复制 Word 段落时，用户可以选择仅复制文本或复制段落的所有元素，例如格式、图像、超链接等。本指南中的解决方案介绍了如何在 C# 中将 Word 段落（文本和格式）从一个文档复制到另一个文档和VB.NET 通过 Spire.Doc for .NET。

Spire.Doc for.NET 最新下载

Spire.Doc for .NET是一个独立的 .NET Word 组件，它提供了一个方法Paragraph.Clone()来允许用户复制段落。以下屏幕截图显示了复制后的结果。

下载并安装 Spire.Doc for .NET并按照步骤复制 Word 段落。首先，从指定的文档初始化一个文档实例 doc1 和一个新的文档实例 doc2。其次，初始化两个Paragraph实例p1和p2，它们是doc1的标题和第一段。第三，实例化一个新的 Section 实例和两个 Paragraph 实例。将调用 Paragraph.Clone() 后的结果分配为这两个实例的值。然后，使用参数paragraph 调用Section.Paragraph.Add 方法将复制的段落添加到新文档中。代码如下：

[C＃]

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

namespace CopyParagraph
{
class Program
{
static void Main(string[] args)
{
//Load doc1
Document doc1 = new Document();
doc1.LoadFromFile(@"E:\Work\Document\A GOOD MAN IS HARD TO FIND.docx");

//Create New doc2
Document doc2 = new Document();

//Get Paragraph 1(the Title) and Paragraph 2(body) in Doc1
Section s = doc1.Sections[0];
Paragraph p1 = s.Paragraphs[0];
Paragraph p2 = s.Paragraphs[1];

//Copy p1 and p2 to doc2
Section s2 = doc2.AddSection();
Paragraph NewPara1 = (Paragraph)p1.Clone();
s2.Paragraphs.Add(NewPara1);
Paragraph NewPara2 = (Paragraph)p2.Clone();
s2.Paragraphs.Add(NewPara2);

//Add Watermark
PictureWatermark WM = new PictureWatermark();
WM.Picture = Image.FromFile(@"E:\Work\Document\Rose.jpg");
doc2.Watermark = WM;

//Save and Launch
doc2.SaveToFile("copy.docx", FileFormat.Docx2010);
System.Diagnostics.Process.Start("copy.docx");
}
}
}

[VB.NET]

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

Namespace CopyParagraph
Friend Class Program
Shared Sub Main(ByVal args() As String)
'Load doc1
Dim doc1 As New Document()
doc1.LoadFromFile("E:\Work\Document\A GOOD MAN IS HARD TO FIND.docx")

'Create New doc2
Dim doc2 As New Document()

'Get Paragraph 1(the Title) and Paragraph 2(body) in Doc1
Dim s As Section = doc1.Sections(0)
Dim p1 As Paragraph = s.Paragraphs(0)
Dim p2 As Paragraph = s.Paragraphs(1)

'Copy p1 and p2 to doc2
Dim s2 As Section = doc2.AddSection()
Dim NewPara1 As Paragraph = CType(p1.Clone(), Paragraph)
s2.Paragraphs.Add(NewPara1)
Dim NewPara2 As Paragraph = CType(p2.Clone(), Paragraph)
s2.Paragraphs.Add(NewPara2)

'Add Watermark
Dim WM As New PictureWatermark()
WM.Picture = Image.FromFile("E:\Work\Document\Rose.jpg")
doc2.Watermark = WM

'Save and Launch
doc2.SaveToFile("copy.docx", FileFormat.Docx2010)
System.Diagnostics.Process.Start("copy.docx")
End Sub
End Class
End Namespace

注意：因为paragraph.Clone() 的类型是DocumentObject，所以在新建Word 文档doc2 中初始化段落实例时将其类型转换为Paragraph。

Spire.Doc 作为专业的 Word 组件，在无需 Word 自动化和任何第三方工具的情况下，在 .NET、WPF、Silverlight 中快速生成、加载、编写、修改和保存 Word 文档非常强大。
