错误是:

最佳答案
你应该使用一段js
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Copy to Clipboard</title>
<script type="text/javascript">
function CopyToClipboard(myID)
{
var copyText = document.getElementById(myID);
/* Select the text field */
copyText.select();
copyText.setSelectionRange(0, 99999); /* For mobile devices */
/* Copy the text inside the text field */
document.execCommand("copy");
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Copy Text Box Text to Clip board" OnClientClick="CopyToClipboard('TextBox1')" />
</div>
</form>
</body>
</html>
