You wish to copy text to the clipboard.
The basic syntax is:
您希望将文本复制到剪贴板。基本语法是：
Clipboard.SetText("The text you want to copy");
But in order for it to work there is more work to put into it, use the links I provided. You can find further information hereand herefor c# and herefor ASP.net which is more relevant for you.
但是为了让它工作，还有更多的工作要做，请使用我提供的链接。您可以在此处和此处为 c# 和此处为 ASP.net找到更多信息，这与您更相关。
This code was taken from CodeProject link aformentioned, and should work by using different thread.
此代码取自上述 CodeProject 链接，应该使用不同的线程工作。
private static string _Val;
public static string Val
{
get { return _Val; }
set { _Val = value; }
}
protected void LinkButton1_Click(object sender, EventArgs e)
{
Val = label.Text;
Thread staThread = new Thread(new ThreadStart (myMethod));
staThread.ApartmentState = ApartmentState.STA;
staThread.Start();
}
public static void myMethod()
{
Clipboard.SetText(Val);
}

You must do this on the client side (your browser). Doing this in server side (ASP.NET) doesn't make sense.
您必须在客户端（您的浏览器）执行此操作。在服务器端 (ASP.NET) 中执行此操作没有意义。
Unfortunately, clipboard manipulation is not cross-browser. If you need it to be cross-browser, you have to use flash. Look at ZeroClipboard library.
不幸的是，剪贴板操作不是跨浏览器的。如果你需要它是跨浏览器，你必须使用闪存。查看ZeroClipboard 库。
Look at this jsfiddlefor a working example.
看看这个jsfiddle一个工作示例。
<script type="text/javascript" src="http://www.steamdev.com/zclip/js/jquery.zclip.min.js"></script>
<a id='copy' href="#">Copy</a>
<div id='description'>this seems awesome</div>
$(document).ready(function(){
$('a#copy').zclip({
path:'http://www.steamdev.com/zclip/js/ZeroClipboard.swf',
copy:$('div#description').text()
});
});
Then for further examples on how to use ZeroClipboard, look at their md.
然后有关如何使用 ZeroClipboard 的更多示例，请查看他们的md。

{
Clipboard.SetText(txtClipboard.Text);
}
private void btnPaste_Click(object sender, EventArgs e)
{
txtResult.Text = Clipboard.GetText();
}

Clipboard.SetText(textBox1.Text.ToString()); Everyone forgot to tell you about .ToString() method. That works 100%
Clipboard.SetText(textBox1.Text.ToString()); 每个人都忘了告诉你 .ToString() 方法。这 100% 有效
