在C#中设置环境变量，该变量在执行完成后仍然存在 [英] Setting Environment variables in C# that persist after execution is complete

问题描述

我需要从C#程序中设置环境变量，以便稍后运行的批处理文件可以使用此新创建的变量.我尝试使用:

I need to setup an environment variable from a C# program so batch files that run later can use this newly created variable. I have tried using:

Environment.SetEnvironmentVariable("USRNAM", "My Name", 
                                    EnvironmentVariableTarget.Process);

在此语句之后，我设置了一个断点，当它到达该断点时，我转到命令提示符，发出以下命令:

After this statement I have a breakpoint setup and when it gets to this breakpoint, I go to a Command Prompt, issue the following command:

C:\Users\Lenovo>SET USRNAM

我得到:

Environment variable USRNAM not defined.

如何设置在C#程序执行完成后仍然存在的环境变量?

How can I set an Environment variable that persists after the C# program execution has completed?

非常感谢您的建议.

推荐答案

尝试使用 EnvironmentVariableTarget.User 或 EnvironmentVariableTarget.Machine ，具体取决于您是否愿意为当前用户或所有用户创建的变量.

Try to use either EnvironmentVariableTarget.User or EnvironmentVariableTarget.Machine, depending on whether you'd like the variable to be created for the current user or for all users.

在此处中查找有关该枚举的信息.
