代码
private system.predicate<system.web.ui.control> ispreventcontrol = t => (t is system.web.ui.webcontrols.button) ||
(t is system.web.ui.webcontrols.linkbutton) ||
(t is system.web.ui.webcontrols.imagebutton) ||
(t is system.web.ui.htmlcontrols.htmlbutton) ||
//(t is system.web.ui.htmlcontrols.htmllink) ||
(t is system.web.ui.htmlcontrols.htmlinputbutton) ||
(t is system.web.ui.htmlcontrols.htmlinputsubmit);
如果你还是觉得效率不好那么，你就可以自己add或者addrange，同时包括了remove，insert等方法，这一系列方法都支持链式操作（这是第一次使用jquery的时候给我的最大触动）。例如：dsp.add(button1).add(button2).add(button3).add(linkbutton1).add(linkbutton2) =dsp.addrange(button1,button2,button3,linkbutton1,linkbutton2);包括的多个重载;
说了这么多还是直接上代码：
namespace wolf.utils
{
public class doublesubmitprevent
{
private system.collections.generic.list<string> _clientidlist = null;
private const string double_submit_prevent_str = "b3f6f682-f404-4519-9f30-79876e5a5c9a_wolf_doublesubmitprevent_391b8d4f-757e-4005-8262-062652d8bac6";
private bool isautofind = false;
#region judje prevent control?
private system.predicate<system.web.ui.control> ispreventcontrol = t => (t is system.web.ui.webcontrols.button) ||
(t is system.web.ui.webcontrols.linkbutton) ||
(t is system.web.ui.webcontrols.imagebutton) ||
(t is system.web.ui.htmlcontrols.htmlbutton) ||
//(t is system.web.ui.htmlcontrols.htmllink) ||
(t is system.web.ui.htmlcontrols.htmlinputbutton) ||
(t is system.web.ui.htmlcontrols.htmlinputsubmit);

protected virtual void doublesubmitpreventpageprerenderhick(object sender, system.eventargs e)
system.web.ui.page page = sender as system.web.ui.page;
if (page != null)
{
if (isautofind)
{
#region find action
system.action<system.collections.generic.list<string>, system.web.ui.control> action = null;
action = (list, ctr) =>
{
if (ctr != null)
{
if (ispreventcontrol(ctr))
{
list.add(ctr.clientid);
}
foreach (system.web.ui.control item in ctr.controls)
action(list, item);
}
};
#endregion
action(_clientidlist, basecontrlforfind);
}
system.text.stringbuilder sb = new system.text.stringbuilder();
foreach (var item in _clientidlist)
sb.append(string.format(" document.getelementbyid(\"{0}\").disabled=true;", item));
}
page.clientscript.registeronsubmitstatement(this.gettype(), double_submit_prevent_str, sb.tostring());
}
}
为了模拟延时，我在后台加了睡眠：
protected void page_load(object sender, eventargs e)
{
if (ispostback)
{
system.threading.thread.sleep(1000 * 5);
textbox1.text = datetime.now.tostring();
button3.enabled = false;
}
wolf.utils.doublesubmitprevent dsp = new wolf.utils.doublesubmitprevent(this) { isautofind = true, basecontrlforfind = this.form1 };
//dsp.add(button1).add(button2).add(button3).add(linkbutton1).add(linkbutton2);
}
<form id="form1" runat="server">
<asp:textbox id="textbox1" runat="server"></asp:textbox>
<asp:button id="button1" runat="server" text="button" enabled="false" />
<asp:button id="button2" runat="server" text="button" />
<asp:button id="button3" runat="server" text="button" />
<asp:linkbutton id="linkbutton1" runat="server">linkbutton</asp:linkbutton><asp:linkbutton
id="linkbutton2" runat="server">linkbutton</asp:linkbutton>
</form>
效果：
如果你又更好的方案，也希望能给我分享，请大家多多指教。
