汉字与十六进制之间的相互转换
汉字与⼗六进制之间的相互转换1. 汉字转⼗六进制
public static string GBToUnicode(string text) {
byte[] bytes = System.Text.Encoding.Unicode.GetBytes(text);
string lowCode = "", temp = "";
for (int i = 0; i < bytes.Length; i++) {
if (i % 2 == 0) {
temp = System.Convert.ToString(bytes[i], 16);//取出元素4编码内容(两位16进制)
if (temp.Length < 2) temp = "0" + temp;
} else {
string mytemp = Convert.ToString(bytes[i], 16);
if (mytemp.Length < 2) mytemp = "0" + mytemp;
lowCode = lowCode + @"\u" + mytemp + temp;//取出元素4编码内容(两位16进制)
}
}
return lowCode;
}
2. ⼗六进制与汉字之间的相互转换
///<summary>
///汉字转换为Unicode编码
///</summary>
///<param name="str">要编码的汉字字符串</param>
///<returns>Unicode编码的的字符串</returns>
public static string ToUnicode(string str)
{
byte[] bts = Encoding.Unicode.GetBytes(str);
string r = "";
for (int i = 0; i < bts.Length; i += 2) r += "" + bts[i + 1].ToString("x").PadLeft(2, '0') + bts[i].ToString("x").PadLeft(2, '0');
return r;
}
/**/
///<summary>
///将Unicode编码转换为汉字字符串
///</summary>
///<param name="str">Unicode编码字符串</param>
///<returns>汉字字符串</returns>
public static string ToGB2312(string str)
{
string r = "";
MatchCollection mc = Regex.Matches(str, @"\\u([\w]{2})([\w]{2})", RegexOptions.Compiled | RegexOptions.IgnoreCase);
byte[] bts = new byte[2];
foreach (Match m in mc)
{
bts[0] = (byte)int.Parse(m.Groups[2].Value, NumberStyles.HexNumber);
bts[1] = (byte)int.Parse(m.Groups[1].Value, NumberStyles.HexNumber);
r += Encoding.Unicode.GetString(bts);
}
return r;
}
3. 字符串转⼗六进制
buffer[i] = (byte)Convert.ToByte(str.Substring(i, 2), 16);
4. ⼗六进制转字符串
strRecieve += Convert.ToString(buffer[i], 16).PadLef(2, '0').PadRight(3, '').ToUpper();或:
strRecieve += buffer[i].ToString("X2").PadRight(3,'');
5. 字节数组转⼗六进制
///<summary>
/
//字节数组转16进制字符串
///</summary>
///<param name="bytes">字节数组</param>
///<returns></returns>
public static string byteToHexStr(byte[] bytes)
{
string returnStr = "";
if (bytes != null)
{
for (int i = 0; i < bytes.Length; i++)
{
returnStr += bytes[i].ToString("X2");
}
}
汉字编码return returnStr;
}
