C# 显示dropdownlist中选定项的标签中的值

我有一个scrpt，当我从dropdownlist中选择一个项目时，我想在回发后在标签中显示值。当我从dropdownlist中选择一个项目时，例如“Apple”，它将在标签中显示苹果的价格。如果我在标签的下拉列表中选择“橙色”，它将显示橙色的价格。你知道怎么做吗？谢谢

这是代码

删除AddItems（）；并将其添加到select_changed代码中

protected void DropDownListArtikulli_SelectedIndexChanged(object sender, EventArgs e)
{
    LabelCmimi.Text = DropDownListArtikulli.SelectedValue.ToString();
}

您的问题不清楚。您当前的代码有什么问题？它读回输入的值。您是否询问如何获取价格，因为您的问题不清楚。

protected void DropDownListArtikulli_SelectedIndexChanged(object sender, EventArgs e)
{
    LabelCmimi.Text = DropDownListArtikulli.SelectedValue.ToString();
}
