How to Apply a Left Indent to the Imported Content in Core DocIO?

Syncfusion Essential DocIO is a .NET Word Library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can apply a left indent to the imported content after the list paragraph in a Word document using C#.

Steps to apply a left indent to the imported content after the list paragraph in Word document:

1. Create a new .NET Core console application project.
2. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your project from NuGet.org.
   
   

3. Include the following namespaces in Program.cs file
   C#

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;

4. Use the following code example to import content into a main Word document and apply a left indent.
   C#

// Open the existing main document from a file stream.
using (FileStream destinationStream = new FileStream(Path.GetFullPath(@"Data/DestinationDocument.docx"), FileMode.Open))
{
   // Load the main Word document.
   using (WordDocument destinationDocument = new WordDocument(destinationStream, FormatType.Docx))
   {
       // Open the existing source document from a file stream.
       using (FileStream sourceStream = new FileStream(Path.GetFullPath(@"Data/SourceDocument.docx"), FileMode.Open))
       {
           // Load the source Word document.
           using (WordDocument sourceDocument = new WordDocument(sourceStream, FormatType.Docx))
           {
               // Set the first section break in the source document to "NoBreak" for seamless merging.
               sourceDocument.Sections[0].BreakCode = SectionBreakCode.NoBreak;

               // Get the index of the last section in the destination document.
               int secIndex = destinationDocument.ChildEntities.IndexOf(destinationDocument.LastSection);

               // Get the index of the last paragraph in the last section of the destination document.
               int paraIndex = destinationDocument.LastSection.Body.ChildEntities.IndexOf(destinationDocument.LastParagraph);

               // Get the style and formatting of the last paragraph for reference.
               WParagraph lastPara = destinationDocument.LastParagraph;

               // Import content from the source document into the destination document, using destination styles.
               destinationDocument.ImportContent(sourceDocument, ImportOptions.UseDestinationStyles);

               // Modify the paragraph style for the newly added contents by applying left indentation.
               AddLeftIndentation(destinationDocument, secIndex, paraIndex + 1, lastPara.ParagraphFormat.LeftIndent);

               // Save the updated destination document to a new file.
               using (FileStream outputStream = new FileStream(Path.GetFullPath(@"Output/Output.docx"), FileMode.Create, FileAccess.Write))
               {
                   destinationDocument.Save(outputStream, FormatType.Docx);
               }
           }
       }
   }
}

5. Use the following helper method to apply a specified left indent to all paragraphs and tables after imported sections of a Word document.
   C#

/// <summary>
/// Applies left indentation to paragraphs and tables in a specified section and paragraph range of a Word document.
/// </summary>
void AddLeftIndentation(WordDocument document, int secIndex, int paraIndex, float leftIndent)
{
   // Iterate through the sections added from the source document, starting from secIndex.
   for (int i = secIndex; i < document.ChildEntities.IndexOf(document.LastSection) + 1; i++)
   {
       // Iterate through the child entities (paragraphs/tables) added from the source document.
       for (int j = paraIndex; j < document.Sections[i].Body.ChildEntities.Count; j++)
       {
           // If the child entity is a paragraph, apply the left indent from the last paragraph.
           if (document.Sections[i].Body.ChildEntities[j] is WParagraph)
           {
               WParagraph para = document.Sections[i].Body.ChildEntities[j] as WParagraph;
               // Set the left indentation for the paragraph
               para.ParagraphFormat.LeftIndent = leftIndent;
           }
           // If the child entity is a table, apply the same left indent to the table.
           else if (document.Sections[i].Body.ChildEntities[j] is WTable)
           {
               WTable table = document.Sections[i].Body.ChildEntities[j] as WTable;
               // Set the left indentation for the table.
               table.TableFormat.LeftIndent = leftIndent;
           }
       }
       // Reset the paragraph index for the next section to start from the beginning.
       paraIndex = 0;
   }
}
