如何以编程方式阅读和更改PowerPoint中的幻灯片备注

Question

如何使用C＃从当前的PowerPoint幻灯片中获取Notes文本？

Answer 1

我相信这可能就是你要找的东西：

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

Answer 2

这是我用于获取幻灯片备注的代码。仍在开发它，但似乎暂时做了伎俩。即使在我的简单测试PPT中，幻灯片音符并不总是形状数组中的[2]元素，因此检查它是很重要的。

    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;
    }
