本文将介绍通过使用Spire.Doc for .NET根据段落标题样式名称来读取Word中相应段落的方法。

//创建Document对象，并加载测试文档
Document doc = new Document();
doc.LoadFromFile("sample.doc");

//实例化StringBuilder对象
StringBuilder sb = new StringBuilder();

//遍历文档
foreach (Section section in doc.Sections)
{
    foreach (Paragraph paragraph in section.Paragraphs)
    {
               //判断段落标题名称
                    if (paragraph.StyleName == "Heading1")
                    {
                        sb.AppendLine(paragraph.Text);
                    }
                    if (paragraph.StyleName == "Heading2")
                    {
                        sb.AppendLine(paragraph.Text);
                    }
                    if (paragraph.StyleName == "Heading3")
                    {
                        sb.AppendLine(paragraph.Text);
                    }
                    if (paragraph.StyleName == "Heading4")
                    {
                        sb.AppendLine(paragraph.Text);
                    }
    }
}

//将符合标题名称的段落写入.txt文档
File.WriteAllText("Extract.txt", sb.ToString());

'创建Document对象，并加载测试文档
Dim doc As Document = New Document
doc.LoadFromFile("sample.doc")
'实例化StringBuilder对象
Dim sb As StringBuilder = New StringBuilder
'遍历文档
For Each section As Section In doc.Sections
    For Each paragraph As Paragraph In section.Paragraphs
        '判断段落标题名称
        If (paragraph.StyleName = "Heading1") Then
            sb.AppendLine(paragraph.Text)
        End If
        
        If (paragraph.StyleName = "Heading2") Then
            sb.AppendLine(paragraph.Text)
        End If
        
        If (paragraph.StyleName = "Heading3") Then
            sb.AppendLine(paragraph.Text)
        End If
        
        If (paragraph.StyleName = "Heading4") Then
            sb.AppendLine(paragraph.Text)
        End If
        
    Next
Next
'将符合标题名称的段落写入.txt文档
File.WriteAllText("Extract.txt", sb.ToString)

读取结果：
