Use the Bitmap Constructor Method
使用位图构造方法
Bitmap newBitmap = new Bitmap(width, height, Stride, PixelFormat, bitmapSource);

Since you are asking about BitmapSourceand your question is tagged with WPF, here's a way to avoid using System.Drawing.Bitmap:
由于您正在询问BitmapSource并且您的问题带有 标记WPF，因此有一种避免使用的方法System.Drawing.Bitmap：
Imaging.CreateBitmapSourceFromHBitmap(imagePointer, IntPtr.Zero, Int32Rect.Empty,
BitmapSizeOptions.FromEmptyOptions());
You'll need to use System.Windows.Interop.
