Getting specific days in a month

I’ve touched on this problem once before, in How to find the 3rd Friday in a month with C#? But since I did not explain my problem well then, I must try again:

My goal here is simple: upon the press of a button (referred to here as “Button1”), I must determine whether today’s date is prior to either the first, or the third Wednesday of the month. If this is the case, I must then set the text of a label (referred to here as “lblDate”) to the date of whichever of these future Wednesdays is nearest to the current date.

So far, I’ve written this:

protected void Button1_Click(object sender, EventArgs e)
{

    DateTime Now = DateTime.Today;
    DateTime TempDate = new DateTime(Now.Year, Now.Month, 1);

    if (TempDate.DayOfWeek != DayOfWeek.Wednesday)
    {
        TempDate = TempDate.AddDays(1);
        string date = TempDate.ToString();
        lblDate.Text = date;
    }
    if (TempDate == TempDate.AddDays(1))
    {
        TempDate = TempDate.AddDays(14);
        string date = TempDate.ToString();
        lblDate.Text = date;
    }

}

As you can see, something is missing. I would greatly appreciate any assistance in filling that in…

You could also try it like this:

protected DateTime getFirstWednesdayOfMonth(DateTime seedDate)
{
    DateTime wed1 = new DateTime(seedDate.Year, seedDate.Month, 1); //1st Wednesday can start on the 1st of the month
    while (wed1.DayOfWeek != DayOfWeek.Wednesday)
    {
        wed1 = wed1.AddDays(1);
    }
    return wed1;
}

protected DateTime getThirdWednesdayOfMonth(DateTime seedDate)
{
    DateTime wed3 = new DateTime(seedDate.Year, seedDate.Month, 15); //3rd Wednesday cannot start prior to the 15th of the month
    while (wed3.DayOfWeek != DayOfWeek.Wednesday)
    {
        wed3 = wed3.AddDays(1);
    }
    return wed3;
}
protected void Button1_Click(object sender, EventArgs e)
{
    DateTime Now = DateTime.Today;
    DateTime wed1 = getFirstWednesdayOfMonth(Now);
    DateTime wed3 = getThirdWednesdayOfMonth(Now);

    if (Now < wed1)
    {
        lblDate.Text = wed1.ToString();
    }
    else if (Now < wed3)
    {
        lblDate.Text = wed3.ToString();
    }
}
