如何使用C＃读取功率点图像的超链接 [英] How to read the hyper-link of an image in power Point using c#

问题描述

我已经插入的图片用c＃PowerPoint和已插入超链接，照片和工作perfectly.But现在我需要阅读这是我使用C＃插入的图片的链接。

I have inserted an image to powerpoint using c# and have inserted a hyperlink to the picture and its working perfectly.But now i need to read the hyperlink of that picture which i have inserted using c#.

而我插入文本超链接到PowerPoint中使用C＃，和我用下面的方法读取超链接从PowerPoint中回来了。

Whereas am inserting a text with hyperlink into powerpoint using c# ,and am reading the hyperlink back from the powerpoint by the below method.

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;
                    }
                }
            }

        }

在这里我得到的超级链接地址中的变量的地址后，同样我需要从我所使用C＃插入PPT图像的超链接。

where am getting the hyperlink address in the variable address, likewise i need to get the hyperlink from the image which i have inserted into PPT using c#.

是否有可能。??

推荐答案

一个办法是通过形状在幻灯片上进行迭代，看看他们是否含有超链接。或创建它的时候，然后由指定ID找到它，你应该给你的照片的ID。

One option would be to iterate through Shapes on a Slide and see, whether they contain hyperlink. Or you should give your picture an id when creating it and then find it by the given id.

    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);
        }
    }

这code将显示在幻灯片1所有超链接。
此外，它会是有趣的，使用Open XML SDK用于此目的，而不是自动化。

This code will display all hyperlinks on slide 1. Also it would be interesting to use Open XML SDK for this purpose instead of automation.

有趣的链接：

HTTP：//www.aspose。 COM /文档/显示/ slidesnet /查找+ A +形状+在+ A +滑动

我建议你先修改code，与这样的超链接创建映像：

I suggest you first modify the code that creates the image with hyperlink like this:

        //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，当你阅读文件，您可以使用标签或名称来区分的形状：

Then when you read the file you can use tags or name to distinguish shapes:

            //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);
