當我們復制一個文件的某些內容到另一個文件時，我們經常會對Aspose.Words .NET 導入模式進行選擇。

ImportFormatMode.KeepSourceFormatting將保留在源文件中使用的原始格式的，而ImportFormatMode.UseDestinationStyles會使用在目標文檔中定義的格式。微軟Word也在復制內容到另一個文件時，提供了此選項選擇。

那么，Aspose.Words for .NET又是如何實現這兩種模式的選擇的呢？答案就在下面：

保留原格式的代碼如下：

C#

 // Load the documents to join.
Document dstDoc = new Document(gDataDir + "TestFile.Destination.doc");
Document srcDoc =  new Document(gDataDir + "TestFile.Source.doc");

// Keep the formatting from the source document when appending it to the destination document.
dstDoc.AppendDocument(srcDoc, ImportFormatMode.KeepSourceFormatting);

// Save the joined document to disk.
dstDoc.Save(gDataDir + "TestFile.KeepSourceFormatting Out.docx");
 

Visual Basic

 ' Load the documents to join.
Dim dstDoc As New Document(gDataDir & "TestFile.Destination.doc")
Dim srcDoc As New Document(gDataDir & "TestFile.Source.doc")

' Keep the formatting from the source document when appending it to the destination document.
dstDoc.AppendDocument(srcDoc, ImportFormatMode.KeepSourceFormatting)

' Save the joined document to disk.
dstDoc.Save(gDataDir & "TestFile.KeepSourceFormatting Out.docx")

 運行以上代碼后，目標文件不存在的格式也被復制過來了

而我們使用目標格式就不會有新的格式被創建，代碼如下：

C#

 // Load the documents to join.
Document dstDoc = new Document(gDataDir + "TestFile.Destination.doc");
Document srcDoc =  new Document(gDataDir + "TestFile.Source.doc");

// Append the source document using the styles of the destination document.
dstDoc.AppendDocument(srcDoc, ImportFormatMode.UseDestinationStyles);

// Save the joined document to disk.
dstDoc.Save(gDataDir + "TestFile.UseDestinationStyles Out.doc");
 

Visual Basic

 ' Load the documents to join.
Dim dstDoc As New Document(gDataDir & "TestFile.Destination.doc")
Dim srcDoc As New Document(gDataDir & "TestFile.Source.doc")

' Append the source document using the styles of the destination document.
dstDoc.AppendDocument(srcDoc, ImportFormatMode.UseDestinationStyles)

' Save the joined document to disk.
dstDoc.Save(gDataDir & "TestFile.UseDestinationStyles Out.doc")

 效果圖如下：
