从 PowerShell 调用 exe 并获取有关成功或失败的反馈 [英] Invoke an exe from PowerShell and get feedback on success or failure

问题描述

如何在 PowerShell 中运行可执行文件并通过 if 语句确定它是成功还是失败?

How can I run an executable in PowerShell and through an if statement determine whether it succeeded or failed?

更具体地说，我试图让 devenv.exe 从 PowerShell 脚本构建解决方案，我需要知道它是成功还是失败.失败，我的意思是构建失败，我假设 devenv 正在向 shell 发送一些东西(可能在 stderr 流中?)

More specifically I'm trying to get devenv.exe to build a solution from a PowerShell script and I need to know whether it succeeded or failed. By failed, I mean that the build has failed and I'm assuming devenv is sending something out to the shell (possibly in the stderr stream?)

我尝试使用 &、Invoke-Expression 和 Invoke-Item 并设法让它们全部运行 exe.但我永远无法获得关于成功/失败的反馈.

I tried using &, Invoke-Expression and Invoke-Item and managed to get all of them to run the exe. But I was never able to get feedback on success / failures.

推荐答案

您是否尝试过使用 $LASTEXITCODE 变量?它将包含最后调用的 .exe 的退出代码.

Have you tried using the $LASTEXITCODE variable? It will contain the exit code of the last .exe that was invoked.
