嗨，我正在尝试转换包含特殊字符（如û和）的字符串…。
在研究和测试中，我几乎成功使用了以下功能：
public static string ToHex(this string input)
{
char[] values = input.ToCharArray();
string hex = "0x";
string add = "";
foreach (char c in values)
{
int value = Convert.ToInt32(c);
add = String.Format("{0:X}", value).Length == 1 ?
"0" + String.Format("{0:X}", value) + "00"
: String.Format("{0:X}", value) + "00";
hex += add;
}
return hex;
}
如果我尝试´o¸sçPQ^ûË\u000f±d对其进行正确解码，然后将其转换为此0xB4006F00B8007300E700500051005E00FB00CB000F00B1006400，
而不是当我尝试解码´o¸sçPQ](ÂF\u0012…a失败，并把它变成0xB4006F00B8007300E700500051005D002800C200460012002026006100的，而不是这个0xB4006F00B8007300E700500051005D002800C2004600120026206100。
进行最少的调试时，我看到字符串从转换´o¸sçPQ](ÂF\u0012…a为´o¸sçPQ](ÂF.a，我不希望这样成为问题，但我不确定。

谢谢您的每一个回复或评论，
问候。
这是由于endianness和不同的整数和字符串编码所致。
char cc = '…';
Console.WriteLine(cc);
// 2026 <-- note, hex value differs from byte representation shown below
Console.WriteLine(((int)cc).ToString("x"));
// 26200000
Console.WriteLine(BytesToHex(BitConverter.GetBytes((int)cc)));
// 2620
Console.WriteLine(BytesToHex(Encoding.GetEncoding("utf-16").GetBytes(new[] { cc })));
您不应将char视为整数。有很多不同的方式来编码字符串，.net内部使用UTF-16。并且所有编码都使用字节，而不是整数。将字符显式转换为整数可能会导致出乎您意料的结果。为什么不获得所需的编码并通过来处理字节Encoding.GetBytes？
void Main()
{
// output you expect 0xB4006F00B8007300E700500051005D002800C2004600120026206100
Console.WriteLine(BytesToHex(Encoding.GetEncoding("utf-16").GetBytes("´o¸sçPQ](ÂF\u0012…a")));
}
public static string BytesToHex(byte[] bytes)
{
// whatever way to convert bytes to hex
return "0x" + BitConverter.ToString(bytes).Replace("-", "");
}
