Question

使用VB.NET确定当前时间是AM还是PM的最佳方法是什么？

目前我正在使用If Date.Today.ToString.Contains（“AM”），但我确信有更好的方法。

Good <%If Date.Today.ToString.Contains("AM") Then Response.Write("Morning") Else Response.Write("Afternoon")%>

Answer 1

If Date.Now.Hour < 12 Then ...也许？

Answer 2

Now.ToString("t") == "A" //or //"P"

Answer 3

这个怎么样：

Now.Hour > 17 ' Night
Now.Hour < 5  ' Day

HTH

Answer 4

下午检查需要＆lt; =否则在17小时设置

dim hours as int = DateTime.Now.Hour
dim str as string
if hours < 12 Then
    str = "Morning"
else if hours <= 17 then
    str = "Afternoon"
else if hours > 17 then
    str = "Evening"
End If

Answer 5

这个怎么样：

dim hours as int = DateTime.Now.Hour
dim str as string
if hours < 12 Then
    str = "Morning"
else if hours < 17 then
    str = "Afternoon"
else if hours > 17 then
    str = "Evening"
End If

Answer 6

Private Function IsMidnight(ByVal value As DateTime) As Boolean
    Return value.Hour = 0 And _
        value.Minute = 0 And _
        value.Second = 0 And _
        value.Millisecond = 0
End Function

用法：

Dim isAM as Boolean = (IsMidnight(current) Or current.Hour < 12)

确定当前时间是AM还是PM的最简单方法？
