Answer 1

public string ChangeCode(string str)
{
string gb2312info = str;
string utfinfo = string.Empty;Encoding utf8 = Encoding.UTF8;
Encoding gb2312 = Encoding.GetEncoding("gb2312");
byte[] unicodeBytes = gb2312.GetBytes(gb2312info);
byte[] asciiBytes = Encoding.Convert(gb2312, utf8, unicodeBytes);
char[] asciiChars = new char[utf8.GetCharCount(asciiBytes, 0, asciiBytes.Length)];
utf8.GetChars(asciiBytes, 0, asciiBytes.Length, asciiChars, 0);
utfinfo = new string(asciiChars);return utfinfo;
}

Answer 3

Encoding gb2312 = Encoding.GetEncoding("gb2312");  都能为utf-7 是datagrid!导出没问题了!你搜索一下   datagrid   到处乱码! 就知道了 utf-7

Answer 4

WebConfig中
<globalization requestEncoding="UTF-8" responseEncoding="UTF-8" />
将UTF-8改称GB2312
