[a280236121]

<form id="form1" runat="server">
用户名 :
<asp:TextBox ID="username" runat="server"></asp:TextBox>
<br />
密  码:
<input id="Password1" type="password" runat="server" />
<br />
<input id="Button1" type="submit" runat="server" value="登陆" onclick="Button1_Click" />
</form>


public void Button1_Click(object sender, EventArgs e)
{
string username = this.username.Text;
string pass = this.Password1.Value;

if (string.IsNullOrEmpty(username) || string.IsNullOrEmpty(pass))
{
Response.Write("<script type='text/javascript'>alert('用户名或密码不得为空');</script>");
this.username.Focus();
}
DataTable dtlogin = DBHelper.GetDataTable("SESECT FID,FPass FROM T_USER");
for (int i = 0; i <= dtlogin.Rows.Count; i++)
{
if (username.Equals(dtlogin.Rows[i]["FID"])&&pass.Equals(dtlogin.Rows[i]["FPass"]))
{
Response.Redirect("Message.aspx");
Response.End();
}
}
}

为什么跳转不了 是我哪里写错了嘛? 求助

<asp:Button ID="Button2" runat="server" OnClick="Button2_Click" Text="Button" /> 按钮 换成控件按钮 就可以了吧
