c# - 当用户从上下文菜单中选择 "Copy"时如何将数据复制到剪贴板

Question

当用户从特定单元格的上下文菜单中选择复制时，您如何将数据网格单元格的内容复制到剪贴板？

public Form1()
{
    InitializeComponent();
    dataGridView1.MouseClick += dataGridView1_MouseClick;
}

void dataGridView1_MouseClick(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Right)
    {
        ContextMenu m = new ContextMenu();
        m.MenuItems.Add(new MenuItem("Copy"));

        int currentMouseOuverRow = dataGridView1.HitTest(e.X, e.Y).RowIndex;

        m.Show(dataGridView1, new Point(e.X, e.Y));
    }
}

我想我会这样做:

var hitTestInfo = dataGridView1.HitTest(e.X, e.Y);
if (hitTestInfo.Type != DataGridViewHitTestType.Cell) { return; }

var mi = new MenuItem("Copy")
mi.Tag = hitTestInfo;
mi.Click += (s, e) =>
{
    var hti = ((MenuItem)s).Tag as HitTestInfo;
    var val = dataGridView1.Rows[hti.RowIndex].Cells[hti.ColumnIndex].Value;

    Clipboard.SetData(DataFormats.Text, val);
}

m.MenuItems.Add(mi);
