IMPORTANT

Take into account the following when you call this method:

  • The events fired by this method's call may occur in a different thread than the target operation.

  • The operation is not thread safe (documents should not be accessed simultaneously by different threads). Wait until the operation is completed before working with the document, i.e., use the await operator.

The code sample below asynchronously exports a document to the PDF format:

private async void ConvertDocx2Pdf()
{
  using (RichEditDocumentServer wordProcessor = new RichEditDocumentServer())
    {
        try
        {
            await wordProcessor.LoadDocumentAsync("Document.docx");

            await wordProcessor.ExportToPdfAsync(new FileStream("Documents\\Result.pdf",
    FileMode.Create, FileAccess.ReadWrite));
        }
        catch (OperationCanceledException)
        {
            // Your code to handle cancellation
        }
    }
}
