在LINQ数据库中插入数据

Question

I wonder why I can't insert data into database using LINQ. I created Serviced-Base database.

When I run the program, there is no error, but still no data appears in database table.

private void button1_Click(object sender, EventArgs e)
{
    DataClasses1DataContext ds = new DataClasses1DataContext();
    Customer cst = new Customer();

    cst.CustName = textBoxNama.Text;
    cst.Phone = int.Parse(textBoxHP.Text);
    cst.CustAddress = textBoxAlamat.Text;

    ds.Customers.InsertOnSubmit(cst);

    try
    {
        ds.SubmitChanges();
        MessageBox.Show("Success");
    }
    catch (Exception )
    {   
        throw;
    }
}

请检查您是否连接到正确的数据库（检查连接字符串）。
