嗨
如果您正在寻找C＃的方法，下面的解决方案是太容易解决方案：

Hi If you are looking a way in C# the below solution is too much easy solution:

private void buttonRemove_Click(object sender, EventArgs e)
    {
        foreach (DataGridViewCell oneCell in dataGridView1.SelectedCells)
        {
            if (oneCell.Selected)
                dataGridView1.Rows.RemoveAt(oneCell.RowIndex);
        }
    }

但是在C ++中就是这样，但是在C＃版本中你也可以使用它。 SelectedRows也是：

But in C++ it is like this, however in C# version you can use also .SelectedRows too:

foreach (DataGridViewRow row in DataGridView1.SelectedRows) 
{
    DataGridView1.Rows.Remove(row);
}

那不是C＃ - 它是C ++。



两者不可互换。



在C＃中，禁止操作：你不能改变列表foreach循环正在迭代，我会假设您的代码在尝试时抛出异常。

That's not C# - it's C++.

The two are not interchangeable.

In C#, that operation is forbidden: you cannot alter the list that a foreach loop is iterating through, and I would assume that your code is throwing an exception when you try.
