我需要能够使用十六进制字符串并将其转换为.NET 中的实际十六进制值。 我该怎么做?

例如,在德尔菲,你可以采取一连串的“FF”,然后加上美元符号。

tmpstr :=  $ +  FF ;

然后,将 tmpstr 字符串变量转换成整数,以获得实际的十六进制。结果将是 255

最佳回答

假设您正在尝试将 string 转换为 :

var i = Int32.Parse("FF", System.Globalization.NumberStyles.HexNumber)

您的示例 1847504890 不适合 int 。 请使用更长的型号 。

var i = Int64.Parse("1847504890", System.Globalization.NumberStyles.HexNumber)
问题回答

非常简单 :

int value = 转换. Toint32 ("DEADDEEEF", 16);

你可以通过跟随它来做到这一点

string tmpstr = "FF";
int num = Int32.Parse(tmpstr, System.Globalization.NumberStyles.HexNumber);

int hexval = Convert.ToInt32("FF", 16);
