Visual Studio Code – Detect specific word or pattern in source code files in Visual Studio?

I want to detect specific word or pattern in the all source code files. For ex. if I want to restrict DateTime.Now to be used in the project but if some team member has used this in the source code, I want to fail build operation.

I don’t know what is the proper way to do it but can I use VS Pre-Build event for the same? If no then can someone guide me on the correct path to fulfill my requirement?

    It’s a manual approach but could you do like global search by using Ctrl+Shift+F
    and put your regex or as in your example DateTime.Now in the search bar and alter whatever the things you need

    You can execute PowerShell scripts by entering a command like PowerShell MyPowerShellScript.ps1 in PreBuildEvent.The scripts include searching specific word or pattern in the all source code files.

    Please follow the steps below.(example)

    1. Powershell script
    $results = Get-ChildItem -Path {your project path} -Recurse | Select-String -Pattern "DateTime.Now";
if([string]::IsNullOrEmpty($results)){
  Write-Host "not found specific word DateTime.Now"
}else{
  Write-Host " found specific word DateTime.Now"
  #other than zero (0)
  exit 1
}

    Note:

    Have your event action exit with a code other than zero (0). A zero exit code indicates a successful action; any other exit code is considered an error.

    2.Enter a command like PowerShell MyPowerShellScript.ps1.
    On the Project menu->click {ProjectName} Properties (or from Solution Explorer, press Alt+Enter)->Select Build > Events.
    enter image description here

    Visual Studio modifies your project file by adding the PreBuildtarget and the necessary MSBuild code to execute the steps you provided.

    <Target Name="PreBuild" BeforeTargets="PreBuildEvent">
  <Exec Command="PowerShell {your project path}pw.ps1" />
</Target>

    3.Build the project and watch the output window. If it finds the specific world(DateTime.Now) in your source code files, the script exits with code 1 and the build fails.

    Hope it can help you.
