如何在C#代码中判断当前C#的版本和dotnet版本

代码如下：

using System.Reflection;
using System.Runtime.InteropServices;var csharpVersion = typeof(string).Assembly.GetCustomAttributes(typeof(AssemblyFileVersionAttribute), false).OfType<AssemblyFileVersionAttribute>().FirstOrDefault()?.Version;
Console.WriteLine($"C# Language Version: {csharpVersion}");var runtimeVersion = RuntimeInformation.FrameworkDescription;
Console.WriteLine($".NET Runtime Version: {runtimeVersion}");
