如何检测正在使用哪个 .NET 运行时（MS 与 Mono）？

Question

I would like to know during execution of a program whether it is being executed using the Mono runtime or the Microsoft runtime.

I'm currently using the following code to determine whether I'm on a MS CLR:

static bool IsMicrosoftCLR()
{
    return RuntimeEnvironment.GetRuntimeDirectory().Contains("Microsoft");
}

However, this is somewhat dependent on the installation folder of the runtime and I'm not sure whether this will work on all installations.

Is there a better way to check for the current runtime?

Answer 1

From the Mono Project's Guide to Porting Winforms Applications :

public static bool IsRunningOnMono ()
{
    return Type.GetType ("Mono.Runtime") != null;
}

I'm sure you'll have a lot more questions, so worth checking this guide and the mono-forums

Answer 2

您可以像这样检查 Mono 运行时

bool IsRunningOnMono = (Type.GetType ("Mono.Runtime") != null);

Answer 3

随着 C# 6 的出现，现在可以将其转换为仅获取属性，因此实际检查只进行一次。

internal static bool HasMono { get; } = Type.GetType("Mono.Runtime") != null;

Answer 4

Here's a version with caching that I'm using in my project:

public static class PlatformHelper
{
    private static readonly Lazy<bool> IsRunningOnMonoValue = new Lazy<bool>(() =>
    {
        return Type.GetType("Mono.Runtime") != null;
    });

    public static bool IsRunningOnMono()
    {
        return IsRunningOnMonoValue.Value;
    }
}

As @ahmet alp balkan mentioned, caching is useful here if you're calling this frequently. By wrapping it in a Lazy<bool> , the reflection call only happens once.

Answer 5

just run the below code..

static bool IsMicrosoftCLR()
{
    return (Type.GetType ("Mono.Runtime") == null)
}

System.Runtime.InteropServices.RuntimeInformation.FrameworkDescription提供运行应用程序的 .NET 安装的名称和版本，例如“单声道版本”
