如果经过特定天数，则触发操作VB.NET [英] Trigger Action if a specific amount of days is gone VB.NET

问题描述

下面的代码已经可以使用了，但是仅适用于Filesystem.FileDateTime，为此我需要一个文件，但是当我用日期字符串替换它时，即使我发现filedatetime的datemethod与其相同，也无法使用我写Now.ToString时将返回.

WORKS;

This code below works already, but only with Filesystem.FileDateTime, and for this i need a file, but it doesnt work when i replace it with a date string even i found out that the datemethod of filedatetime the same is as it will be returned when i write Now.ToString.

WORKS;

If DateDiff("d", FileSystem.FileDateTime("C:\example.ini"), Now) > 15 Then
MsgBox("The Free Version reached the Free Limit of 15 Days") : Else : End If

不工作；

DOESNT WORK;

If DateDiff("d", 1.5.2012 12.00.00MD, Now) > 15 Then
MsgBox(""): Else : End If

我是否必须将其声明为日期或字符串，还是想念其他东西?
这是非常困难的，因为要证明正确的解决方案，我必须至少等待一天.提前谢谢！

已添加代码标签-LOSMAC [/EDIT]

Do i have to declare it as date or as string or did i miss something else?
This is very difficult since to prove the right solution i must wait at least one day. Thanks in advance!

推荐答案

是的，您必须先创建日期，然后执行DateDiff.
像这样的东西.

Yes, you have to create date and then do DateDiff.
Some thing like this.

If DateDiff("d", new System.DateTime(2012,5,1,12,0,0), Now) > 15 Then
MsgBox(""): Else : End If

DateDiff需要2个日期是DateTime. 1.5.2012 12.00.00MD不是DateTime，因此将其转换为1并使用它.

DateDiff requires the 2 dates to be DateTime. 1.5.2012 12.00.00MD is not a DateTime, so convert it to one and use it.
