using Syncfusion.Pdf;
Step 4: Add a new button in Form1.Designer.cs to create Word file as follows.
private Button btnCreate;
private Label label;
private void InitializeComponent()
{
label = new Label();
btnCreate = new Button();
//Label
label.Location = new System.Drawing.Point(0, 40);
label.Size = new System.Drawing.Size(426, 35);
label.Text = "Click the button to Convert Word document to PDF generated by Essential DocIO. Please note that Microsoft Word Viewer or Microsoft Word is required to view the resultant Word document";
label.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
//Button
btnCreate.Location = new System.Drawing.Point(180, 110);
btnCreate.Size = new System.Drawing.Size(85, 36);
btnCreate.Text = "Convert Word document to PDF";
btnCreate.Click += new EventHandler(btnConvert_Click);
//Create Word
ClientSize = new System.Drawing.Size(450, 150);
Controls.Add(label);
Controls.Add(btnCreate);
Text = "Convert Word document to PDF";
}

{
//Instantiation of DocToPDFConverter for Word to PDF conversion
using (DocToPDFConverter converter = new DocToPDFConverter())
{
//Converts Word document into PDF document
using (PdfDocument pdfDocument = converter.ConvertToPDF(document))
{
//Saves the PDF document
pdfDocument.Save(Path.GetFullPath(@"../../Sample.pdf"));
}
};
}
