how to get index of the last selected row from a selection of rows in a DataGridView

Question

I have a DataGridView and when I select multiple rows, I want the index of the last selected row. In other words, how to get the maximum most index from a selection of rows.

e.g., if I select row0, row1 and row6, I want the output as "6".

Regards.

Answer 1

if (dataGridView1.SelectedRows.Count > 0)
{
    int lastIndex = dataGridView1.SelectedRows[dataGridView1.SelectedRows.Count - 1].Index;
}

Answer 2

var x = dataGridView1.SelectedRows.Cast<DataGridViewRow>().Max(row => row.Index);

is the same to:

var y = dataGridView1.SelectedRows.Cast<DataGridViewRow>().Last().Index;
