//Load a sample Word document
doc.LoadFromFile(@"D:\Files\input.docx");
//Loop through all paragraphs in the document
foreach (Section section in doc.Sections)
{
for (int i = 0; i < section.Body.ChildObjects.Count; i++)
{
if (section.Body.ChildObjects[i].DocumentObjectType == DocumentObjectType.Paragraph)
{
//Determine if the paragraph is a blank paragraph
if (String.IsNullOrEmpty((section.Body.ChildObjects[i] as Paragraph).Text.Trim()))
{
//Remove blank paragraphs
section.Body.ChildObjects.Remove(section.Body.ChildObjects[i]);
i--;
}
}
}
}
//Save the document
doc.SaveToFile("RemoveEmptyLines.docx", FileFormat.Docx2013);
}
}
}

'Load a sample Word document
doc.LoadFromFile("D:\Files\input.docx")
'Loop through all paragraphs in the document
For Each section As Section In doc.Sections
For i As Integer = 0 To section.Body.ChildObjects.Count - 1
'Determine if the paragraph is a blank paragraph
If section.Body.ChildObjects(i).DocumentObjectType = DocumentObjectType.Paragraph Then
'Remove blank paragraphs
If String.IsNullOrEmpty((TryCast(section.Body.ChildObjects(i), Paragraph)).Text.Trim()) Then
section.Body.ChildObjects.Remove(section.Body.ChildObjects(i))
i -= 1
End If
End If
Next
Next
'Save the document
