Question

我已经使用c＃向powerpoint插入了一个图像，并且插入了一个超链接到图片并且它的工作正常。但是现在我需要读取我用c＃插入的那张图片的超链接。

然后使用c＃将带有超链接的文本插入powerpoint，并通过以下方法从powerpoint读回超链接。

for (int i = 0; i < presentation.Slides.Count; i++)
        {
            foreach (var item in presentation.Slides[i + 1].Shapes)
            {
                var shape = (PPT.Shape)item;
                if (shape.HasTextFrame == MsoTriState.msoTrue)
                {
                    if (shape.TextFrame.HasText == MsoTriState.msoTrue)
                    {
                        var textRange = shape.TextFrame.TextRange;
                        var text = textRange.Text;

                        string address=textRange.ActionSettings[PPT.PpMouseActivation.ppMouseClick].Hyperlink.Address;
                    }
                }
            }

        }

我在变量地址中获取超链接地址，同样我需要从使用c＃插入PPT的图像中获取超链接。

有可能。??

一种选择是遍历幻灯片上的形状并查看它们是否包含超链接。或者你应该在创建它时给你的图片一个id，然后通过给定的id找到它。

    private void GetHyperlink()
    {
        Microsoft.Office.Interop.PowerPoint.Application objApp = new Microsoft.Office.Interop.PowerPoint.Application();
        objApp.Visible = Microsoft.Office.Core.MsoTriState.msoTrue;
        Presentations objPresSet = objApp.Presentations;
        Presentation p = objPresSet.Open("C:\test.ppt");
        Slide slide = p.Slides[1];
        // or Slide slide = objApp.ActiveWindow.View.Slide;

        for (int i = 1; i <= slide.Shapes.Count; i++)
        {
            //If the hyperlink address is filled then display it in MessageBox
            if (slide.Shapes[i].ActionSettings[PpMouseActivation.ppMouseClick].Hyperlink.Address != null)
                MessageBox.Show(slide.Shapes[i].ActionSettings[PpMouseActivation.ppMouseClick].Hyperlink.Address);
        }
    }

此代码将显示幻灯片1上的所有超链接。另外，为此目的使用Open XML SDK而不是自动化会很有趣。

我建议你先修改用这样的超链接创建图像的代码：

        //Add a picture
        Shape pic = slide.Shapes.AddPicture(@"C:\Users\Public\Pictures\Sample Pictures\koala.jpg",
        Microsoft.Office.Core.MsoTriState.msoFalse,
        Microsoft.Office.Core.MsoTriState.msoTrue,
        shape.Left, shape.Top, shape.Width, shape.Height);

        //Here you have various options how to distinguish your shape
        pic.Name = "MyPic";
        pic.AlternativeText = "Koala";
        pic.Tags.Add("MyPic", "@http://www.google.com/");

        //adding hyperlink, etc...
        pic.ActionSettings[PpMouseActivation.ppMouseClick].Hyperlink.Address =@"http://www.google.com/"

然后，当您阅读文件时，您可以使用标签或名称来区分形状：

            //tags check
            if (slide.Shapes[i].Tags.Count > 0 && slide.Shapes[i].Tags["MyPic"]!=null && slide.Shapes[i].ActionSettings[PpMouseActivation.ppMouseClick].Hyperlink.Address != null)
                MessageBox.Show(slide.Shapes[i].ActionSettings[PpMouseActivation.ppMouseClick].Hyperlink.Address);
            //or
            //name check
            if (slide.Shapes[i].Name.Equals("MyPic", StringComparison.InvariantCultureIgnoreCase) && slide.Shapes[i].ActionSettings[PpMouseActivation.ppMouseClick].Hyperlink.Address != null)
                MessageBox.Show(slide.Shapes[i].ActionSettings[PpMouseActivation.ppMouseClick].Hyperlink.Address);
