asp.net连接mysql怎么写登录代码
关键是把登录代码写在 类中
然后前台登录代码就只用就调用这个 类C# code:
using System;//这个类中要是有错请指出来，谢谢
using System.Data;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Configuration;
using MySql.Data.MySqlClient;
/// <summary>
///UserInfo 的摘要说明
/// </summary>
public class UserInfo
{
public string user_name;
public string password;
public string str = System.Configuration.ConfigurationManager.AppSettings["strconn"];
MySqlConnection conn = new MySqlConnection();
MySqlCommand cmd = new MySqlCommand();
public string User_Name
{
get
{
return user_name;
}
set
{
user_name = value;
}
}
public string Password
{
get
{
return password;
}
set
{
password = value;
}
}
public bool CheckLogin()
{
conn = new MySqlConnection(str);
string sql = "Select count(user_name) from bg_user where username=? and password =?";
