private void Form1_Load(object sender, EventArgs e)
{
    Load_Gender();
}

public void Load_Gender()
{
    try
    {
        string connectionString = @"Data Source=localhost;" +
      "Initial Catalog=DemoDb;Integrated Security=true; User Instance=False";

        SqlConnection connection = new lConnection(connectionString);
        SqlCommand command = new SqlCommand();
        command.Connection = connection;

        command.CommandText = "SELECT * FROM Gender";
        SqlDataAdapter sl = new SqlDataAdapter(command);

        DataSet ds = new DataSet();
        sl.Fill(ds, "Table");

        DataTable dt = ds.Tables["Table"];

        foreach (DataRow row in dt.Rows)
        {
            string id = row["Id"].ToString();
            string genderName = row["GenderName"].ToString();
        }

        // Loading RECORDS to comboBox
        for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
        {
            comboBoxGender.Items.Add(ds.Tables[0].Rows[i][0].ToString());
        }
    }
    catch()
    {
    }
}
