【概述】
Word中可插入文本框，在文本框中可添加文本、图片、表格等内容。本篇文章通过C#程序代码介绍如何来读取文本框中的文本、图片和表格等内容。附代码，有需要可作参考。
【程序环境】
程序中所需必要的程序集文件Spire.Doc.dll，及其他相关dll文件（见下文）。
用于测试的Word源文档如图：
【程序代码】
1.读取文本框中的文本
所需程序集:
【C#】
using Spire.Doc;using Spire.Doc.Documents;using Spire.Doc.Fields;using System;using System.IO;using System.Text;namespace ExtractText{class Program{static void Main(string[] args){//加载Word源文档Document doc = new Document();doc.LoadFromFile("test.docx");//获取文本框TextBox textbox = doc.TextBoxes[0];//创建StringBuilder类的对象StringBuilder sb = new StringBuilder();//遍历文本框中的对象，获取文本foreach (object obj in textbox.Body.ChildObjects){if (obj is Paragraph){String text = ((Paragraph)obj).Text;sb.AppendLine(text);}}//保存写入的txt文档到指定路径File.WriteAllText("ExtractedText.txt", sb.ToString());System.Diagnostics.Process.Start("ExtractedText.txt");}}}
【】
Imports Spire.DocImports Spire.Doc.DocumentsImports Spire.Doc.FieldsImports System.IOImports System.TextNamespace ExtractTextClass ProgramPrivate Shared Sub Main(args As String())'加载Word源文档Dim doc As New Document()doc.LoadFromFile("test.docx")'获取文本框Dim textbox As TextBox = doc.TextBoxes(0)'创建StringBuilder类的对象Dim sb As New StringBuilder()'遍历文本框中的对象，获取文本For Each obj As Object In textbox.Body.ChildObjectsIf TypeOf obj Is Paragraph ThenDim text As [String] = DirectCast(obj, Paragraph).Textsb.AppendLine(text)End IfNext'保存写入的txt文档到指定路径File.WriteAllText("ExtractedText.txt", sb.ToString())System.Diagnostics.Process.Start("ExtractedText.txt")End SubEnd ClassEnd Namespace
文本读取结果：
2.读取文本框中的图片
所需程序集:
【C#】
using Spire.Doc;using Spire.Doc.Documents;using Spire.Doc.Fields;using System;namespace ExtractImg{class Program{static void Main(string[] args){//加载Word源文档Document doc = new Document();doc.LoadFromFile("test.docx");//获取文本框TextBox textbox = doc.TextBoxes[0]; int index = 0 ;//遍历文本框中所有段落for (int i = 0 ; i < textbox.Body.Paragraphs.Count;i++){Paragraph paragraph = textbox.Body.Paragraphs[i];//遍历段落中的所有子对象for (int j = 0; j < paragraph.ChildObjects.Count; j++){object obj = paragraph.ChildObjects[j];//判定对象是否为图片if (obj is DocPicture){//获取图片DocPicture picture = (DocPicture) obj;String imageName = String.Format("Image-{0}.png", index);picture.Image.Save(imageName, System.Drawing.Imaging.ImageFormat.Png);index++;}}}}}}
【】
Imports Spire.DocImports Spire.Doc.DocumentsImports Spire.Doc.FieldsNamespace ExtractImgClass ProgramPrivate Shared Sub Main(args As String())'加载Word源文档Dim doc As New Document()doc.LoadFromFile("test.docx")'获取文本框Dim textbox As TextBox = doc.TextBoxes(0)Dim index As Integer = 0'遍历文本框中所有段落For i As Integer = 0 To textbox.Body.Paragraphs.Count - 1Dim paragraph As Paragraph = textbox.Body.Paragraphs(i)'遍历段落中的所有子对象For j As Integer = 0 To paragraph.ChildObjects.Count - 1Dim obj As Object = paragraph.ChildObjects(j)'判定对象是否为图片If TypeOf obj Is DocPicture Then'获取图片Dim picture As DocPicture = DirectCast(obj, DocPicture)Dim imageName As [String] = [String].Format("Image-{0}.png", index)picture.Image.Save(imageName, System.Drawing.Imaging.ImageFormat.Png)index += 1End IfNextNextEnd SubEnd ClassEnd Namespace
图片读取结果：
3.读取文本框中的表格
所需程序集:
【C#】
using Spire.Doc;using Spire.Doc.Documents;using Spire.Doc.Fields;using System.IO;using System.Text;namespace ExtractTable{class Program{static void Main(string[] args){//加载Word文档Document doc = new Document();doc.LoadFromFile("test.docx");//获取文本框TextBox textbox = doc.TextBoxes[0];//获取文本框中表格Table table = textbox.Body.Tables[0] as Table;StringBuilder sb = new StringBuilder();//遍历表格中的段落并提取文本foreach (TableRow row in table.Rows){foreach (TableCell cell in row.Cells){foreach (Paragraph paragraph in cell.Paragraphs){sb.AppendLine(paragraph.Text);}}}File.WriteAllText("ExtractedTable.txt", sb.ToString());}}}
【】
Imports Spire.DocImports Spire.Doc.DocumentsImports Spire.Doc.FieldsImports System.IOImports System.TextNamespace ExtractTableClass ProgramPrivate Shared Sub Main(args As String())'加载Word文档Dim doc As New Document()doc.LoadFromFile("test.docx")'获取文本框Dim textbox As TextBox = doc.TextBoxes(0)'获取文本框中表格Dim table As Table = TryCast(textbox.Body.Tables(0), Table)Dim sb As New StringBuilder()'遍历表格中的段落并提取文本For Each row As TableRow In table.RowsFor Each cell As TableCell In row.CellsFor Each paragraph As Paragraph In cell.Paragraphssb.AppendLine(paragraph.Text)NextNextNextFile.WriteAllText("ExtractedTable.txt", sb.ToString())End SubEnd ClassEnd Namespace
表格数据读取结果：
