5、類文件中添加如下代碼
///
/// 驗證顧客登陸///
///
查詢語句
/// 指定顧客數(shù)據(jù)集
public dataset customerlogin(string sqlstr)
{
sqlcommand comm = new sqlcommand(sqlstr, conn);
sqldataadapter adapter = new sqldataadapter(comm);
dataset dbset = new dataset();
();
(dbset);
e();
();
return dbset;
}
6、將用戶登錄功能代碼改為:
string customername = ;
string customerpwd =
sswordforstoringinconfigfile, “md5”);
string sqlstring = “select * from test where uname=” + customername + “and upwd=” + customerpwd + “”;
da mydata=new da() ;
dataset ds = erlogin(sqlstring);
if ([0] == 0)
{
(“”);
}
else
{
//(“”);string scriptstring =(“登錄成功!”);
(scriptstring);
}
