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.

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

C#

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

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

C++

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