如何在datagridview中添加和自定义行C＃

Question

我有以下代码

dataGridView1.ColumnCount = 3;
for (int i = 0; i <= dataGridView1.ColumnCount; i++)
{
    dataGridView1.Columns[i].Name = "Product ID" + i + "";
}

for (int j = 0; i <= 5; j++)
{
    dataGridView1.Rows.Add();
}

但是添加行的代码不起作用。 我需要在该网格中添加新行

Answer 1

将i <= dataGridView1.ColumnCount更改为

i < dataGridView1.ColumnCount

将i更改为j

for (int j = 0; i <= 5; j++)
{
    dataGridView1.Rows.Add();
}

最终结果是

dataGridView1.ColumnCount = 3;
for (int i = 0; i < dataGridView1.ColumnCount; i++)
{
     dataGridView1.Columns[i].Name = "Product ID" + i + "";
}

 for (int j = 0; j <= 5; j++)
 {
     dataGridView1.Rows.Add();
 }
