Save Generated Barcodes

The Aspose.BarCode Cloud SDK for .NET by the IGenerateApi provides methods to generate barcodes to the Task<System.IO.Stream>. Then you can work with result in order to obtain the desired outcomes. This API supports various barcode formats and configurations, enabling users to customize barcode generation to fit their needs.

Methods

  • GenerateAsync: Generates a barcode via GET request.
  • GenerateBodyAsync: Generates a barcode via POST request with JSON or XML body.
  • GenerateMultipartAsync: Generates a barcode via POST request with multipart form data. All of these methods return a Task<System.IO.Stream>.

Saving the Barcode to File

Below are examples demonstrating how to save the generated barcode stream to a file.

Example: Using GenerateAsync

using Aspose.BarCode.Cloud.Sdk.Api;
using Aspose.BarCode.Cloud.Sdk.Interfaces;
using Aspose.BarCode.Cloud.Sdk.Model;

using System;
using System.IO;
using System.Reflection;
using System.Threading.Tasks;

namespace GenerateSnippets;

internal static class Program
{
    private static Configuration MakeConfiguration()
    {
        var config = new Configuration();

        string? envToken = Environment.GetEnvironmentVariable("TEST_CONFIGURATION_ACCESS_TOKEN");
        if (string.IsNullOrEmpty(envToken))
        {
            config.ClientId = "Client Id from https://dashboard.aspose.cloud/applications";
            config.ClientSecret = "Client Secret from https://dashboard.aspose.cloud/applications";
        }
        else
        {
            config.JwtToken = envToken;
        }

        return config;
    }

    public static async Task Main(string[] args)
    {
        string fileName = Path.GetFullPath(Path.Join("Tests", "test_data",
            "Code128.jpeg"
        ));

        GenerateApi generateApi = new GenerateApi(MakeConfiguration());

        using var generated = await generateApi.GenerateAsync(EncodeBarcodeType.Code128, "Aspose.BarCode.Cloud", imageFormat: BarcodeImageFormat.Png);

        await using FileStream stream = File.Create(fileName);
        await generated.CopyToAsync(stream);

        Console.WriteLine($"File '{fileName}' generated.");
    }
}

        GenerateApi generateApi = new GenerateApi(MakeConfiguration());

        var generateParams = new GenerateParams
        {
            BarcodeType = EncodeBarcodeType.Pdf417,
            EncodeData = new EncodeData { Data = "Aspose.BarCode.Cloud", DataType = EncodeDataType.StringData },
            BarcodeImageParams = new BarcodeImageParams

                ForegroundColor = "#FF5733",
                BackgroundColor = "#FFFFFF",
                ImageFormat = BarcodeImageFormat.Jpeg
            }
        };

        Stream generated = await generateApi.GenerateBodyAsync(generateParams);

        await using FileStream stream = File.Create(fileName);
        await generated.CopyToAsync(stream);

        Console.WriteLine($"File '{fileName}' generated.");
    }
