How to define current system date in post build event

问题

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)

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

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.

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>
