Getting Started with Aspose.Pdf in Visual Studio

In this section, we will explore how we can work with Aspose.Pdf in .NET. We will learn how to create a PDF document using the Aspose.Pdf API.

Here's the list of the steps that you would need to follow to create a PDF document using the Aspose API for .NET.

  1. Open Visual Studio 2017 (I'm using Visual Studio 2017 in my system though you can use the earlier versions, i.e., Visual Studio 2015 or Visual Studio 2013 as well)
  2. Create a new C# console application project
  3. Save the project with a name
  4. Next, create an instance of the Pdf class (this class is available as part of the Aspose.Pdf.Generator) namespace
  5. Specify the license (if you have purchased a license) using the License class
  6. Add one or more sections to the Pdf object. Note that the Sections collection is used to hold one or more sections.
  7. Add a text paragraph to the section you just created
  8. Lastly, call the Save method on the Pdf instance to generate your PDF document

And that's all you need to do to create a PDF document using the Aspose.Pdf API.

Applying the License

Applying the license to the Aspose.Pdf is simple. All you need to do is create an instance of the Aspose.Pdf.License class, call the SetLicense method and pass the license file name as a parameter to the method.

The easiest way to apply the license to Aspose.Pdf component is by placing the license file inside the same directory where the Aspose.dll resides. This way you would not have to have the hassle of passing path while specifying the license file name to the SetLicense method. The following code snippet shows how you instantiate the License class, load the license from a license file and then make a call to the SetLicense method to apply the license.

Aspose.Pdf.License license = new Aspose.Pdf.License();
license.SetLicense("Aspose.Pdf.lic");

            var pdf = new Pdf.Generator.Pdf();
            //Specify the license to be used
            var license = new License();
            license.SetLicense("Aspose.Pdf.lic");
            // Now, add a section into the pdf document
            var customSection = pdf.Sections.Add();
            // Next, add a text paragraph to the section just created
            customSection.Paragraphs.Add(new Text("This is a sample text"));
            // Save the document - this generates the document as well
            // The saved document is stored in the path mentioned
            pdf.Save("D:\\MySample.pdf");
        }

Note that the following namespaces should be included in your program for it to compile and work.

Aspose.Pdf;
Aspose.Pdf.Generator;
