Question

System.Windows.Forms.DataGridViewCell并不包含“value”的定义

private void button7_Click(object sender, EventArgs e)
{
double score = 0;
double sum = 0;
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
score = dataGridView1.Rows[i].Cells[2].value;
sum+=score;
}
MessageBox.Show("+sum+");

Answer 1

dataGridView1.Rows[i].Cells[2].Value // upperCase
