How to Create Word Document in C#

By Tan Lee Published on Jan 17, 2025 386

Creating a Word document programmatically in C# can be achieved using the Microsoft.Office.Interop.Word library.

This library allows you to interact with Microsoft Word, enabling you to create, modify, and save Word documents directly from your C# application.

Prerequisites

Before diving into the code, ensure the following prerequisites are met:

Microsoft Office Installation: MS Office must be installed on your machine.
Project Setup: Create a Console or Windows application in Visual Studio.
Add Reference: Add a reference to the Microsoft.Office.Interop.Word library.
You can find this DLL at:
C:\Windows\assembly\GAC_MSIL\Microsoft.Office.Interop.Word\15.0.0.0__71e9bce111e9429c\Microsoft.Office.Interop.Word.dll.

Below is a sample implementation of creating a Word document with a header, content, and a table.

For example, word c# document create

        
          
          
              
              private void CreateWordDocument(string header, string wholeData)
{
    Microsoft.Office.Interop.Word.Application winword = null;
    Microsoft.Office.Interop.Word.Document document = null;
 
    try
    {
        // Initialize Word application
        winword = new Microsoft.Office.Interop.Word.Application
        {
            ShowAnimation = false,
            Visible = false
        };
 
        // Create a new document
        object missing = System.Reflection.Missing.Value;
        document = winword.Documents.Add(ref missing, ref missing, ref missing, ref missing);
 
        // Add Header
        AddParagraph(document, header, "Heading 1");
 
        // Add Content
        AddParagraph(document, wholeData, fontSize: 14);
 
        // Add Table
        AddSampleTable(document);
 
        // Save Document
        string sanitizedHeader = ReplaceInvalidFileNameChars(header);
        string filePath = $@"C:\YourOutputPath\{sanitizedHeader}.docx";
        document.SaveAs2(filePath);
    }
    catch (Exception ex)
    {
        Console.WriteLine($"Error: {ex.Message}");
    }
    finally
    {
        // Cleanup
        document?.Close(false);
        winword?.Quit(false);
    }
}
 
private void AddParagraph(Microsoft.Office.Interop.Word.Document document, string text, string style = null, int? fontSize = null)
{
    object missing = System.Reflection.Missing.Value;
    var paragraph = document.Content.Paragraphs.Add(ref missing);
 
    if (!string.IsNullOrEmpty(style))
    {
        paragraph.Range.set_Style(style);
    }
 
    if (fontSize.HasValue)
    {
        paragraph.Range.Font.Size = fontSize.Value;
    }
 
    paragraph.Range.Text = text;
    paragraph.Range.InsertParagraphAfter();
}
 
private void AddSampleTable(Microsoft.Office.Interop.Word.Document document)
{
    object missing = System.Reflection.Missing.Value;
    var range = document.Content.Paragraphs[1].Range; // Use the first paragraph's range
    var table = document.Tables.Add(range, 2, 1, ref missing, ref missing);
 
    table.Borders.Enable = 1;
    foreach (Row row in table.Rows)
    {
        foreach (Cell cell in row.Cells)
        {
            if (cell.RowIndex == 1)
            {
                cell.Range.Text = $"Sample Code {cell.ColumnIndex}";
                cell.Range.Font.Bold = 1;
                cell.Range.Font.Name = "Verdana";
                cell.Shading.BackgroundPatternColor = WdColor.wdColorGray25;
                cell.VerticalAlignment = WdCellVerticalAlignment.wdCellAlignVerticalCenter;
                cell.Range.ParagraphFormat.Alignment = WdParagraphAlignment.wdAlignParagraphCenter;
            }
            else
            {
                cell.Range.Text = "SQL or C# code sample will appear here";
            }
        }
    }
}
 
private string ReplaceInvalidFileNameChars(string input)
{
    return string.Concat(input.Select(c => Path.GetInvalidFileNameChars().Contains(c) ? ' ' : c));
}

            

        
      

Usage

        
              CreateWordDocument("MyHeader", "This is the content of the document.");

In this example:

Header and Content: The Paragraph objects are used to add headers and content with specific styles and formatting.
Table Creation: A 1x2 table is created using the Tables.Add method, where each cell can contain custom text and formatting.
File Saving: The file is saved with a name derived from the header parameter. Special characters are removed to avoid errors.
