{
protected void Page_Load(object sender, EventArgs e)
{ this.Label1.Text = this.DropDownList1.SelectedValue; this.Label2.Text = this.DropDownList2.SelectedValue;
} protected void Button1_Click(object sender, EventArgs e) { if (this.Label3.Text == "我是A！") { this.Label3.Text = "我是B，我怎么来这了？"; } else { this.Label3.Text = "我是A！"; } } protected void Button2_Click(object sender, EventArgs e) { if (this.Label4.Text == "我是B！") { this.Label4.Text = "我是A，我怎么来这儿了？"; } else { this.Label4.Text = "我是B！"; } }
