c# - 在表单中输入的数据不会插入到表中

Question

我在数据表中看不到添加的数据这是代码:

我正在使用 Visual Studio 2010 Express。

private void button1_Click(object sender, EventArgs e)
{
    string t1 = textBox1.Text;

    SqlCeConnection conn =
       new SqlCeConnection(@"Data Source=|DataDirectory|\Database1.sdf");

    conn.Open();

    SqlCeCommand cmdInsert = conn.CreateCommand();
    cmdInsert.CommandText = "INSERT TO table_name (Column1) VALUES (t1)";

    cmdInsert.ExecuteNonQuery();

    conn.Close();
}

点击按钮后它没有插入数据表，它给我一个错误

cmdInsert.ExecuteNonQuery();

它调试了它，但是当我点击按钮时，它显示了一个错误提示

SqlCeException was unhandled. There was an error parsing the query. [ Token line number = 1,Token line offset = 8,Token in error = TO ]

Answer 1

尝试:

cmdInsert.Parameters.AddWithValue("@t1", textBox1.Text);
cmdInsert.CommandText = "insert INTO table_name (Column1) VALUES (@t1)";
