问题描述
限时送ChatGPT账号..
看看这段代码:
string s = "0x00A5";
Console.WriteLine(((char)s).ToString()); //Error
Console.WriteLine(((char)0x00A5).ToString());
我知道为什么会出现错误,但我不知道如何解决这个问题.
I know why there is an error but i have no Idea how to solve this.
有什么建议吗?
string stringHex = "7A";
int intFromHex = int.Parse(stringHex , System.Globalization.NumberStyles.HexNumber) + 30;
string hex = intFromHex.ToString("X");
switch(hex.Length)
{
case 2:
hex = "0x00" + hex;
break;
case 3:
hex = "0x0" + hex;
break;
case 4:
hex = "0x" + hex;
break;
}
char c = (char)hex;
string s = "0x00A5";
Console.WriteLine(((char)s).ToString());
Console.WriteLine(((char)0x00A5).ToString());
这是整个代码.我试图用随机的 unicode 字符生成一个字符串.
This is the whole Code. Im trying to generate a string with random unicode Chars.
推荐答案
如果你只想转换一个符号,把Convert
:
If you want to convert just one symbol, put Convert
:
string s = "0x00A5";
//
string result = ((char)Convert.ToInt32(s, 16)).ToString();
如果你想转换几个你必须用正则表达式提取它们:
If you want to convert several ones you have to extract them with regular expressions:
string s = "0x00A50x00200x0048";
// H
string result = Regex.Replace(s, "0x[0-9A-Fa-f]{4}",
match => ((char)Convert.ToInt32(match.Value, 16)).ToString());
