asp.net+access 怎么在。cs页面里判断 “随便写个时间” 是否是本周？

Answer 1

  public static bool IsThisWeek(DateTime someDate)
        {
            DateTime dt = DateTime.Now;            DateTime nowMon = dt.AddDays(1 - Convert.ToInt32(dt.DayOfWeek.ToString("d"))); 
            
            TimeSpan ts = someDate - nowMon;            if (ts.Days >= 0 && ts.Days < 7)
            {
                return true;
            }
            else
            {
                return false;
            }
        }

Answer 2

static bool isInCurrentWeekday(DateTime dt)
        {
            DateTime now = DateTime.Now;
            int st = now.Day - Convert.ToInt32(now.DayOfWeek.ToString("d")) + 1;
            if (dt.Day >= st && dt.Day <= st + 7)
            {
                return true;
            }
            return false;
        }

我去写了下，方法有点笨，不过测试通过！
期待更好的办法<div>
        <asp:TextBox ID="txtDateTime" runat="server"></asp:TextBox><asp:RequiredFieldValidator
            ID="valdDateTime" runat="server" ErrorMessage="不能为空" 
            ControlToValidate="txtDateTime" Display="Dynamic" Font-Size="12px"></asp:RequiredFieldValidator><asp:RegularExpressionValidator
                ID="valeDateTime" runat="server" ErrorMessage="时间不合法" 
            ControlToValidate="txtDateTime" Display="Dynamic" Font-Size="12px"

        <asp:Button ID="btnSumbit" runat="server" Text="验证" onclick="btnSumbit_Click" />
        <asp:Label ID="lblMessage" runat="server"></asp:Label>
    </div>先验证时间不能空，而且为合法的时间格式protected void btnSumbit_Click(object sender, EventArgs e)
        {
            DateTime checkTime;
            DateTime dtNow = DateTime.Now;  //当前时间
            DateTime startWeek;
            DateTime endWeek;            //如果验证通过
            if (IsValid)
            {
                checkTime = Convert.ToDateTime(txtDateTime.Text); //用户输入的时间
                startWeek = Convert.ToDateTime(dtNow.AddDays(1 - Convert.ToInt32(dtNow.DayOfWeek.ToString("d"))).ToString("yyyy-MM-dd 00:00:00")); //本周周一
                endWeek = Convert.ToDateTime(startWeek.AddDays(6).ToString("yyyy-MM-dd 23:59:59"));  //本周周日
                if (checkTime >= startWeek && checkTime <= endWeek)
                {
                    lblMessage.Text = "时间是在本周内";
                }
                else
                {
                    lblMessage.Text = "时间不是在本周内";   
                }
            }
        }
