Answer 1

 int tempCount=dataGridView1.Rows.Count;
 for (int i = tempCount-1; i>0; i--)
            {
                if (dataGridView1.Rows[i].Cells[1].Selected)
                {
                    dataGridView1.Rows.RemoveAt(i);
                }
            }
试试

Answer 2

       private void button1_Click(object sender, EventArgs e)
        {
            for (int i = 0; i < dataGridView1.Rows.Count; i++)
            {
                if (dataGridView1.Rows[i].Cells[1].Selected)
                {
                    dataGridView1.Rows.RemoveAt(i);
                    dt.AcceptChanges();  //先设dt为全局，然后加这句试试
                }
            }
         
        }

Answer 3

这个需要从后往前删除。因为删除一行后，GriddView中的数据的顺序就会将删除后的序号自动-1
