WebWhat I am doing is the following: int hex = (255 << 24) ( (byte)R << 16) ( (byte)G << 8) ( (Byte)B<<0); But when I do this, I just get blue. Any ideas what I am doing wrong? Also, to undo this, to check the RGB values, I am going: int r = ( (byte) (hex >> 16)); // = 0 int g = ( (byte) (hex >> 8)); // = 0 int b = ( (byte) (hex >> 0)); // = 255 WebDec 28, 2024 · 在写C#TCP通信程序时,发送数据时,只能发送byte数组,处理起来比较麻烦不说,如果是和VC6.0等写的程序通信的话,很多的都是传送结构体,在VC6.0中可以很方便的把一个char[]数组转换为一个结构体,而在C#却不能直接...
