C# 用Microsoft.Office.Interop.PowerPoint类库操作PPT

前言：最近由于项目需求，需要使用此类库对PPT进行操作
1.引用 Microsoft.Office.Interop.PowerPoint和 Microsoft.Office.Core
2.PPT操作

打开PPT

//PPT应用程序变量
 Application application= = new Microsoft.Office.Interop.PowerPoint.Application();
 //PPT文档变量，打开PPT ，path为PPT文档路径
 Presentation ppt = application.Presentations.Open(path, MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse);
 

获取文字内容

1. 所有文字

               List<string> StrList=new List<string>();
               foreach (Microsoft.Office.Interop.PowerPoint.Slide slide in ppt.Slides)
                {            
                    //遍历所有元素
                    foreach (Microsoft.Office.Interop.PowerPoint.Shape shape in slide.Shapes)
                    {
                        //判断是否是文字
                        if (shape.HasTextFrame == OFFICECORE.MsoTriState.msoTrue && shape.TextFrame.HasText == OFFICECORE.MsoTriState.msoTrue)
                        {
                            StrList.add(shape.TextFrame.TextRange.Text.ToString());                           
                        }                   
                    }                                   
                }
                

2. 指定Slides的文字内容

                List<string> list = new List<string>();    
                Microsoft.Office.Interop.PowerPoint.Slide slid = ppt.Slides[Index];
                //遍历所有元素
                foreach (Microsoft.Office.Interop.PowerPoint.Shape shape in slid.Shapes)
                {
                    //判断元素是文字
                    if (shape.HasTextFrame == OFFICECORE.MsoTriState.msoTrue && shape.TextFrame.HasText == OFFICECORE.MsoTriState.msoTrue)
                    {
                        list.Add(shape.TextFrame.TextRange.Text.ToString());
                    }
                }             
                return list;
                

获取指定幻灯片的所有图片

                Microsoft.Office.Interop.PowerPoint.Slide slid = ppt.Slides[Index];
                //遍历所有元素            
                foreach (Microsoft.Office.Interop.PowerPoint.Shape shape in slid.Shapes)
                {           
                    //判断是否是图片
                    if (shape.Type == OFFICECORE.MsoShapeType.msoPicture)
                    {
                            //复制到剪切板
                            shape.Copy();
                            //拿到图片数据                          
                            Image img = (Image)Clipboard.GetData(DataFormats.Bitmap); 
                    }
                }
                

获取指定幻灯片中的表格,转换成DataTable

                //找到指定Index的元素
                Microsoft.Office.Interop.PowerPoint.Slide slide = ppt.Slides[Index];
                //遍历所有元素
                foreach (Microsoft.Office.Interop.PowerPoint.Shape shape in slide.Shapes)
                {
                    //判断是否是表格
                    if (shape.HasTable == MsoTriState.msoTrue)
                    {
                        DataTable dt = new DataTable();
                        //遍历元素，转换成dataTable
                        for (int k = 0; k < shape.Table.Columns.Count; k++)
                        {
                            DataColumn dc = new DataColumn();
                            dt.Columns.Add(dc);
                        }
                        for (int i = 0; i < shape.Table.Rows.Count; i++)
                        {
                            DataRow dr = dt.NewRow();
                            for (int j = 0; j < shape.Table.Columns.Count; j++)
                            {
                                dr[j] = shape.Table.Cell(i + 1, j + 1).Shape.TextFrame.TextRange.Text;

                            }
                            dt.Rows.Add(dr);
                        }                     
                    }
                }
