public static string GetEncodingString(string srcString)
        {
            Encoding e8859Encode = Encoding.GetEncoding("iso-8859-1");
            Encoding srcEncode = Encoding.GetEncoding("gb2312");
            Encoding dstEncode = Encoding.Unicode;
            byte[] srcBytes = e8859Encode.GetBytes(srcString);//用iso-8859-1去转换源字符串
            byte[] dstBytes = Encoding.Convert(srcEncode, dstEncode, srcBytes);//但是，是从gb2312转到unicode的
            char[] dstChars = new char[dstEncode.GetCharCount(dstBytes, 0, dstBytes.Length)];
            dstEncode.GetChars(dstBytes, 0, dstBytes.Length, dstChars, 0);
            return new string(dstChars);
           
        }具体原因我推测是因为数据过来是ISO-8859-1,但.Net地层格处理成了Gb2312了，所以需要通过两种编码转换成Unicode才能正常显示，听说在Java中只要new String(s.getBytes("ISO-8859-1"),"gb2312");就OK了。

转换成ISO

        public static string GetISOEncodedString(string srcString)
        {
            if(bDBInfor) {
                Encoding e8859Encode = Encoding.GetEncoding("iso-8859-1");
                Encoding srcEncode = Encoding.Unicode;
                Encoding dstEncode = Encoding.GetEncoding("gb2312");
                byte[] srcBytes = srcEncode.GetBytes(srcString);//用Unicode去转换源字符串
                byte[] dstBytes = Encoding.Convert(srcEncode, dstEncode, srcBytes);//但是，是从gb2312转到unicode的
                char[] dstChars = new char[e8859Encode.GetCharCount(dstBytes, 0, dstBytes.Length)];
                e8859Encode.GetChars(dstBytes, 0, dstBytes.Length, dstChars, 0);
                return new string(dstChars);
            }
            return srcString;
        }
