C#/VB.NET 操作Word批注（二）——如何插入图片、读取、回复Word批注内容

序

在前面的文章C# 如何插入、修改、删除Word批注一文中介绍了如何操作Word批注的一些方法，在本篇文章中将继续介绍操作Word批注的方法。分以下三种情况来介绍：

1. 插入图片到Word批注
2. 读取Word批注
3. 回复Word批注

所需工具

• Spire.Doc for .NET 6.3（社区版）
• Visual Stuido

示例代码

1. 插入图片到Word批注

【C#】

using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System.Drawing;

namespace InsertImgToComment_Doc
{
    class Program
    {
        static void Main(string[] args)
        {
            //实例化Document类，加载文档
            Document doc = new Document();
            doc.LoadFromFile("testfile.docx");

            //获取需要添加批注的段落
            Paragraph paragraph = doc.Sections[0].Paragraphs[2];

            //添加文本批注内容、批注作者
            Comment comment = paragraph.AppendComment("探索黑科技，小米为发烧而生!");
            comment.Format.Author = "Administor";

            //实例化DocPicture类，加载图片
            DocPicture docPicture = new DocPicture(doc);
            Image img = Image.FromFile("mi.png");
            docPicture.LoadImage(img);
            //插入图片到批注
            comment.Body.AddParagraph().ChildObjects.Add(docPicture);

            //保存文件并打开文档
            doc.SaveToFile("result.docx", FileFormat.Docx2013);
            System.Diagnostics.Process.Start("result.docx");
        }
    }
}

【VB.NET】

Imports Spire.Doc
Imports Spire.Doc.Documents
Imports Spire.Doc.Fields
Imports System.Drawing

Namespace InsertImgToComment_Doc
    Class Program
        Private Shared Sub Main(ByVal args As String())
            Dim doc As Document = New Document()
            doc.LoadFromFile("testfile.docx")
            Dim paragraph As Paragraph = doc.Sections(0).Paragraphs(2)
            Dim comment As Comment = paragraph.AppendComment("探索黑科技，小米为发烧而生!")
            comment.Format.Author = "Administor"
            Dim docPicture As DocPicture = New DocPicture(doc)
            Dim img As Image = Image.FromFile("mi.png")
            docPicture.LoadImage(img)
            comment.Body.AddParagraph().ChildObjects.Add(docPicture)
            doc.SaveToFile("result.docx", FileFormat.Docx2013)
            System.Diagnostics.Process.Start("result.docx")
        End Sub
    End Class
End Namespace

2.读取Word批注内容

【C#】

using System.Text;
using System.IO;
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;

namespace ExtractComments
{
    class Program
    {
        static void Main(string[] args)
        {
            //创建实例，加载文档
            Document doc = new Document();
            doc.LoadFromFile("test.docx");

            //实例化StringBuilder类
            StringBuilder SB = new StringBuilder();
            //遍历所有word批注，将批注内容写入Txt文档
            foreach (Comment comment in doc.Comments)
            {
                foreach (Paragraph p in comment.Body.Paragraphs)
                {
                    SB.AppendLine(p.Text);
                }
            }
            File.WriteAllText("CommentExtraction.txt", SB.ToString());
            System.Diagnostics.Process.Start("CommentExtraction.txt");
        }
    }
}

【VB.NET】

Imports System.Text
Imports System.IO
Imports Spire.Doc
Imports Spire.Doc.Documents
Imports Spire.Doc.Fields

Namespace ExtractComments
    Class Program
        Private Shared Sub Main(ByVal args As String())
            Dim doc As Document = New Document()
            doc.LoadFromFile("test.docx")
            Dim SB As StringBuilder = New StringBuilder()

            For Each comment As Comment In doc.Comments

                For Each p As Paragraph In comment.Body.Paragraphs
                    SB.AppendLine(p.Text)
                Next
            Next

            File.WriteAllText("CommentExtraction.txt", SB.ToString())
            System.Diagnostics.Process.Start("CommentExtraction.txt")
        End Sub
    End Class
End Namespace

读取结果:

3.回复Word批注

【C#】

using Spire.Doc;
using Spire.Doc.Fields;

namespace ReplyComment_Doc
{
    class Program
    {
        static void Main(string[] args)
        {
            //实例化Document类，加载文件
            Document doc = new Document();
            doc.LoadFromFile("test.docx");

            //获取第一个批注
            Comment comment = doc.Comments[0];

            //实例化Comment类，添加批注回复作者以及回复内容
            Comment replyComment = new Comment(doc);
            replyComment.Format.Author = "Adam";
            replyComment.Body.AddParagraph().AppendText("这条批注内容请再丰富一下，内容有些单调");
            comment.ReplyToComment(replyComment);

            //保存文件并打开
            doc.SaveToFile("ReplyToComment.docx", FileFormat.Docx2013);
            System.Diagnostics.Process.Start("ReplyToComment.docx");
        }
    }
}

【VB.NET】

Imports Spire.Doc
Imports Spire.Doc.Fields

Namespace ReplyComment_Doc
    Class Program
        Private Shared Sub Main(ByVal args As String())
            Dim doc As Document = New Document()
            doc.LoadFromFile("test.docx")
            Dim comment As Comment = doc.Comments(0)
            Dim replyComment As Comment = New Comment(doc)
            replyComment.Format.Author = "Adam"
            replyComment.Body.AddParagraph().AppendText("这条批注内容请再丰富一下，内容有些单调")
            comment.ReplyToComment(replyComment)
            doc.SaveToFile("ReplyToComment.docx", FileFormat.Docx2013)
            System.Diagnostics.Process.Start("ReplyToComment.docx")
        End Sub
    End Class
End Namespace

测试结果：

需要注意的是，在回复Word批注这个功能上，免费版的Spire.Doc暂不支持，须使用商业版。
以上为本次关于操作Word批注的全部内容。
