Example

How to: Proofread a Word Document

The following code snippet proofreads an entire document. Code to proofread only the second paragraph is included as commented code.

C#

using DevExpress.AIIntegration.Docs;
using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.API.Native;
using System.Diagnostics;

var docProcessingService = defaultAIExtensionsContainer.CreateAIDocProcessingService();

using (var wordProcessor = new RichEditDocumentServer())
{
    // Load source document (ensure file exists in relative Documents folder)
    wordProcessor.LoadDocument("Documents/FirstLookShortened.docx");

    // Proofread entire document (culture en-US)
    await docProcessingService.ProofreadAsync(wordProcessor, new System.Globalization.CultureInfo("en-US"));

    // Proofread a single paragraph
    // Paragraph paragraph = wordProcessor.Document.Paragraphs[1];
    // await docProcessingService.ProofreadAsync(paragraph.Range, new System.Globalization.CultureInfo("en-US"));

    // Prepare output directory & file path
    string targetDir = @"C:\Test Documents";
    Directory.CreateDirectory(targetDir); // Safe if already exists
    string outputPath = Path.Combine(targetDir, "Proofread.docx");

    // Save the proofread document
    using (FileStream outputStream = new FileStream(outputPath, FileMode.Create, FileAccess.Write))
    {
        wordProcessor.SaveDocument(outputStream, DocumentFormat.OpenXml);
    }
}
