推荐答案

这段代码尝试

更新的代码：

UPDATED CODE:

        private void richTextBox1_MouseUp(object sender, MouseEventArgs e)
        {
            if (e.Button == System.Windows.Forms.MouseButtons.Right)
            {   //click event
                //MessageBox.Show("you got it!");
                ContextMenu contextMenu = new System.Windows.Forms.ContextMenu();
                MenuItem menuItem = new MenuItem("Cut");
                menuItem.Click += new EventHandler(CutAction);
                contextMenu.MenuItems.Add(menuItem);
                menuItem = new MenuItem("Copy");
                menuItem.Click += new EventHandler(CopyAction);
                contextMenu.MenuItems.Add(menuItem);
                menuItem = new MenuItem("Paste");
                menuItem.Click += new EventHandler(PasteAction);
                contextMenu.MenuItems.Add(menuItem);

                richTextBox1.ContextMenu = contextMenu;
            }
        }
        void CutAction(object sender, EventArgs e)
        {
            richTextBox1.Cut();
        }

        void CopyAction(object sender, EventArgs e)
        {
            Graphics objGraphics;
            Clipboard.SetData(DataFormats.Rtf, richTextBox1.SelectedRtf);
            Clipboard.Clear();
        }

        void PasteAction(object sender, EventArgs e)
        {
            if (Clipboard.ContainsText(TextDataFormat.Rtf))
            {
                richTextBox1.SelectedRtf
                    = Clipboard.GetData(DataFormats.Rtf).ToString();
            }
        } 

的如果您要复制另一个粘贴应用程序如记事本（无伴奏）请更换以下方法的

if you want to copy paste with another application like notepad (without styles ) please replace following methods

       void CopyAction(object sender, EventArgs e)
        {
            Clipboard.SetText(richTextBox1.SelectedText);
        }

        void PasteAction(object sender, EventArgs e)
        {
            if (Clipboard.ContainsText())
            {
                richTextBox1.Text
                    += Clipboard.GetText(TextDataFormat.Text).ToString();
            }
        }
