System.Web.Security.HashPasswordForStoringInConfigFile() 以下是引用片段：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) ;  }  if(code==32) //32位加密  {  return System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(str,"MD5").ToLower();  }  return "00000000000000000000000000000000"; 

}
