不同编码的页面、脚本之间互相引用,就会产生乱码的问题,解决方法就是统一成一种编码。
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
把UTF-8编码转换为GB2312编码<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:

把UTF-8编码转换为GB2312编码Encoding gb2312 = Encoding.GetEncoding("gb2312"); 把UTF-8编码转换为GB2312编码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:

 

把UTF-8编码转换为GB2312编码string utfinfo = "document.write(\"alert('aa你好么??');\");"; 把UTF-8编码转换为GB2312编码string gb2312info = string.Empty; 把UTF-8编码转换为GB2312编码把UTF-8编码转换为GB2312编码Encoding utf8 = Encoding.UTF8; 把UTF-8编码转换为GB2312编码Encoding gb2312 = Encoding.GetEncoding("gb2312"); 把UTF-8编码转换为GB2312编码把UTF-8编码转换为GB2312编码// Convert the string into a byte[]. 把UTF-8编码转换为GB2312编码byte[] unicodeBytes = utf8.GetBytes(utfinfo); 把UTF-8编码转换为GB2312编码// Perform the conversion from one encoding to the other. 把UTF-8编码转换为GB2312编码byte[] asciiBytes = Encoding.Convert(utf8, gb2312, unicodeBytes); 把UTF-8编码转换为GB2312编码把UTF-8编码转换为GB2312编码// Convert the new byte[] into a char[] and then into a string. 把UTF-8编码转换为GB2312编码// This is a slightly different approach to converting to illustrate 把UTF-8编码转换为GB2312编码// the use of GetCharCount/GetChars. 把UTF-8编码转换为GB2312编码char[] asciiChars = new char[gb2312.GetCharCount(asciiBytes, 0, asciiBytes.Length)]; 把UTF-8编码转换为GB2312编码gb2312.GetChars(asciiBytes, 0, asciiBytes.Length, asciiChars, 0); 把UTF-8编码转换为GB2312编码gb2312info = new string(asciiChars); 把UTF-8编码转换为GB2312编码
