How to programmatically read and change slide notes in PowerPoint

问题

How do you get the Notes text from the current PowerPoint slide using C#?

回答1:

I believe this might be what you are looking for:

string s = slide.NotesPage.Shapes[2].TextFrame.TextRange.Text
slide.NotesPage.Shapes[2].TextFrame.TextRange.Text = "Hello World"

Here is my code that I use for getting the slide notes. Still developing it, but seems to do the trick for the time being. Even in my simple test PPT the slide notes are not always the [2] element in the shapes array, so it is important to check.

    private string GetNotes(Slide slide)
    {
        if (slide.HasNotesPage == MsoTriState.msoFalse)
            return string.Empty;

        string slideNodes = string.Empty;
        var notesPage = slide.NotesPage;
        int length = 0;
        foreach (Shape shape in notesPage.Shapes)
        {
            if (shape.Type == MsoShapeType.msoPlaceholder)
            {
                var tf = shape.TextFrame;
                try
                {
                    //Some TextFrames do not have a range
                    var range = tf.TextRange;
                    if (range.Length > length)
                    {   //Some have a digit in the text, 
                        //so find the longest text item and return that
                        slideNodes = range.Text;
                        length = range.Length;
                    }
                    Marshal.ReleaseComObject(range);
                }
                catch (Exception)
                {}
                finally
                { //Ensure clear up
                    Marshal.ReleaseComObject(tf);
                }
            }
            Marshal.ReleaseComObject(shape);
        }
        return slideNodes;
    }
