使用c#替换电源点中的图像

在powerpoint中，我放置了一些图表，其中每个图表都包含不同的guid。我已经将GUID设置为他们的超链接。当点击刷新按钮时，我会找到形状，然后从每个图像中获取我保存为超链接的guid，使用该guid将用该形状中的旧图像替换最近的图像。

foreach (var shape in presentation.Slides[slideno].Shapes)
                {
                    var slide = (PPT.Slide)item;
                    if (j <= shapeCount)
                    {
                        string[] address = new string[] { };
                        string dskj = slide.Shapes[j].Name;
                        if (slide.Shapes[j].Name.Equals("DIAGRAM")//, StringComparison.InvariantCultureIgnoreCase)
                         && slide.Shapes[j].ActionSettings[PPT.PpMouseActivation.ppMouseClick].Hyperlink.Address != null)
                        {
                            address = slide.Shapes[j].ActionSettings[PPT.PpMouseActivation.ppMouseClick].Hyperlink.Address.Split('*');
                            string Type = address[0];
                            string Guid = address[1];
                            if (Type == "D")
                            {
                                Session.path = presentation.Path;
                                if (Session.path != "")
                                    Session.Repository.GetProjectInterface().PutDiagramImageToFile(address[1], Session.path + "''" + address[1] + ".jpg", 1);
                                bool diagrm = false;
                                try
                                {
                                    EA.Diagram diag = Session.Repository.GetDiagramByGuid(Guid);
                                    diagrm = true;
                                }
                                catch
                                {
                                    continue;
                                }
                                if (diagrm)
                                {
                                    float Shapeleft = slide.Shapes[j].Left;
                                    float Shapetop = slide.Shapes[j].Top;
                                    float Shapewidth = slide.Shapes[j].Width;
                                    float Shapeheight = slide.Shapes[j].Height;

                                    slide.Shapes[j].Delete();
                                    PPT.Shape pic = slide.Shapes.AddPicture(Session.path + "''" + Guid + ".jpg", Microsoft.Office.Core.MsoTriState.msoFalse,
                                     Microsoft.Office.Core.MsoTriState.msoTrue, Shapeleft, Shapetop, Shapewidth, Shapeheight);
                                    pic.Name = "DIAGRAM";
                                    pic.ActionSettings[PPT.PpMouseActivation.ppMouseClick].Hyperlink.Address = "D*" + Guid;
                                }
                            }
                        }
                    }

使用上面的代码，一切都很好。

address = slide.Shapes[j].ActionSettings[PPT.PpMouseActivation.ppMouseClick].Hyperlink.Address

在address中，我会得到当前图像的超链接地址，但现在我的问题是，如果我在同一张幻灯片中有两个图像，那么当它在形状内循环时，它只为两个图像提供相同的超链接。

**注意：**如果幻灯片中只有一个图像，则一切正常。
