This guide explains how to create a program that uses DsPdf .NET to generate and save to disk a PDF file with the "Hello, World!" text.
Document Solutions for PDF .NET assemblies are built for .NET Standard 2.0, and can be used with any target that supports it. In this short tutorial, we show how to build a .NET console application. The tutorial takes you through the steps required to do that in Visual Studio on Windows, or Visual Studio Code on macOS and Linux.
This will add the required references to your application. You can now jump to Adding Code topic below to modify the application so that it generates the PDF.
$ mkdir ~/MyApp # create a directory for the application$ cd ~/MyApp$ dotnet new console # create a .NET console application with MyApp.csproj and Program.cs files$ dotnet add package DS.Documents.Pdf # add a reference to the package and fetch it<Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <OutputType>Exe</OutputType> <TargetFramework>net8.0</TargetFramework> </PropertyGroup> <ItemGroup> <PackageReference Include="DS.Documents.Pdf" Version="9.2.2" /> </ItemGroup></Project>$ cd ~/MyApp$ dotnet run # runs the default appAt this point you should see the "Hello, World!" printed in the terminal window (the default behavior of a new console app). Now modify the application so that it generates the PDF instead.
using System;using System.Drawing;using GrapeCity.Documents.Pdf;using GrapeCity.Documents.Text;
namespace MyApp{ class Program { static void Main(string[] args) { // Create a new PDF document: GcPdfDocument doc = new GcPdfDocument(); // Add a page, get its graphics: GcPdfGraphics g = doc.NewPage().Graphics; // Render a string into the page: g.DrawString("Hello, World!", // Use a standard font (the 14 standard PDF fonts are built into DsPdf .NET // and are always available): new TextFormat() { Font = StandardFonts.Times, FontSize = 12 }, // DsPdf .NET page coordinates start at top left corner, using 72 dpi by default: new PointF(72, 72)); // Save the PDF: doc.Save("HelloWorld.pdf"); } }}$ cd ~/MyApp$ dotnet run # runs MyAppThat's all it takes to generate a PDF file using DsPdf .NET. The HelloWorld.pdf should now appear in your project directory.
Essentially the same program is implemented by the Hello, World! sample, so you can see it in action:
