如何将VB.Net的CType()转换为C#

Question

我有以下代码段VB NET:

CType(pbImageHolder.Image, Bitmap).SetPixel(curPoint.X, curPoint.Y, Color.Purple)

什么是合适的代码C#？

先感谢您.

Answer 1

在VB.Net中,CType(object, type)将对象强制转换为特定类型.

在C#中有两种方法可以实现这一点:

Bitmap image = pbImageHolder.Image as Bitmap;
image.SetPixel(curPoint.X, curPoint.Y, Color.Purple);

要么

Bitmap image = (Bitmap)(pbImageHolder.Image);
image.SetPixel(curPoint.X, curPoint.Y, Color.Purple);

Answer 2

((Bitmap)pbImageHolder.Image).SetPixel(curPoint.X, curPoint.Y, Color.Purple)
