I want to show each item Id that is doing now dynamically in a foreach statement.

But the following code only shows the last item Id in Label1.Text.

How to show Label1.Text for each item in a foreach statement?

I use asp.net C#.

protected void Button1_Click(object sender, EventArgs e)
    {
        List<int> list = new List<int>()
        {
            1,2,3,4,5
        };

        foreach (var item in list)
        {
            Label1.Text = string.Format("I'm doing item {0} now.", item.ToString());
            Thread.Sleep(1 * 1000);
        }
    }
