.NET Framework'te AnyBitmap to System.Drawing.Bitmap

.NET Framework masaüstü uygulamalarında WinForms gibi, bir IronBarcode AnyBitmap doğrudan bir System.Drawing.Image veya Bitmap atamak derleme zamanında başarısız olur. Yaygın bir durum, oluşturulan bir barkodu yalnızca System.Drawing.Image nesnelerini kabul eden bir PictureBox'a bağlamaktır.

Cannot implicitly convert type 'IronSoftware.Drawing.AnyBitmap' to 'System.Drawing.Image'

Aşağıdaki kod hata tetikler:

var myBarcode = BarcodeWriter.CreateBarcode("12345", BarcodeWriterEncoding.EAN8);
// These lines cause compile-time errors
Image myBarcodeImage = myBarcode.Image;
Bitmap myBarcodeBitmap = myBarcode.ToBitmap();

var myBarcode = BarcodeWriter.CreateBarcode("12345", BarcodeWriterEncoding.EAN8);
// These lines cause compile-time errors
Image myBarcodeImage = myBarcode.Image;
Bitmap myBarcodeBitmap = myBarcode.ToBitmap();

Dim myBarcode = BarcodeWriter.CreateBarcode("12345", BarcodeWriterEncoding.EAN8)
' These lines cause compile-time errors
Dim myBarcodeImage As Image = myBarcode.Image
Dim myBarcodeBitmap As Bitmap = myBarcode.ToBitmap()

Hem BarcodeWriter.Image hem de .ToBitmap() bir IronSoftware.Drawing.AnyBitmap döndürür. Bu tür, yalnızca .NET 6, .NET 7, .NET 8 veya üzeri sürümlerde System.Drawing.Bitmap veya Image'e örtük dönüştürmeyi destekler. .NET Framework'te örtük operatörler ve dahili tür köprüleme her zaman çözülmez, özellikle türler farklı kütüphanelerden veya uyumluluk katmanlarından geldiğinde.
