Question

SharpDX kullanarak masaüstü ekran görüntüsü yakalamaya çalışıyorum. Uygulamam ekran görüntüsünü yakalayabiliyor ancak Windows Gezgini'nde etiketsiz. 2 çözüm denedim ama değişiklik yapmadan. Herhangi bir bilgiyi belgede bulmayı denedim, ama değişmeden. Gönderen

:

PixelFormat.Format32bppArgb 

için: i çalışma çözüm bulduk araştırma ve googling kaç saat sonra
