C# datagridview c键盘上的多项选择

我需要为datagridview创建一些键盘快捷键。 我需要允许用户不使用鼠标选择多行。e、 g.在windows资源管理器中，您可以： 按住Ctrl键并首先选择 向上/向下移动到下一个选择 空间选择其他人。

这在C语言中是可能的吗？

是的，这是可能的。因为Ctrl+←→↑↓ 已经有了默认行为，例如分别导航到最左边、最右边、最上面和最下面的单元格，您必须继承DataGridView类并重写ProcessDataGridViewKey方法来处理这些用户操作以及Ctrl+Space来选择行

public class MultSelectKeyDGV : DataGridView
{
    protected override bool ProcessDataGridViewKey(KeyEventArgs e)
    {
        KeyEventArgs keyEventArgs = null;
        DataGridViewSelectedCellCollection selectedCells = null;
        bool selectRow = false;

        if (e.Control)
        {
            switch (e.KeyCode)
            {
                case Keys.Down:
                    keyEventArgs = new KeyEventArgs(Keys.Down);
                    selectedCells = this.SelectedCells;
                    break;
                case Keys.Up:
                    keyEventArgs = new KeyEventArgs(Keys.Up);
                    selectedCells = this.SelectedCells;
                    break;
                case Keys.Right:
                    keyEventArgs = new KeyEventArgs(Keys.Right);
                    selectedCells = this.SelectedCells;
                    break;
                case Keys.Left:
                    keyEventArgs = new KeyEventArgs(Keys.Left);
                    selectedCells = this.SelectedCells;
                    break;
                case Keys.Space:
                    keyEventArgs = new KeyEventArgs(Keys.None);
                    selectRow = true;
                    break;
                default:
                    keyEventArgs = e;
                    break;
            }
        }
        else
        {
            keyEventArgs = e;
        }

        bool result = base.ProcessDataGridViewKey(keyEventArgs);

        if (e.Control)
        {
            this.CurrentRow.Selected = selectRow;
            this.KeepSelected(selectedCells); 
        }

        return result;
    }

    private void KeepSelected(DataGridViewSelectedCellCollection selected)
    {
        if (selected != null && this.MultiSelect)
        {
            foreach (DataGridViewCell cell in selected)
            {
                cell.Selected = true;
            }
        }
    }
}

现在，只需将表单中DataGridView对象的实例替换为此类的实例，就完成了

Shift+箭头键应该可以正常工作。还是要突出显示非连续行？@OhBeWise是的，我是指非连续行。
