存在存在ExitCode 255的进程 [英] Process exists with ExitCode 255

问题描述

[IIS 7.5/Windows 7/Visual Studio 2012]

[IIS 7.5 / Windows 7 / Visual Studio 2012]

我试图让我的MVC应用程序运行位于同一台计算机上的外部命令行工具.

I am trying to have my MVC app run an external command line tool located on the same machine.

我将IIS_USRS的执行权限授予了包含该工具的整个文件夹.

I gave execute permissions to IIS_USRS to the whole folder that contains the tool.

我通过以下方式调用它:

I invoke it with:

ProcessStartInfo startInfo = new ProcessStartInfo();  
startInfo.WindowStyle = ProcessWindowStyle.Normal;  
startInfo.FileName = myPath;  
startInfo.Arguments = myArguments;  
PartialRunProcess = Process.Start(startInfo);  

没有例外(路径正确)，但是该过程立即存在，退出代码为255

No exceptions (path is right), but the process exists rightaway with ExitCode 255

我可以手动执行该过程.

I can execute the process manually.

可能是什么原因?

推荐答案

退出代码255听起来像您正在运行的工具(目标应用程序)中的.NET异常.您将无法在代码中捕获此异常.

Exit code 255 sounds like a .NET exception within the tool (target application) you're running. You'll not be able to catch this exception in your code.

我会注册调试器目标应用程序以查看它引发了什么异常:

I would register a debugger for the target application to see what exception it throws:

1. 转到 HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Image文件执行选项

使用您要启动的可执行文件的名称创建一个密钥

Create a key with the name of the executable you're starting

创建一个名为 Debugger

为其提供一个值，例如 vsjitdebugger.exe (如果它是.NET应用程序)

Give it a value, e.g. vsjitdebugger.exe if it's a .NET application

这将启动调试器，您可以捕获异常.

This will start the debugger and you can catch exceptions.
