public static string Str2Hex(string s)
{
string result = string.Empty;
byte[] arrByte = System.Text.Encoding.GetEncoding("GB2312").GetBytes(s);
for(int i = 0; i < arrByte.Length; i++)
{
result += "&#x" + System.Convert.ToString(arrByte[i], 16) + ";"; //Convert.ToString(byte, 16)把byte转化成十六进制string
}
return result;
}
变成可以在网上传输的那种16进制编码,类似%8D%E2这种?这样的话,
用System.Web.HTTPUtility.URLEncode()就行。
光光10进制转换到16进制的话,可以用 bytes(i).ToString("X"),
这是将一个字节转换为一个16进制字符串,"X"表示大写16进制字符,用"x"可以得到小写的。

public string EncodingSMS(string s)

for(int i = 0; i < arrByte.Length; i++)

public string DecodingSMS(string s)

string result = string.Empty;
byte[] arrByte = new byte[s.Length / 2];
int index = 0;
for(int i = 0; i < s.Length; i += 2)
{
arrByte[index++] = Convert.ToByte(s.Substring(i,2),16); //Convert.ToByte(string,16)把十六进制string转化成byte
}
result = System.Text.Encoding.Default.GetString(arrByte);
return result;
}
加码解码的规则如下:
加码时将字符串中的所有字符转换成其对应的ASCII值的16进制值,例如:“A”的ASCII码值为65,以16进制值表示为41,故应发送两个字符“41”以代表字符“A”。
对于汉字则以其内码的16进制值来表示,如“测试”应为:B2E2CAD4。
原理:
string aaa = "AB测试";
byte[] bbb = System.Text.Encoding.Default.GetBytes(aaa);
string ccc = System.Text.Encoding.Default.GetString(bbb);
for(int i = 0; i < bbb.Length; i++)
{
Response.Write(System.Convert.ToString(bbb[i], 16));
}
Response.Write(ccc);
{
string result = string.Empty;
byte[] arrByte = System.Text.Encoding.GetEncoding("GB2312").GetBytes(s);
for(int i = 0; i < arrByte.Length; i++)
{
result += "&#x" + System.Convert.ToString(arrByte[i], 16) + ";"; //Convert.ToString(byte, 16)把byte转化成十六进制string
