-----------------------------
两种调用方法
1、 string strUserPsw = Us***sw.Text.Trim();
string UserPassword = Sy***m.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(strUserPsw, "MD5");//md5加密
SqlServerDataBase obj = new SqlServerDataBase();
ob***nsert("insert into asUserInfo (UserName,UserPassword,Question,Answer,CreateTime) values('" + Us***ame.Text.Trim() + "','" + UserPassword + "','" + Qu***ion.Text.Trim() + "','" + An***r.Text.Trim() + "','" + Da***ime.Now.ToString() + "' )", null);
2、 private bool IsUsernameExist(string strUsername)
{
bool bRet = true;
SqlServerDataBase db = new SqlServerDataBase();
DataSet ds = db***lect("select * from asUserInfo where UserName = '" + strUsername + "'", null);
if (ds == null || ds***bles.Count == 0 || ds***bles[0].R***.Count == 0)
{
bRet = false;
}
else
{
bRet = true;
}
return bRet;
}
