关于byte[]数组转十六进制字符串: public static String getHexString(byte[] b) throws Exception { String result = ""; for (int i=0; i < b.length; i++) { result += Integer.toString( ( b[i] & 0xff ) + 0x100, 16).substring( 1 ); } return result; } public s
byte[] xx=Encoding.Default.GetBytes("12121232"); 插入数据库 string sqlStr = "update sys_tab t set t.big_logo =:BIG_LOGO,t.small_logo=:SMALL_LOGO where id=:ID"; OracleParameter[] parameterValue = { new OracleParameter(":BIG_LOGO",O
