How to determine the page number of a particular text within a Word document?

Syncfusion® Essential® DocIO is a .NET Word library used to create, read, and edit Word documents programmatically without Microsoft Word or Interop dependencies. Using this library, you can determine the page number of a particular text within a Word document.

Steps to determine the page number of a particular text within a Word document programmatically:

1. Create a new C# Windows Forms application project.

2. Install the Syncfusion.DocToPDFConverter.WinForms and Syncfusion.PdfViewer.Windows NuGet packages as a reference to your .NET Framework applications from NuGet.org.

3. Add a new button in Form1.Designer.cs as follows.

private System.Windows.Forms.Button button1;
 
private void InitializeComponent()
{
    this.button1 = new System.Windows.Forms.Button();
    this.SuspendLayout();
    // 
    // button1
    // 
    this.button1.Location = new System.Drawing.Point(265, 167);
    this.button1.Name = "Submit";
    this.button1.Size = new System.Drawing.Size(201, 83);
    this.button1.TabIndex = 0;
    this.button1.Text = "Submit";
    this.button1.UseVisualStyleBackColor = true;
    this.button1.Click += new System.EventHandler(this.button1_Click);
    // 
    // Form1
    // 
    this.AutoScaleDimensions = new System.Drawing.SizeF(9F, 20F);
    this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
    this.ClientSize = new System.Drawing.Size(800, 450);
    this.Controls.Add(this.button1);
    this.Name = "Form1";
    this.Text = "Form1";
    this.ResumeLayout(false);
}

4. Include the following namespace in the Form1.cs file.

   using Syncfusion.DocIO;
   using Syncfusion.DocIO.DLS;
   using Syncfusion.DocToPDFConverter;
   using Syncfusion.Pdf;
   using Syncfusion.Windows.Forms.PdfViewer;
   

5. Use the following code example to determine the page number of a particular text within a Word document.

   private void button1_Click(object sender, EventArgs e)
   {
        WordDocument wordDocument = new WordDocument(@"source.docx");
        DocToPDFConverter converter = new DocToPDFConverter();
        PdfDocument pdfDocument = converter.ConvertToPDF(wordDocument);
        MemoryStream stream = new MemoryStream();
        pdfDocument.Save(stream);
        pdfDocument.Close(true);
        wordDocument.Close();
        converter.Dispose();
        stream.Position = 0;
    
        FileStream fileStream = new FileStream("Output.pdf", FileMode.Create);
        stream.CopyTo(fileStream);
        fileStream.Close();
    
        PdfViewerControl documentViewer = new PdfViewerControl();
        //Load the PDF document
        documentViewer.Load(stream);
    
        //Get the occurrences of the target text and location.
        Dictionary<int, List<RectangleF>> textSearch = new Dictionary<int, List<RectangleF>>();
        bool IsMatchFound = documentViewer.FindText("Revision History", out textSearch);
        List<int> pageNumbers = null;
        if (IsMatchFound)
        {
            pageNumbers = GetPageNumebers(textSearch);
        }
        documentViewer.Dispose();
   }
   

6. Helper method to get the page number of given text.

   /// <summary>
   /// Get the page number of give text
   /// </summary>
   /// <param name="textSearch"></param>
   /// <returns></returns>
   private List<int> GetPageNumebers(Dictionary<int, List<RectangleF>> textSearch)
   {
       List<int> list = new List<int>();
       int i = 0;
       foreach (List<RectangleF> rectangles in textSearch.Values)
       {
           if (rectangles.Count != 0)
           {
               list.Add(textSearch.FirstOrDefault(x => x.Value == rectangles).Key + 1);
               i++;
           }
       }
       return list;
   }
