   C#

using (FileStream fileStreamPath = new FileStream(Path.GetFullPath(@"Data/Input.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
   //Creates a new Word document.
   using (WordDocument document = new WordDocument(fileStreamPath, FormatType.Automatic))
   {
       // Find all text ranges in the document where the highlight color is Yellow
       List<Entity> textRanges = document.FindAllItemsByProperty(EntityType.TextRange, "CharacterFormat.HighlightColor.Name", "Yellow");
       // Check if any matching text ranges were found
       if (textRanges != null)
       {
           //Iterate text ranges
           foreach (Entity entity in textRanges)
           {
               WTextRange textRange = entity as WTextRange;
               // Clear the highlight color on this text range.
               textRange.CharacterFormat.HighlightColor = Color.Empty;
           }
       }
       //Create a file stream.
       using (FileStream outputFileStream = new FileStream(Path.GetFullPath(@"Output/Sample.docx"), FileMode.Create, FileAccess.ReadWrite))
       {
           //Save the Word document to the file stream.
