VB.NET Get Only Year from Date
提问by Dave Mackey
I'm pulling into a variable a datetime value. Now, I want to post this value back to my database, but I need it to be only the year digits. How do I get VB.NET to trim the month, day, and time off and just return the four character year (e.g. 2011)?
我正在拉入一个变量日期时间值。现在，我想将此值发布回我的数据库，但我只需要它是年份数字。如何让 VB.NET 修剪月、日和时间并只返回四个字符的年份（例如 2011）？

Date.Today.Yearis what you're looking for, or for an existing date, just someDateVariable.Year
Date.Today.Year是您正在寻找的，或现有的日期，只是 someDateVariable.Year

Dim myDate As DateTime = #1/1/2011#
Dim myYear As Int32 = myDate.Year

There is a property on the DateTime structure called 'Year'. This returns an integer representing just the year.
DateTime 结构上有一个名为“Year”的属性。这将返回一个仅代表年份的整数。
If you need to convert this to a string, just use the ToString() function.
如果您需要将其转换为字符串，只需使用 ToString() 函数。
So..
所以..
MyDT.Year.ToString()
That's a c# example, I'm sure VB.Net is going to be very similar.
这是 ac# 示例，我确信 VB.Net 将非常相似。

i know this is a bit late to answer but, it wont hurt telling, try "year(now) " and load it to a variable Example:
我知道回答有点晚了，但是，说出来不会有什么坏处，请尝试“year(now)”并将其加载到变量中 示例：
Dim Year_in_Digits = Year(Now)

I just had to do this for my VB program.
我只需要为我的 VB 程序执行此操作。
Dim Year As Integer
Year = Convert.ToInt32(Now.ToString("yyyy"))
Use just "yy"if you want two digit year. Then, when you need to display it somewhere:
只使用"yy"如果你希望两个数字的年份。然后，当您需要在某处显示它时：
year.tostring
