向使用OpenXML创建的电子表格文档中的单元格添加注释

Question

I am creating an xlsx file using openXML. I want to add comments to some row cells. Is there any way to add comments to the cell. Or should I use Microsoft.Office.Interop to add comments to the excel cells ?

Answer 1

I used the Open XML SDK Productivity Tool for Microsoft Office which lets you load an Excel or Word file and then emits the C# code to produce that exact file.

Then I created a file with a comment. First I tried with two comments but the amount of code it generates makes it hard to tell what's what.

The result is not pretty to look at. You could reduce a lot of it and probably eliminate some. But it's a way to find out what's going on under the hood.

You can also skip all of this and just use EPPlus , which after looking at what comes next you can imagine why someone felt the need to make this easier.

The key steps are:

• Create a new Comments
• Create a new CommentsList (?!!!)
• Create a new Comment which has a Reference property indicating which cell it belongs to
• Create a new CommentText
• Create a new Run
• Append the Run to the CommentText
• Append the CommentText to the Comment
• Append the Comment to the CommentsList
• Append the CommentsList to the Comments

• Set the WorksheetCommentsPart.Comments property to the Comments .

   private void GenerateWorksheetCommentsPart1Content(WorksheetCommentsPart worksheetCommentsPart1) { Comments comments1 = new Comments(){ MCAttributes = new MarkupCompatibilityAttributes(){ Ignorable = "xr" } }; comments1.AddNamespaceDeclaration("mc", "http://schemas.openxmlformats.org/markup-compatibility/2006"); comments1.AddNamespaceDeclaration("xr", "http://schemas.microsoft.com/office/spreadsheetml/2014/revision"); Authors authors1 = new Authors(); Author author1 = new Author(); author1.Text = "Hannen, Scott"; authors1.Append(author1); CommentList commentList1 = new CommentList(); Comment comment1 = new Comment(){ Reference = "B3", AuthorId = (UInt32Value)0U, ShapeId = (UInt32Value)0U }; comment1.SetAttribute(new OpenXmlAttribute("xr", "uid", "http://schemas.microsoft.com/office/spreadsheetml/2014/revision", "{811649EF-4CB5-4311-BE14-228133003BE4}")); CommentText commentText1 = new CommentText(); Run run1 = new Run(); RunProperties runProperties1 = new RunProperties(); FontSize fontSize3 = new FontSize(){ Val = 9D }; Color color3 = new Color(){ Indexed = (UInt32Value)81U }; RunFont runFont1 = new RunFont(){ Val = "Tahoma" }; RunPropertyCharSet runPropertyCharSet1 = new RunPropertyCharSet(){ Val = 1 }; runProperties1.Append(fontSize3); runProperties1.Append(color3); runProperties1.Append(runFont1); runProperties1.Append(runPropertyCharSet1); Text text1 = new Text(){ Space = SpaceProcessingModeValues.Preserve }; text1.Text = "This is my comment!\\nThis is line 2!\\n"; run1.Append(runProperties1); run1.Append(text1); commentText1.Append(run1); comment1.Append(commentText1); commentList1.Append(comment1); comments1.Append(authors1); comments1.Append(commentList1); worksheetCommentsPart1.Comments = comments1; }
