How to find an assembly reference
I have developed a code which copy and paste text and an image, but .net says this code is missing an assembly reference. I don't know how to find that reference. Please advise
Below is my code
============================
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace Clipboard
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btnCopytext_Click(object sender, EventArgs e)
{
Clipboard.SetText(txtClipboard.Text);
}
private void btnPastetext_Click(object sender, EventArgs e)
{
txtClipboard.Text = Clipboard.GetText();
}
private void btnCopyimg_Click(object sender, EventArgs e)
{
if (opnImage.ShowDialog() == DialogResult.OK)
{
Image imgtoCopy = Image.FromFile(opnImage.FileName);
Clipboard.SetImage(imgtoCopy);
}
}
private void btnPasteimg_Click(object sender, EventArgs e)
{
picClipBoard.Image = Clipboard.GetImage();
}
private void btnClearClipboard_Click(object sender, EventArgs e)
{
Clipboard.Clear();
}
}
}
