谢谢你了，孟子E章译错误
说明: 在编译向该请求提供服务所需资源的过程中出现错误。请检查下列特定错误详细信息并适当地修改源代码。编译器错误信息: BC30205: 需要语句结束。源错误: 行 6：   <title>subscribe</title>
行 7：   <script runat="server" id="Script1">
行 8：  public void Page_Load(object sender,System.EventArgs e)
行 9：  {
行 10： System.DateTime t = System.DateTime.Now;
源文件: http://localhost/ierpii/subscribe.aspx    行: 8 我实验了下一下，不行呀你直接把你的script嵌入，提示上面的错误
虽然我用的是VB，你用c#
但不应该出现这个问题呀
孟子E章，给你看一下我的代码
<%@ Page Language="vb" Debug="true" AutoEventWireup="false" Codebehind="subscribe.aspx.vb" Inherits="ierpii.subscribe"%>
<%@ Register TagPrefix="ois" Namespace="Ois.Web.UI.WebControls" Assembly="Ois.Web" %>
<%@ Import Namespace="System.Drawing" %>
<%@ Import Namespace="System.Web.UI.WebControls" %><script runat="server">
public void Page_Load(object sender,System.EventArgs e)
{
System.DateTime t = System.DateTime.Now;
string s= "";
s = t.Year.ToString("####");
s+= t.Month.ToString("0#");
s+= t.Day.ToString("0#");
s+=(new System.Random().Next(0,9999)).ToString("000#");
txtAutoId.Text = s;
B.Attributes.Add("onload","setInterval('window.location.reload()',3000)");
}
</script><body id="B" runat="server" MS_POSITIONING="GridLayout">
<asp:textbox id="txtAutoId" style="Z-INDEX: 111; LEFT: 712px; POSITION: absolute; TOP: 56px"
runat="server" Width="108px">
因为代码太长，我只摘了些相关的
你帮着看一下问题出在那里？
<script runat="server">
public void Page_Load(object sender,System.EventArgs e)
{
System.DateTime t = System.DateTime.Now;
string s= "";
s = t.Year.ToString("####");
s+= t.Month.ToString("0#");
s+= t.Day.ToString("0#");
s+=(new System.Random().Next(0,9999)).ToString("000#");
Response.Write(s);
}
</script>
这些有用System.DateTime t = System.DateTime.Now;
string s= "";
s = t.Year.ToString("####");
s+= t.Month.ToString("0#");
s+= t.Day.ToString("0#");
s+=(new System.Random().Next(0,9999)).ToString("000#");
vb:Dim t As System.DateTime = System.DateTime.Now
Dim s as String = ""
s = t.Year.ToString("####")
s = s+ t.Month.ToString("0#")
s = s+t.Day.ToString("0#")
s = s+ (New System.Random().Next(0,9999)).ToString("000#")
