You can use Exists and ReadAllText to get the contents of a file.

  <Target Name="Build">  
    <PropertyGroup>
      <TheFile>C:\Windows\System32\notepad.exe</TheFile>
      <FileContents Condition="Exists($(TheFile))">$([System.IO.File]::ReadAllText('C:\\Windows\System32\notepad.exe'))</FileContents>
    </PropertyGroup>
    <Message Condition="'$(FileContents)' != ''" Text="The file is not empty $(FileContents)" />
  </Target>
