如何在构建后事件中定义当前系统日期 [英] How to define current system date in post build event

问题描述

我想将 .dll 复制到格式为test\Project_yyyy.mm.dd"的目标目录中其中 yyyy - 当前年份，mm - 当前月份，dd - 当前日期.当我在构建后事件中给出以下命令时，出现错误.

I want to copy .dlls into a target directory of format "test\Project_yyyy.mm.dd" Where yyyy - cuurent year, mm - current month, dd - current date. When I give the below command in my post build event, I am getting an error.

xcopy /Y "$(TargetDir)*.*" test\Project_$(Year:yyyy).$(Month).$(DayOfMonth)

我找不到任何定义当前日期的宏.有人可以帮我解决这个问题.

I could not find any macro which define current date. Can someone please help me on this.

推荐答案

您可以使用 MSBuild 属性函数 调用一些 .Net API.您可以使用 System.DateTime.Now 获取当前时间，然后获取年/月/日作为此对象的属性.

You can use MSBuild Property Functions to call some of the .Net API. You can use System.DateTime.Now to obtain current time, then fetch year/month/day as properties of this object.

这是执行此操作的代码:

Here is a code that does this:

<Project ToolsVersion="12.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <CurrentYear>$([System.DateTime]::Now.Year)</CurrentYear>
    <CurrentMonth>$([System.DateTime]::Now.Month)</CurrentMonth>
    <CurrentDay>$([System.DateTime]::Now.Day)</CurrentDay>
  </PropertyGroup>

  <Target Name="Print">
    <Message Text="Year: $(CurrentYear)" />
    <Message Text="Month: $(CurrentMonth)" />
    <Message Text="Day: $(CurrentDay)" />
  </Target>
</Project>
