Where Is Machine.Config?

问题:

I want to apply a change so That I can use Server GC settings for my C# 3.5 app - I can do that by editing the machine.config file.

The only problem is I do not know where that is.

How can I find the path of this file in a repeatable way across a number of different machines

回答1:

32-bit

%windir%\\Microsoft.NET\\Framework\\[version]\\config\\machine.config

64-bit

%windir%\\Microsoft.NET\\Framework64\\[version]\\config\\machine.config 

[version] should be equal to v1.0.3705, v1.1.4322, v2.0.50727 or v4.0.30319.

v3.0 and v3.5 just contain additional assemblies to v2.0.50727 so there should be no config\\machine.config. v4.5.x and v4.6.x are stored inside v4.0.30319.

You can run this in powershell:

[System.Runtime.InteropServices.RuntimeEnvironment]::SystemConfigurationFile

Which outputs this for .net 4:

C:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319\\config\\machine.config

Note however that this might change depending on whether .net is running as 32 or 64 bit which will result in \\Framework\\ or \\Framework64\\ respectively.

In order to be absolutely sure, slap a Label on an ASP.NET page and run this code:

labelDebug.Text = System.Runtime.InteropServices.RuntimeEnvironment.SystemConfigurationFile;

I believe this will leave no doubt!

回答4:

It semi-depends though... mine is:

C:\\Windows\\Microsoft.NET\\Framework\\v2.0.50727\\CONFIG

and

C:\\Windows\\Microsoft.NET\\Framework64\\v2.0.50727\\CONFIG

回答5:

C:\\Windows\\Microsoft.NET\\Framework\\v2.0.50727\\CONFIG

回答6:

In your asp.net app use this

using System.Configuration;
Response.Write(ConfigurationManager.OpenMachineConfiguration().FilePath);

回答7:

You can run this in powershell: copy & paste in power shell [System.Runtime.InteropServices.RuntimeEnvironment]::SystemConfigurationFile

mine output is: C:\\Windows\\Microsoft.NET\\Framework\\v2.0.50527\\config\\machine.config

1. Open Windows Run command. Shortcut=> windows key + r
2. Type \"microsoft.net\" - MS .Net folder opens up
3. Open \"Framework\"/\"Framework64\" folder(based on your processor).
4. Select specific FW version folder e.g. \"v4.0.30319\"
5. Open config folder
6. Machine.config will be available there. Cheers.
