Microsoft.Office.Interop.PowerPoint 根据模板导出PowerPoint

环境：Visual Studio 2015

---

场景：现有一个PPT模板，需要把业务数据插到PPT里面。

思路：在PPT模板里面做好标识，然后建一个Dictionary，key是PPT里面的标识，value是要替换的内容，通过Microsoft.Office.Interop.PowerPoint把数据插入PPT模板。

---

实施：

需要要导入Microsoft.Office.Interop.PowerPoint、Microsoft.Office.Core，用[NuGet]管理就好了。

引入命名空间

using Microsoft.Office.Core;
using Microsoft.Office.Interop.PowerPoint;

---

代码：

数据组织

            Dictionary<string, string> keyValues = new Dictionary<string, string>();
            keyValues.Add("idField", "101");
            keyValues.Add("titleField", "测试101");
            keyValues.Add("nameField", "郑同学");
            keyValues.Add("funField", "");
            keyValues.Add("proField", "");
            keyValues.Add("sproField", "");

替换PPT文本

using Microsoft.Office.Core;
using Microsoft.Office.Interop.PowerPoint;

    public class PowerPointHelper
    {

            Application pptApp;

            Presentation presentation = null;
            pptApp = new Application();

                presentations = pptApp.Presentations;
                //打开PPT
                presentation = presentations.Open(filePath, MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse);
                //替换模板PPT中的文本
                foreach (Microsoft.Office.Interop.PowerPoint.Slide slide in presentation.Slides)
                {
                    foreach (Microsoft.Office.Interop.PowerPoint.Shape shape in slide.Shapes)
                    {
                        ReplaceShapeText(shape, keyValues);
                    }
                }
                
                //保持文件
                path = AppDomain.CurrentDomain.BaseDirectory + "PPT/test-" + DateTime.Now.ToString("yyyyMMddhhmmss") + ".pptx";
                presentation.SaveAs(AppDomain.CurrentDomain.BaseDirectory + path);
            }
            catch (Exception ex)
            {
                throw new Exception(ex.Message);
            }
            finally
            {
                try
                {
                    presentation.Close();
                    pptApp.Quit();
                }
                catch (Exception) { }
            }
            return path;
        }

                    }
                }
            }
        }

    }
}

另外可能有事还需要插入图片之类的，请看下面

        public static string EditPowerPoint(string filePath, Dictionary<string, string> keyValues)
        {
            string path = "";
            Application pptApp;
            Presentations presentations = null;
            Presentation presentation = null;
            pptApp = new Application();
            try
            {
                presentations = pptApp.Presentations;
                presentation = presentations.Open(filePath, MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse);
                //插入图片
                if (keyValues.ContainsKey("UserProfileUrl") && keyValues["UserProfileUrl"] != null)
                {
                    try
                    {
                        presentation.Slides[1].Shapes.AddPicture(keyValues["UserProfileUrl"], Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoTrue, 588, 88, 115, 98);
                    }
                    catch { }
                }
                if (keyValues.ContainsKey("Image1") && keyValues["Image1"] != null)
                {
                    try
                    {
                        presentation.Slides[1].Shapes.AddPicture(keyValues["Image1"], Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoTrue, 5, 290, 238, 206);
                    }
                    catch { }
                }
                if (keyValues.ContainsKey("Image2") && keyValues["Image2"] != null)
                {
                    try
                    {
                        presentation.Slides[1].Shapes.AddPicture(keyValues["Image2"], Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoTrue, 370, 290, 238, 206);
                    }
                    catch { }
                }
                //Hyperlink h = 
                path = AppDomain.CurrentDomain.BaseDirectory + "PPT/test-" + DateTime.Now.ToString("yyyyMMddhhmmss") + ".pptx";
                presentation.SaveAs(AppDomain.CurrentDomain.BaseDirectory + path);
            }
            catch (Exception ex)
            {
                throw new Exception(ex.Message);
            }
            finally
            {
                try
                {
                    presentation.Close();
                    pptApp.Quit();
                }
                catch (Exception) { }
            }
            return path;
        }

注意了，Slides下标是从1开始的

关于怎么向PPT中添加超链接，目前好像是不能直接往PPT里面插入超链接的，但是可以预先在PPT设好超链接，然后在代码中替换Hyperlink对象的地址和显示文本，通过这种方式达到我们的目的。

                foreach (Hyperlink h in presentation.Slides[1].Hyperlinks)
                {
                    if (h.Address == "http://test/Home/Login" && keyValues.ContainsKey("AttachmentUrl"))
                    {
                        h.Address = keyValues["AttachmentUrl"];//"https://www.baidu.com/";
                        h.TextToDisplay = keyValues["AttachmentField"];
                    }
                }
