根据组合框 c# 的选择，我的代码没有切换到所需的 function

Question

The code is not invoking the show_auto function even though I have selected the CHEMICAL from the drop down, it is always invoking the show_cement function.

private void gunaComboBox1_SelectedIndexChanged(object sender, EventArgs e) {
    ArrayList companyName = new ArrayList();
    ArrayList Price = new ArrayList();
    ArrayList category = new ArrayList();

    String selected = this.gunaComboBox1.GetItemText(this.gunaComboBox1.SelectedItem);

    if (selected.Equals("CHEMICAL")) {
        show_auto(companyName, Price, selected);
    } else {

        show_cement(companyName, Price, "CEMENT");
    }
}

Answer 1

String selected = gunaComboBox1.selecteditem.text;

and then compare with "CHEMICAL"
