日常開會或者作總結報告的時候咱們一般都會用到PowerPoint演示文稿,咱們能夠在單個幻燈片或者所有幻燈片裏面添加註釋,這樣觀衆能夠從註釋內容裏面獲取更多的相關信息。html
有些朋友不清楚如何在幻燈片裏面添加註釋,下面我跟你們分享一下如何在C#裏面爲幻燈片添加註釋。ide
在這裏我使用了一個免費控件——Free Spire.Presentation,有興趣的朋友能夠下載使用。 spa
須要添加的命名空間:component
using Spire.Presentation; using System.Drawing;
詳細步驟和代碼片斷以下:orm
步驟1:新建一個Presentation對象,從系統裏面加載Presentation文件。htm
Presentation presentation = new Presentation(); presentation.LoadFromFile("sample.pptx");
步驟2:調用CommentAuthorList.AddAuthor(author name, string initials) 方法來添加做者註釋。對象
ICommentAuthor author = presentation.CommentAuthors.AddAuthor("E-iceblue", "comment:");
步驟3:調用Call presentation.Slides[].AddComment() 方法來給某一張特定幻燈片添加註解。註釋的類包含不少信息,像添加註釋的做者、添加註釋的時間、添加註釋的位置和註釋的內容。blog
presentation.Slides[1].AddComment(author, "This part is pretty important. Please pay attention to it", new System.Drawing.PointF(42, 4), DateTime.Now);
步驟4:保存並從新打開Presentation演示文稿。get
presentation.SaveToFile("PPTwithcomment.pptx", FileFormat.Pptx2010); System.Diagnostics.Process.Start("PPTwithcomment.pptx");
效果圖:string
所有代碼:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using Spire.Presentation; namespace PPTComment { class Program { static void Main(string[] args) { //create PPT document and load file Presentation presentation = new Presentation(); presentation.LoadFromFile("sample.pptx"); //comment author ICommentAuthor author = presentation.CommentAuthors.AddAuthor("E-iceblue", "comment:"); //add comment presentation.Slides[1].AddComment(author, "This part is pretty important. Please pay attention to it", new System.Drawing.PointF(42, 4), DateTime.Now); //save the document presentation.SaveToFile("PPTwithcomment.pptx", FileFormat.Pptx2010); System.Diagnostics.Process.Start("PPTwithcomment.pptx"); } } }
