private string verCodeToString(Bitmap bitmap)

return str;
}

private string getStringCharByFlag(int flag)
{
string ret;
switch (flag)
{
case 12:
ret = "1";
break;
case 9:
ret = "2";
break;
case 13:
ret = "3";
break;
case 0:
ret = "4";
break;
case 7:
ret = "5";
break;
case 14:
ret = "6";
break;
case 1:
ret = "7";
break;
case 15:
ret = "8";
break;
case 11:
ret = "9";
break;
case 10:
ret = "0";
break;
default:
ret = "?";
break;
}
return ret;
}
只适用于简单验证码识别，复杂的要用更难的算法，不会再问我追问把能识别复杂验证码的源码文件发我邮箱，谢了！
