[SOLVED] copy to clipboard in c# asp.net


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Windows.Forms; // step 1

namespace School.Admin

public partial class Test : System.Web.UI.Page
    protected void Page_Load(object sender, EventArgs e)

    [STAThreadAttribute] // step 2
    protected void LinkButton1_Click(object sender, EventArgs e)
        Clipboard.SetText("Why it did not copy the words"); //step 3


the erorr is:

The current thread must be set to Single Thread Apartment (STA) mode before OLE calls can be made. Make sure the Main function is checked


you should use a piece of 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.setSelectionRange(0, 99999); /* For mobile devices */

              /* Copy the text inside the text field */
        <form id="form1" runat="server">
            <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')" />
