我想将int
转换为hex
字符串(此部分正常),然后将hex
字符串转换为{{1格式 byte
,以便将其用于数组。目前我已经有了这段代码:
0x(theHexString)
例如,int值为18,因此Hex字符串为1D(太棒了!)。但问题是我不知道为了获得0x1D字节我是否还要做其他事情......
感谢您的帮助!
答案 0 :(得分:1)
尝试使用带有数字基础的Convert.ToInt32
方法的重载:
int int32Value = Convert.ToInt32("1D", fromBase: 16);
byte byteValue = Convert.ToByte(int32Value);
我不确定是否理解了这个问题。
如果你的意思是你想要将十六进制值转换为它的C#表示(" 0xVALUE"),那么只需在生成的十六进制字符串的开头添加这些字符:
"1D".Insert(0, "0x");
无论如何,我做了这个功能,可以帮助你:
