This program guide focus on helping you how to make Spire.Doc workable on Windows and Linux.

Starts from V 6.7.4, Spire.Doc supports .NET Core 2.0. Spire.Doc uses System.Drawing.Common, which depends on Libgdiplus library. So when you use Spire.Doc on .NET core, you need to install Libgdiplus library.

On Windows, we recommend you to get Spire.Doc package via Nuget. The Libgdiplus library will be installed automatically.

On Linux, you need to install Libgdiplus library independently. Please follow the below three steps to install it successfully.

Step1: Open xxxx.csproj file and write the code snippet into it.

<ItemGroup>
<PackageReference Include=”Spire.Doc” Version=”6.7.13”/>
</ItemGroup>

Step 2. Execute "dotnet build" command on terminal window of Visual Studio Code. It will install Spire.Doc package.

Step 3. Open terminal window on Linux and execute Libgdiplus library installation command, for example, the command on Linux Ubuntu is "sudo apt-get install libgdiplus".

Then you can use Spire.Doc on .NET core.

Delete a Specific Paragraph in a Word Document

Spire.Doc for .NET provides a method RemoveAt() under ParagraphCollection to remove paragraphs.

The detailed steps of removing a specific paragraph are as follows:

• Create an object of Document class.
• Load a Word document using Document.LoadFromFile() method.
• Get the first section using Document.Section[] property.
• Remove the 4th paragraph using Section.Paragraphs.RemoveAt() method.
• Save the document using Document.SaveToFile() method.

using System;
using Spire.Doc;

namespace RemoveParagraphs
{
    internal class Program
    {
        static void Main(string[] args)
        {
            //Create an object of Document class
            Document document = new Document();

            //Load a Word document
            document.LoadFromFile("Sample.docx");

            //Get the first section
            Section section = document.Sections[0];

            //Remove the first paragraph in the section
            section.Paragraphs.RemoveAt(3);
            
            //Save the document
            document.SaveToFile("RemoveParagraphs.docx", FileFormat.Docx2013);
        }
    }
}

Imports System
Imports Spire.Doc

Module Program
    Sub Main(args As String())
        'Create an object of Document class
        Dim document As Document = New Document

        'Load a Word document
        document.LoadFromFile("Sample.docx")

        'Get the first section
        Dim section As Section = document.Sections(0)

        'Remove the first paragraph in the section
        section.Paragraphs.RemoveAt(3)

        'Save the document
        document.SaveToFile("RemoveParagraphs.docx", FileFormat.Docx2013)
    End Sub
End Module

Delete All Paragraphs in a Word Document

To remove all paragraphs, you can use the method Clear() under ParagraphCollection provided by Spire.Doc for .NET.

The detailed steps are as follows:

• Create an object of Document class.
• Load a Word Document using Document.LoadFromFile() method.
• Loop through all sections, and remove all paragraphs in each section using Section.Paragraphs.Clear() method.
• Save the document using Document.SaveToFile() method.

using System;
using Spire.Doc;

namespace RemoveAllParagraphs
{
    internal class Program
    {
        static void Main(string[] args)
        {
            //Create an object of Document class
            Document document = new Document();

            //Load a Word document
            document.LoadFromFile("Sample.docx");

            //Loop through all sections
            foreach (Section section in document.Sections)
            {
                //Remove all paragraphs in the section
                section.Paragraphs.Clear();
            }

            //Save the document
            document.SaveToFile("RemoveAllParagraphs.docx", FileFormat.Docx2013);
        }
    }
}

Imports System
Imports Spire.Doc

Module Program
    Sub Main(args As String())
        'Create an object of Document class
        Dim document As Document = New Document()

        'Load a Word document
        document.LoadFromFile("Sample.docx")

        'Loop through all sections
        For Each section As Section In document.Sections
            'Remove all paragraphs in the section
            section.Paragraphs.Clear()
        Next

        'Save the document
        document.SaveToFile("RemoveAllParagraphs.docx", FileFormat.Docx2013)
