Use System.DateTime.Today. Some additional notes:
使用System.DateTime.Today. 一些补充说明：
While you're only interested in the date, you still get a
System.DateTimeobject. That is, there still isa time portion in the returned value, but it's left blank (all zeroes).It's important to remember this when you compare dates. If you want to compare two dates, and you've fetched one date via
DateTime.Todayand another date viaDateTime.Now, then these two dates will not be equal — precisely because one has the time set and the other doesn't.In VB.NET, the
Datekeyword is equivalent to theSystem.DateTimetype. So you can write:Date.TodayP.S.:It just occurred to me that it might be a good idea to write
Date.Today, butDateTime.Now, in order to make it even more explicit that the former property only returns the date portion, while the latter returns both a date and time portion.
虽然您只对日期感兴趣，但您仍然会得到一个
System.DateTime对象。也就是说，仍然是在返回值的时间部分，但它的留空（全零）。在比较日期时记住这一点很重要。如果您想比较两个日期，并且您已经通过 获取了一个日期
DateTime.Today和另一个日期DateTime.Now，那么这两个日期将不相等 — 正是因为其中一个设置了时间而另一个没有。在 VB.NET 中，
Date关键字等效于System.DateTime类型。所以你可以写：Date.TodayPS：我突然想到写
Date.Today, but可能是个好主意DateTime.Now，为了更明确地说明前一个属性只返回日期部分，而后者同时返回日期和时间部分。

Try the DateTime.Todaymethod for just the current date.
尝试DateTime.Today仅针对当前日期的方法。
This returns a DateTimeobject, just like DateTime.Now, but it's time portion is always set to 0.
这将返回一个DateTime对象，就像DateTime.Now，但它的时间部分始终设置为 0。

Imports System -general declaration part
Private Sub Show_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim currentdate As System.DateTime
Dim currenttime As System.DateTime
Dim currentDateTime As System.DateTime
currentdate = DateAndTime.Today
currenttime = DateAndTime.TimeOfDay
currentDateTime = DateAndTime.Now
MsgBox(currentdate)
MsgBox(currenttime)
MsgBox(currentDateTime)

Much simpler this way
这种方式简单多了
Public Class Form1
Dim GDate As String
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
GDate = Today
End Sub
End Class

Whenever you will have to retrieve you will get it and can convert into again date format later also
每当您必须检索时，您都会得到它，并且可以稍后再次转换为日期格式
Dim dt1 As String = Today
Dim time1 As String = TimeOfDay
msgbox(dt1)
msgbox(time1)
