推荐答案

这是您问题的代码

here is the code for your problem

private void button1_Click(object sender, EventArgs e)
        {
            foreach(DataGridViewRow Row in dataGridView1.Rows)
            {
                if (Row.IsNewRow)
                {
                    
                }
                else if (Row.Cells[2].Value == null)
                {

                }
                else if (Row.Cells[2].Value.ToString() == bool.TrueString)
                {
                    Row.Cells[0].Value = "Accepted";
                    dataGridView1.Refresh();
                }
            }
        }

我检查了空值，因为当您不检查它时，它会给您一个错误

I checked for null value because when you leave one unchecked it will give you an error
