<span style="font-family: Arial, Helvetica, sans-serif; font-size: 12px; background-color: rgb(255, 255, 255);">1、在web.config中的设置</span>

    <system.web><span style="white-space:pre"></span>.......

<span style="white-space:pre"></span>.......

      <authentication mode="Forms">        <forms name=".loginAuth"        loginUrl="login.aspx"        defaultUrl="index.aspx"        path="/"        timeout="30">        </forms>      </authentication>      <authorization >        <allow users="*"/>      </authorization>    </system.web>  <location path="adm">    <system.web>      <authorization>        <deny users="?"/>      </authorization>    </system.web>  </location>

访问adm目录的文件要登入权限，自动转到login.aspx的登陆画面中

2、login.aspx判断是否有进入权限

                myCommand.CommandText = "SELECT ..... FROM userList WHERE (userName=@userName OR userPhone=@userName) AND userPass=@pass";                myCommand.CommandType = CommandType.Text;                SqlDataAdapter myAdapter = new SqlDataAdapter(myCommand);                DataSet myds = new DataSet();                myAdapter.Fill(myds);                if ( myds.Tables[0].Rows.Count > 0)                {                    DataRow myRow = myds.Tables[0].Rows[0];                    FormsAuthentication.RedirectFromLoginPage(myRow["userName"].ToString().Trim(), false);                    Response.Redirect("~/adm/adminLogin_b.aspx?uName=" + myRow["userName"].ToString().Trim());                }

认证通过则将登入的用户名放到FormsAuthentication中

3、登出

FormsAuthentication.SignOut();
