Answer 1

 //登陆
    protected void btnLogin_Click(object sender, EventArgs e)
    {
       
            string uid = this.txtuid.Text;
            string pwd = FormsAuthentication.HashPasswordForStoringInConfigFile(this.txtpwd.Text, "MD5");
            if (BLLHelper.IsHaveUid(uid, pwd))
            {
                Session["user"] = this.txtuid.Text;
                Response.Redirect("Myproject.aspx");
            }
            else
            {
                Response.Write("<script>alert('用户名或密码错误');</script>");
                CreateCourse();
            }
        }
            } <table style="width: 80%;" align="center">
        <tr>
            <td class="style1">
                用户名：
            </td>
            <td class="style2">
                <asp:TextBox ID="txtuid" runat="server" Width="185px"></asp:TextBox>  
            </td>
            <td>
                <asp:RequiredFieldValidator ID="rfvuid" runat="server" ErrorMessage="用户名不能为空" ControlToValidate="txtuid"></asp:RequiredFieldValidator>   
            </td>
        </tr>
        <tr>
            <td class="style1">
                密码：
            </td>
            <td class="style2">
                <asp:TextBox ID="txtpwd" runat="server" TextMode="Password" 
                    style="margin-left: 0px; margin-bottom: 0px" Width="185px"></asp:TextBox>  
            </td>

            </td>
        </tr>
              <tr>
        <td colspan="3" align="center">
            <asp:Button ID="btnLogin" runat="server" Text="登陆" onclick="btnLogin_Click" />
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

51aspx.com里很多
  protected void Imgbtn_ok_Click(object sender, ImageClickEventArgs e)
        {
            if (Page.IsValid)
            {
                Sys_User user = SysUserBLL.SelectByUserId(Util.FormatInputStr(this.txtUser.Text));
                if (user != null)
                {
                    if (!user.PassWord.Equals(txtPwd.Text.Trim()))
                    {
                        new Jscript(this, "您输入的密码不对！").Show();
                        return;
                    }
                    else
                    {
                  
                        Session.Add("UserId", user.UserId);
                        
                        
                        this.Response.Write("<script language='javascript'>window.open('general/index.aspx','_self')</script>");
                    }
                }
                else
                {
                    new Jscript(this, "您没有任何权限！").Show();
                     return;
                }
            }
        }
