How to detect which .NET runtime is being used (MS vs. Mono)?
提问by Dirk Vollmar
I would like to know during execution of a program whether it is being executed using the Mono runtime or the Microsoft runtime.
我想知道在程序执行期间它是使用 Mono 运行时还是 Microsoft 运行时执行的。
I'm currently using the following code to determine whether I'm on a MS CLR:
我目前正在使用以下代码来确定我是否在 MS CLR 上：
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.
但是，这在某种程度上取决于运行时的安装文件夹，我不确定这是否适用于所有安装。
Is there a better way to check for the current runtime?
有没有更好的方法来检查当前运行时？

From the Mono Project's Guide to Porting Winforms Applications:
从 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
我相信你会有更多的问题，所以值得查看本指南和单一论坛

You can check for the Mono Runtime Like this
您可以像这样检查 Mono 运行时
bool IsRunningOnMono = (Type.GetType ("Mono.Runtime") != null);

just run the below code..
只需运行下面的代码..
static bool IsMicrosoftCLR()
{
return (Type.GetType ("Mono.Runtime") == null)
}

With the advent of C# 6, this can now be turned into a get-only property, so the actual check is only done once.
随着 C# 6 的出现，这现在可以变成一个 get-only 属性，因此实际检查只执行一次。
internal static bool HasMono { get; } = Type.GetType("Mono.Runtime") != null;

Here's a version with caching that I'm using in my project:
这是我在项目中使用的带有缓存的版本：
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.
正如@ahmet alp balkan 所提到的，如果您经常调用它，缓存在这里很有用。通过将它包装在 a 中Lazy<bool>，反射调用只发生一次。
