ASP.NET 导出PPT

　　前一段时间因工作需要，需增加ppt数据的导出下载。发现网络上这方面资料并不是很多，零零散散地找到一些相关的资料，经过自己的试验，终于完成相关功能。应博友要求，在此分享下我的经验，不好之处还望大家多多指出。

　　在做之前，首先需要添加相关引用Microsoft.Office.Interop.PowerPoint.dll。

using PowerPoint = Microsoft.Office.Interop.PowerPoint;

　　操作PPT代码如下：

        public void createPPT()
        {
            try
            {
                //ppt存储路径
                string path = string.Format("{0}/{1}.ppt", Server.MapPath("."), DateTime.Now.Ticks.ToString());
                //ppt引用的模版路径
                string MyTemplateFile = "d:\\test.pot";
                PowerPoint.ApplicationClass MyApp;
                PowerPoint.Presentations MyPresSet;
                PowerPoint._Presentation MyPres;
                PowerPoint.Shape objShape;
                PowerPoint.Slides objSlides;
                PowerPoint._Slide MySlide;
                PowerPoint.TextRange objTextRng;
                PowerPoint.Table table = null;
                MyApp = new PowerPoint.ApplicationClass();
                //如果已存在，则删除
                if (File.Exists((string)path))
                {
                    File.Delete((string)path);
                }
                Object Nothing = Missing.Value;
                //套用模版
                MyPres = MyApp.Presentations.Open(MyTemplateFile, MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse);
                MyPresSet = MyApp.Presentations;
                objSlides = MyPres.Slides;

                //创建第一张PPT ppLayoutTitle指定模板首页
                MySlide = objSlides.Add(1, PowerPoint.PpSlideLayout.ppLayoutTitle);
                //添加一行文字（left:10,top:110,width:700,height:400）
                objTextRng = MySlide.Shapes.AddLabel(MsoTextOrientation.msoTextOrientationHorizontal, 10, 110, 700, 400).TextFrame.TextRange;
                objTextRng.Text = " PPT";
                objTextRng.Font.Color.RGB = 0x66CCFF; //设置字的颜色
                objTextRng.Font.Size = 42; //字号
                
                //创建第二张PPT ppLayoutBlank指定无标题页
                MySlide = objSlides.Add(2, PowerPoint.PpSlideLayout.ppLayoutBlank);
                //插入图片
                MySlide.Shapes.AddPicture("1.jpg", MsoTriState.msoFalse, MsoTriState.msoTrue, 110, 140, 500, 300);
                
                //创建第三张PPT ppLayoutTitleOnly指定仅有标题页
                MySlide = objSlides.Add(3, PowerPoint.PpSlideLayout.ppLayoutTitleOnly);
                objTextRng = MySlide.Shapes[1].TextFrame.TextRange;
                objTextRng.Text = "目录";
                objTextRng.Font.Size = 32;
                //插入图片
                MySlide.Shapes.AddPicture("1.jpg", MsoTriState.msoFalse, MsoTriState.msoTrue, 110, 140, 500, 300);
                
                //创建第四张PPT
                MySlide = objSlides.Add(3, PowerPoint.PpSlideLayout.ppLayoutBlank);
                //添加一个表格
                objShape = MySlide.Shapes.AddTable(3, 3, 105, 150, 400, 100);
                table = objShape.Table;
                for (int i = 1; i <= table.Rows.Count; i++)
                {
                    for (int j = 1; j <= table.Columns.Count; j++)
                    {
                        table.Cell(i, j).Shape.TextFrame.TextRange.Font.Size = 12;
                        table.Cell(i, j).Shape.TextFrame.TextRange.Text = string.Format("[{0},{1}]", i, j);
                    }
                }
                
                
                //保存格式
                PowerPoint.PpSaveAsFileType format = PowerPoint.PpSaveAsFileType.ppSaveAsDefault;
                //内容保存
                MyPres.SaveAs(path, format, Microsoft.Office.Core.MsoTriState.msoFalse);
                //关闭excelDoc文档对象
                MyPres.Close();
                //关闭excelApp组件对象
                MyApp.Quit();
            }
