rhino as administrator- without success.

@Baris what values did you set to the “path” and the “newPath”?

Thanks again @Darryl_Menezes, that was the problem.
Here the code, if someone needs it in future (without any exception handling):

private void RunScript(bool write, string path, string newPath, ref object A)
  {

    string[] files = Directory.GetFiles(path);//Get all files

    for (int i = 0; i < files.Length; i++)
    {
      Rhino.FileIO.File3dm file = Rhino.FileIO.File3dm.Read(files[i]);

      string[] chunks = files[i].Split('\\');
      string name = chunks[chunks.Length - 1];

      string fileName = string.Format("{0}\\{1}." + "3dm", newPath, name + "_R6");
      if(write)
        file.Write(fileName, new  Rhino.FileIO.File3dmWriteOptions() {Version = 6});
    }

  }

Does your GH file have a button?

Yes, just like this

I don’t know why it doesn’t work, but your code worked correctly.

I think the folder is set up incorrectly.

My last reply is the working code. The problem was the path.
Anyway thanks for your reply!
