在c＃中将字符转换为CP1252 Hex(Convert character to CP1252 Hex in c#)

在c＃中将字符转换为CP1252 Hex(Convert character to CP1252 Hex in c#)

我写了一个函数将字符串转换为十六进制字符串。 所以“abc”将转换为“616263”。

这是功能：

private string StringToHex(string myString) { int ctr, li_max; string ls_hex = ""; li_max = myString.Length; for(ctr = 0; ctr < li_max; ctr++) ls_hex = ls_hex + (Convert.ToInt16(myString[ctr])).ToString("x2"); return ls_hex; }

但是，当我有像“<abc”这样的unicode字符时，我得到“2039616263”。 所以我的第一个角色转换为2039（unicode）。 我想得到“8B616263”（CP1252）。 见下图：

如何获取正确编码的十六进制值？ 即：8B而不是2039

I wrote a function to convert a string to a hex string. So "abc" would be converted to "616263".

Here is the function:

private string StringToHex(string myString) { int ctr, li_max; string ls_hex = ""; li_max = myString.Length; for(ctr = 0; ctr < li_max; ctr++) ls_hex = ls_hex + (Convert.ToInt16(myString[ctr])).ToString("x2"); return ls_hex; }

However, when I have unicode characters like "‹abc" I get "2039616263". So my first character is converted to 2039 (unicode). I wanted to get "8B616263" (CP1252). See image below:

How can I get the hex value for the correct encoding? ie: 8B instead of 2039

最满意答案

您需要使用CP1252编码来获取字符串的字节：

private string StringToHex(string myString) { byte[] bytes = Encoding.GetEncoding(1252).GetBytes(myString); return string.Concat(bytes.Select(b => b.ToString("X2"))); }

我的输出是

8B616263

You need to get use the CP1252 encoding to get the bytes of the string:

private string StringToHex(string myString) { byte[] bytes = Encoding.GetEncoding(1252).GetBytes(myString); return string.Concat(bytes.Select(b => b.ToString("X2"))); }

My output is

8B616263
