Programmatically Saving Grasshopper Files

I received a random question in my email about how to programmatically launch a file dialogue to save a Grasshopper file.

Using a C# component you could drive this with a Boolean Toggle like so:

GH_DocumentIO docIO = new GH_DocumentIO(GrasshopperDocument);
if (save) docIO.Save();

If you want the document to automatically detect whether or not it's been saved and, if it hasn't, immediately launch the file save dialogue, do this:

GH_DocumentIO docIO = new GH_DocumentIO(GrasshopperDocument);
if (GrasshopperDocument.FilePath == null) docIO.Save();

Note that the GrasshopperDocument object exists as a Member in the C# component, otherwise you'd have to call it like this:

GH_Document doc = Grasshopper.Instances.ActiveCanvas.Document
