+# Replace bookmark content with Word document part using C#
+
+The Syncfusion [.NET Word Library](https://www.syncfusion.com/document-processing/word-framework/net/word-library) (DocIO) enables you to create, read, and edit Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can **replace bookmark content in a Word document with another Word document content** using C#.
+
+## Steps to replace bookmark content programmatically
+
+Step 1: Create a new .NET Core console application project.
+
+Step 2: Install the [Syncfusion.DocIO.Net.Core](https://www.nuget.org/packages/Syncfusion.DocIO.Net.Core) NuGet package as a reference to your project from [NuGet.org](https://www.nuget.org/).
+
+Step 3: Include the following namespaces in the Program.cs file.
+
+```csharp
+using Syncfusion.DocIO; 
+using Syncfusion.DocIO.DLS;
+using System.IO;
+```
+
+Step 4: Add the following code snippet in Program.cs file to replace bookmark content with another Word document part.
+
+```csharp
+using (FileStream fileStreamPath = new FileStream(Path.GetFullPath(@"Data/Template.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
+{
+    //Opens an existing Word document.
+    using (WordDocument templateDocument = new WordDocument(fileStreamPath, FormatType.Automatic))
+    {
+        //Creates the bookmark navigator instance to access the bookmark.
+        BookmarksNavigator bookmarkNavigator = new BookmarksNavigator(templateDocument);
+        //Moves the virtual cursor to the location before the end of the bookmark "Northwind".
+        bookmarkNavigator.MoveToBookmark("Northwind");
+        //Gets the bookmark content as WordDocumentPart.
+        WordDocumentPart wordDocumentPart = bookmarkNavigator.GetContent();
+        //Loads the Word document with bookmark NorthwindDB.
+        using (FileStream fileStream = new FileStream(Path.GetFullPath(@"Data/Bookmarks.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
+        {
+            using (WordDocument document = new WordDocument(fileStream, FormatType.Docx))
+            {
+                //Creates the bookmark navigator instance to access the bookmark.
+                bookmarkNavigator = new BookmarksNavigator(document);
+                //Moves the virtual cursor to the location before the end of the bookmark "NorthwindDB".
+                bookmarkNavigator.MoveToBookmark("NorthwindDB");
+                //Replaces the bookmark content with word body part.
+                bookmarkNavigator.ReplaceContent(wordDocumentPart);
+                //Close the WordDocumentPart instance.
+                wordDocumentPart.Close();
+                //Creates file stream.
+                using (FileStream outputFileStream = new FileStream(Path.GetFullPath(@"Output/Output.docx"), FileMode.Create, FileAccess.ReadWrite))
+                {
+                    //Saves the Word document to file stream.
+                    document.Save(outputFileStream, FormatType.Docx);
+                }
+            }
+        }
+    }
+}
+```
