- Create a new C# console application project.
- Install the Syncfusion.DocIO.WinForms NuGet package as a reference to your .NET Framework applications from NuGet.org.
- Include the following namespaces in the Program.cs file.
C#
using Syncfusion.DocIO.DLS; using System.Drawing;
VB
Imports Syncfusion.DocIO.DLS Imports System.Drawing
- Use the following code snippet to insert content into a Word document with text and images.
C#
// Creates a new Word document.
using (WordDocument document = new WordDocument())
{
// Adds a new section to the document.
IWSection section = document.AddSection();
// Sets the margin of the section.
section.PageSetup.Margins.All = 72;
// Adds a new paragraph to the section.
IWParagraph paragraph = section.AddParagraph();
paragraph.ParagraphFormat.HorizontalAlignment = Syncfusion.DocIO.DLS.HorizontalAlignment.Center;
paragraph.ApplyStyle(BuiltinStyle.Heading1);
// Adds new text to the paragraph.
WTextRange textRange = paragraph.AppendText("Adventure Works Cycles") as WTextRange;
textRange.CharacterFormat.FontSize = 18f;
textRange.CharacterFormat.FontName = "Calibri";
// Adds a new paragraph to the section.
paragraph = section.AddParagraph();
paragraph.ParagraphFormat.FirstLineIndent = 36;
paragraph.BreakCharacterFormat.FontSize = 12f;
// Adds new text to the paragraph.
textRange = paragraph.AppendText("Adventure Works Cycles, the fictitious company on which the AdventureWorks sample databases are based, is a large, multinational manufacturing company. The company manufactures and sells metal and composite bicycles to North American, European, and Asian commercial markets. While its base operation is in Bothell, Washington with 290 employees, several regional sales teams are located throughout their market base.") as WTextRange;
textRange.CharacterFormat.FontSize = 12f;
// Adds a new paragraph to the section.
paragraph = section.AddParagraph();
paragraph.ApplyStyle(BuiltinStyle.Heading1);
paragraph.ParagraphFormat.HorizontalAlignment = Syncfusion.DocIO.DLS.HorizontalAlignment.Center;
// Adds new text to the paragraph.
textRange = paragraph.AppendText("Product Overview") as WTextRange;
textRange.CharacterFormat.FontSize = 16f;
textRange.CharacterFormat.FontName = "Calibri";
// Adds a new paragraph to the section.
paragraph = section.AddParagraph();
paragraph.ParagraphFormat.HorizontalAlignment = Syncfusion.DocIO.DLS.HorizontalAlignment.Center;
paragraph.ParagraphFormat.BeforeSpacing = 12f;
// Appends a picture to the paragraph.
WPicture picture = (WPicture)paragraph.AppendPicture(Image.FromFile(@"..\..\Images\Mountain-200.png"));
// Adds a new paragraph to the section.
paragraph = section.AddParagraph();
paragraph.ParagraphFormat.HorizontalAlignment = Syncfusion.DocIO.DLS.HorizontalAlignment.Center;
paragraph.ParagraphFormat.BeforeSpacing = 12f;
// Appends a picture to the paragraph.
picture = (WPicture)paragraph.AppendPicture(Image.FromFile(@"..\..\Images\Road-550-W.jpg"));
// Saves the Word document.
document.Save("Result.docx");
