asp.net 中,如果要修改输出页面的编码,可以通过修改web.config中以下配置信息
<globalization requestEncoding="utf-8" responseEncoding="utf-8" />
以上只是修改整体的默认编码,如果只有某个页的编码需要修改,ASP.net 中则可以简单的使用下面代码:
Encoding gb2312 = Encoding.GetEncoding("gb2312"); Response.ContentEncoding = gb2312;
在非ASP.net 应用中,可能你读到的数据是UTF-8编码,但是你要转换为GB2312编码,则可以参考以下代码:
string utfinfo = "document.write(\"alert('aa你好么??');\");"; string gb2312info = string.Empty; Encoding utf8 = Encoding.UTF8; Encoding gb2312 = Encoding.GetEncoding("gb2312"); // Convert the string into a byte[]. byte[] unicodeBytes = utf8.GetBytes(utfinfo); // Perform the conversion from one encoding to the other. byte[] asciiBytes = Encoding.Convert(utf8, gb2312, unicodeBytes); // Convert the new byte[] into a char[] and then into a string. // This is a slightly different approach to converting to illustrate // the use of GetCharCount/GetChars. char[] asciiChars = new char[gb2312.GetCharCount(asciiBytes, 0, asciiBytes.Length)]; gb2312.GetChars(asciiBytes, 0, asciiBytes.Length, asciiChars, 0); gb2312info = new string(asciiChars);
