 PPT.Application ap = new PPT.Application();
            PPT.Presentation pre = null;
            pre = ap.Presentations.Open(mFileName, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoFalse);
            foreach (PPT.Slide mSlide in pre.Slides)
            {
               
                PPT.Hyperlinks links = mSlide.Hyperlinks;
                for (int i = 1; i <= links.Count; i++)
                {
                    PPT.Hyperlink mLink = links[i];

                    mLink.TextToDisplay = mLink.TextToDisplay.Replace(mLink.TextToDisplay,"url");
                    mLink.Address = mLink.Address.Replace(mLink.Address, "url");
                }
}

修改texttodisplay，adress会被赋值为null。这个问题怎么解决？

问题已经解决了是吧？

我测试你的代码没有什么问题，应该是你看错了。

你好，

如果你先在ppt上写一些文字，然后添加一个hyperlink，这样的话，就会重现问题。
