从C#应用程序批量访问设置的变量 [英] Access variable set in batch from C# application

问题描述

我有一个批处理文件setEnv.bat.

@echo off
set input=C:\Program Files\Java\jdk1.8.0_131
SET MY_VAR=%input%

我想从C#应用程序运行此批处理文件，并想从c#应用程序访问新设置的MY_VAR值.

I want to run this batch file from C# application and want to access the newly set value of MY_VAR from c# application.

C#:

System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo.FileName= "D:\\Check\\SetJavaHome.bat";
proc.StartInfo.WorkingDirectory = 
System.Environment.CurrentDirectory;
proc.Start();

字符串myVar = Environment.GetEnvironmentVariable("MY_VAR");

string myVar = Environment.GetEnvironmentVariable("MY_VAR");

有人可以帮助我按预期工作吗?

Can someone help me in getting this working as expected?

谢谢.

不可能直接从另一个进程获取Environment变量，但是一个简单的解决方法可能是:

Getting the Environment variables directly from another process is not possible, but a simple workaround can be like:

创建一个虚拟蝙蝠文件(env.bat)，该文件将执行所需的bat并回显环境变量. 在C#的流程执行中获取此env.bat的输出.

Create a dummy bat file (env.bat) that will execute the required bat and echo the environment variable. Get the output of this env.bat inside the process execution of C#.
