日常开会或者作总结报告的时候咱们一般都会用到PowerPoint演示文稿,咱们能够在单个幻灯片或者所有幻灯片里面添加注释,这样观众能够从注释内容里面获取更多的相关信息。html
有些朋友不清楚如何在幻灯片里面添加注释,下面我跟你们分享一下如何在C#里面为幻灯片添加注释。ide
在这里我使用了一个免费控件——Free Spire.Presentation,有兴趣的朋友能够下载使用。 spa
须要添加的命名空间:component
using Spire.Presentation; using System.Drawing;
详细步骤和代码片断以下:orm
步骤1:新建一个Presentation对象,从系统里面加载Presentation文件。htm
Presentation presentation = new Presentation(); presentation.LoadFromFile("sample.pptx");
步骤2:调用CommentAuthorList.AddAuthor(author name, string initials) 方法来添加做者注释。对象
ICommentAuthor author = presentation.CommentAuthors.AddAuthor("E-iceblue", "comment:");
步骤3:调用Call presentation.Slides[].AddComment() 方法来给某一张特定幻灯片添加注解。注释的类包含不少信息,像添加注释的做者、添加注释的时间、添加注释的位置和注释的内容。blog
presentation.Slides[1].AddComment(author, "This part is pretty important. Please pay attention to it", new System.Drawing.PointF(42, 4), DateTime.Now);
步骤4:保存并从新打开Presentation演示文稿。get
presentation.SaveToFile("PPTwithcomment.pptx", FileFormat.Pptx2010); System.Diagnostics.Process.Start("PPTwithcomment.pptx");
效果图:string
所有代码:
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"); } } }
