如何在 C# 中获取有关当前运行时的信息？

Question

在 C# 程序中，我需要获取有关程序所在的运行时环境的信息运行。

本质上，我需要知道当前程序是运行 in .NET Core 还是 Full .NET Framework 4.x。

类似以下的方法可能有效：

public string GetRuntimeVersion()
{
 #if NET451
    return "net451";
 #elseif netcoreapp11
    return "netcoreapp11"; 
 #elseif netstandard14
    return "netcoreapp14";
 #endif
...
}

但是有没有更好的方法呢？

Answer 1

勾选 System.Environment.Version 属性 (http://msdn.microsoft.com/en-us/library/system.environment.version.aspx).

public static void Main()
{
    Console.WriteLine("Version: {0}", Environment.Version.ToString());
}

Answer 2

Microsoft.Extensions.PlatformAbstractions !

using Microsoft.Extensions.PlatformAbstractions;

var runtimeInfo = PlatformServices.Default.Application.RuntimeFramework;

PlatformServices.Default.Application.RuntimeFramework 属性包含运行时标识符及其版本等信息。并且在 .net 核心上可用。

现在好像还有System.Runtime.InteropServices.RuntimeInformation。

PROPERTIES FrameworkDescription
Gets the name of the .NET installation on which an app is running.

OSArchitecture
Gets the platform architecture on which the current app is running.

OSDescription Gets a string that describes the operating system on which the app is running.

ProcessArchitecture
Gets the process architecture of the currently running app.

RuntimeIdentifier Gets the platform on which an app is running.

https://docs.microsoft.com/en-us/dotnet/api/system.runtime.interopservices.runtimeinformation?view=net-6.0

using System;
                    
public class Program
{
    public static void Main()
    {
        Console.WriteLine(System.Runtime.InteropServices.RuntimeInformation.FrameworkDescription);
        Console.WriteLine(System.Runtime.InteropServices.RuntimeInformation.OSArchitecture);
        Console.WriteLine(System.Runtime.InteropServices.RuntimeInformation.OSDescription);
        Console.WriteLine(System.Runtime.InteropServices.RuntimeInformation.ProcessArchitecture);
        Console.WriteLine(System.Runtime.InteropServices.RuntimeInformation.RuntimeIdentifier);
    }
}

有趣的是，这在 powershell 中似乎不起作用，至少在尝试运行时对我来说不起作用：[System.Runtime.InteropServices.RuntimeInformation]::RuntimeIdentifier
