ASP.NET和ASP的比较,技术上比较已经没什么可说的了.新一代在大部分程度来说当然是比旧一代好了. 关键看你对所做软件的理解了.因人而定.会写的话也可能比ASP.NET写得更有效率和更方便重用asp.net|加密 asp.net
援用内容:public string md5(string str,int code)
{
if(code==16) //16位MD5加密(取32位加密的9~25字符)
{
return System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(str,"MD5").ToLower().Substring(8,16) ;
}
else//32位加密
{
return System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(str,"MD5").ToLower();
}
