How to Create Word Document Using C#

This article shows how to create a Word document using C# and Office 2013.

Step 1: Create a simple Windows application and place a button control in it.
 

Step 2: Double-click the button control and go to the code widow.

Step 3: Add a reference for "Microsoft.Office.Interop.Word" as shown in the following image.
 

Step 4: Copy and paste the following code to generate the Word document.
 

The code is self-explanatory and the required comments are added wherever they are required.

 

         private void button1_Click(object sender, EventArgs e)
        {
            CreateDocument();
        }

      //Create document method
        private void CreateDocument()
        {
            try
            {
                //Create an instance for word app
                Microsoft.Office.Interop.Word.Application winword = new Microsoft.Office.Interop.Word.Application();

                //Set animation status for word application
                winword.ShowAnimation = false;

                //Set status for word application is to be visible or not.
                winword.Visible = false;
                
                //Create a missing variable for missing value
                object missing = System.Reflection.Missing.Value;

                //Create a new document
                Microsoft.Office.Interop.Word.Document document = winword.Documents.Add(ref missing, ref missing, ref missing, ref missing);
                
                //Add header into the document
                foreach (Microsoft.Office.Interop.Word.Section section in document.Sections)
                {

                    //Get the header range and add the header details.
                    Microsoft.Office.Interop.Word.Range headerRange = section.Headers[Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range;
                    headerRange.Fields.Add(headerRange, Microsoft.Office.Interop.Word.WdFieldType.wdFieldPage);
                    headerRange.ParagraphFormat.Alignment = Microsoft.Office.Interop.Word.WdParagraphAlignment.wdAlignParagraphCenter;
                    headerRange.Font.ColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdBlue;
                    headerRange.Font.Size = 10;
                    headerRange.Text = "Header text goes here";
                }

                //Add the footers into the document
                foreach (Microsoft.Office.Interop.Word.Section wordSection in document.Sections)
                {

                    //Get the footer range and add the footer details.
                    Microsoft.Office.Interop.Word.Range footerRange = wordSection.Footers[Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range;
                    footerRange.Font.ColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdDarkRed;
                    footerRange.Font.Size =10;
                    footerRange.ParagraphFormat.Alignment = Microsoft.Office.Interop.Word.WdParagraphAlignment.wdAlignParagraphCenter;
                    footerRange.Text = "Footer text goes here";
                }

                //adding text to document
                document.Content.SetRange(0, 0);
                document.Content.Text = "This is test document "+ Environment.NewLine;
                
                //Add paragraph with Heading 1 style
                Microsoft.Office.Interop.Word.Paragraph para1 = document.Content.Paragraphs.Add(ref missing);                
                object styleHeading1 = "Heading 1";
                para1.Range.set_Style(ref styleHeading1);                
                para1.Range.Text = "Para 1 text";
                para1.Range.InsertParagraphAfter();

                //Add paragraph with Heading 2 style
                Microsoft.Office.Interop.Word.Paragraph para2 = document.Content.Paragraphs.Add(ref missing);
                object styleHeading2 = "Heading 2";
                para2.Range.set_Style(ref styleHeading2);
                para2.Range.Text = "Para 2 text";
                para2.Range.InsertParagraphAfter();

                //Create a 5X5 table and insert some dummy record
                Table firstTable = document.Tables.Add(para1.Range, 5, 5, ref missing, ref missing);
                
                firstTable.Borders.Enable = 1;
                foreach (Row row in firstTable.Rows)
                {
                    foreach (Cell cell in row.Cells)
                    {
                        //Header row
                        if (cell.RowIndex == 1)
                        {
                            cell.Range.Text = "Column " + cell.ColumnIndex.ToString();
                            cell.Range.Font.Bold = 1;
                            //other format properties goes here
                            cell.Range.Font.Name = "verdana";
                            cell.Range.Font.Size = 10;
                            //cell.Range.Font.ColorIndex = WdColorIndex.wdGray25;                            
                            cell.Shading.BackgroundPatternColor = WdColor.wdColorGray25;
                            //Center alignment for the Header cells
                            cell.VerticalAlignment = WdCellVerticalAlignment.wdCellAlignVerticalCenter;
                            cell.Range.ParagraphFormat.Alignment = WdParagraphAlignment.wdAlignParagraphCenter;
                            
                        }
                        //Data row
                        else
                        {
                            cell.Range.Text = (cell.RowIndex - 2 + cell.ColumnIndex).ToString();
                        }
                    }
                }
                
                //Save the document
                object filename = @"c:\temp1.docx";
                document.SaveAs2(ref filename);
                document.Close(ref missing, ref missing, ref missing);
                document = null;
                winword.Quit(ref missing, ref missing, ref missing);
                winword = null;
                MessageBox.Show("Document created successfully !");
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

Step 5: Once the code is executed successfully, the document output will be:
