Code Description:

Encoding UTF8 = encoding.getencoding (65001);//Use code page

Encoding gb2312 = encoding.getencoding ("gb2312");//Through Bodyname

Gets the character encoding byte sequence: byte[] Temp=utf8. GetBytes (str);

Encoding mode conversion: byte[] Temp1=encoding.convert (UTF8, gb2312, temp);

Gets the encoded string: string str1=gb2312. GetString (TEMP1);

This completes the conversion of the character encoding.

Encoding.default is generally the gb2312 format in the Simplified Chinese OS.
