推荐答案

private bool HidePanels()
{
    panel1.Visible = false;
    panel2.Visible = false;
    panel3.Visible = false;
}

在Form_Laod
中设置Comboes Tag =相关面板 例如:

Set Comboes Tag = related Panels in Form_Laod
for example:

myCombo1.Tag = Panel1;
myCombo2.Tag = Panel2;
myCombo3.Tag = Panel3;

在DropDown 组合事件中

In DropDown event of Comboes

HidePanels(); 
((Panel)(((ComboBox)sender)).Tag).Visible = true;
