IronWord How to Remove Spacing Between Paragraphs for Multi-Line Address Blocks

Overview

When you stack short lines like an address block in IronWord, the default paragraph spacing leaves a gap between each line. This article shows you how to remove that gap by setting an exact line-spacing rule on each paragraph. The approach is verified on IronWord 2026.4.1.

• IronWord 2026.4.1
• A .NET project

1. Create the document and list the lines you want to stack together.
2. For each line, create a Paragraph and set its LineSpacing to a LineSpacing object that uses the Exact rule. This gives each line a fixed height with no extra gap.
3. Add each paragraph to the document and save.

Complete working example:

WordDocument doc = new WordDocument();  
string[] addressLines = 
{   
   "Max Mustermann",   
   "Musterstraße 42",   
   "12345 Musterstadt",   
   "Deutschland" 
};  
foreach (string line in addressLines) 
{
    Paragraph para = new Paragraph(new TextContent(line));
    para.LineSpacing = new IronSoftware.Abstractions.Word.LineSpacing()
    {
        LineSpacingRule = IronSoftware.Abstractions.Word.LineSpacingRules.Exact,
    };    doc.AddParagraph(para); }  doc.SaveAs("address3.docx");

Result:

Notes and Limitations

• Do not use the ParagraphSpacing class. It is not available in IronWord 2026.4.1, even though it appears in some examples.
• In 2026.4.1, setting SpacingBefore and SpacingAfter to 0 does not work as expected. The paragraph text becomes invisible while the paragraph stays in the document. This behavior is under investigation. Use the exact line-spacing rule shown above instead.
• Alternative: para.SpacingBetweenLines = 210 also produces tight spacing if you prefer to set an explicit value.
• Available types and properties vary by version. The line-spacing types here live in the IronSoftware.Abstractions.Word namespace.
