How to create barcodes through URL in C#
ASP.NET web app?

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddHttpContextAccessor();
var app = builder.Build();
// Linear
app.MapGet("/", async (IHttpContextAccessor httpContextAccessor) =>
{
    var context = httpContextAccessor.HttpContext;
    if (context != null)
        await OnBarcode.Barcode.ASPNETCore.LinearWebStream.drawBarcodeAsync(context.Request, context.Response);
});
// PDF417
app.MapGet("/PDF417", async (IHttpContextAccessor httpContextAccessor) =>
{
    var context = httpContextAccessor.HttpContext;
    if (context != null)
        await OnBarcode.Barcode.ASPNETCore.PDF417WebStream.drawBarcodeAsync(context.Request, context.Response);
});
// DataMatrix
app.MapGet("/DataMatrix", async (IHttpContextAccessor httpContextAccessor) =>
{
    var context = httpContextAccessor.HttpContext;
    if (context != null)
        await OnBarcode.Barcode.ASPNETCore.DataMatrixWebStream.drawBarcodeAsync(context.Request, context.Response);
});
// QRCode
app.MapGet("/QRCode", async (IHttpContextAccessor httpContextAccessor) =>
{
    var context = httpContextAccessor.HttpContext;
    if (context != null)
        await OnBarcode.Barcode.ASPNETCore.QRCodeWebStream.drawBarcodeAsync(context.Request, context.Response);
});
// MicroPDF417
app.MapGet("/MicroPDF417", async (IHttpContextAccessor httpContextAccessor) =>
{
    var context = httpContextAccessor.HttpContext;
    if (context != null)
        await OnBarcode.Barcode.ASPNETCore.MicroPDF417WebStream.drawBarcodeAsync(context.Request, context.Response);
});
// MicroQRCode
app.MapGet("/MicroQRCode", async (IHttpContextAccessor httpContextAccessor) =>
{
    var context = httpContextAccessor.HttpContext;
    if (context != null)
        await OnBarcode.Barcode.ASPNETCore.MicroQRCodeWebStream.drawBarcodeAsync(context.Request, context.Response);
});
app.Run();
