//这个不需要数据库,先把你说的控件放到Form1窗体上
public Form1()
{
InitializeComponent();
_dt.Columns.Add(new DataColumn("Value", typeof(string)));
}
private readonly DataTable _dt = new DataTable();
private void button1_Click(object sender, EventArgs e)
{
_dt.Rows.Add(textBox1.Text);
dataGridView1.DataSource = _dt;
}
public Form1()
{
InitializeComponent();
_dt.Columns.Add(new DataColumn("Value", typeof(string)));
}
private readonly DataTable _dt = new DataTable();
private void button1_Click(object sender, EventArgs e)
{
_dt.Rows.Add(textBox1.Text);
dataGridView1.DataSource = _dt;
}
