How Can I Monitor Clipboard Changes in C#?

Monitoring clipboard changes in C#

C# provides a way to monitor clipboard changes through events. This is especially useful if you need to update your application based on changes to the clipboard contents.

One way to monitor clipboard changes is to use the ClipboardMonitor control. This control can be added to your form and it will handle the WM_DRAWCLIPBOARD message, which is sent every time the clipboard contents change.

Here is a detailed example using the ClipboardMonitor control:

<code class="language-csharp">using ClipboardAssist;
using System;

namespace ClipboardMonitorExample
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            // 创建 ClipboardMonitor 控件。
            ClipboardMonitor clipboardMonitor = new ClipboardMonitor();

            // 设置 ClipboardChanged 事件的事件处理程序。
            clipboardMonitor.ClipboardChanged += ClipboardMonitor_ClipboardChanged;
        }

        private void ClipboardMonitor_ClipboardChanged(object sender, ClipboardChangedEventArgs e)
        {
            // 根据新的剪贴板内容更新应用程序。
            Console.WriteLine("剪贴板已更改：" + e.DataObject.GetData(DataFormats.Text));
        }
    }
}</code>

In this example, the ClipboardMonitor control raises the ClipboardChanged event whenever the clipboard contents change. The event handler for this event will then update the application accordingly.

Using the ClipboardMonitor control provides a convenient way to monitor clipboard changes and take appropriate action when necessary.
