用于标记输出 C# 的下拉列表

我想显示从 DropDownList 输出的不同标签

select Item on DropDownList and click button to show output in label

谁能帮我解决这个问题？

用于标记输出 C# 的下拉列表

protected void Button1_Click(object sender, EventArgs e)
{
       Label1.Text = DropDownList1.SelectedValue;
}

只需将其写在button click event

protected void Button1_Click(object sender, EventArgs e) { 
    label.text = ComboBox.SelectedText;
}

protected void Button1_Click(object sender, EventArgs e)
{
    lable1.Text=DropDownList1.SelectedValue.ToString();
}

或者你可以做

   protected void Button1_Click(object sender, EventArgs e)
   {
       String input=DropDownList1.SelectedIndex >= 0 ? DropDownList1.SelectedItem.ToString() : "";
       lable1.Text=input;
   }
