替换 Net Core 中的 AppDomain

Question

所以，我是 C# 和 Net Core 的新手，有人将代码传递给了评估命令。 但是不是Net Core做的，所以Net Core中不存在AppDomain，怎么办？

ScriptOptions so = ScriptOptions.Default;

            so = so.WithImports(new string[] { "System.Math", "System.Diagnostics", "System.Runtime.InteropServices",
            "Discord.WebSocket", "Discord.Commands", "Discord", "System.Threading.Tasks", "System.Linq", "System", "System.Collections.Generic", "System.Convert", "System.Reflection"});
            so = so.WithReferences(AppDomain.CurrentDomain.GetAssemblies().Where(xa => !xa.IsDynamic && !string.IsNullOrWhiteSpace(xa.Location)));

Answer 1

.net 核心中没有AppDoamain，您可以使用Microsoft.Extensions.DependencyModel 库来实现您所需要的。

下面是来自article 的代码。您可以在那里查看完整的详细信息。

return GetReferencingLibraries("Specify")
.SelectMany(assembly => assembly.ExportedTypes);

public static IEnumerable<Assembly> GetReferencingAssemblies(string assemblyName)
{
    var assemblies = new List<Assembly>();
    var dependencies = DependencyContext.Default.RuntimeLibraries;
    foreach (var library in dependencies)
    {
        if (IsCandidateLibrary(library, assemblyName))
        {
            var assembly = Assembly.Load(new AssemblyName(library.Name));
            assemblies.Add(assembly);
        }
    }
    return assemblies;
}

private static bool IsCandidateLibrary(RuntimeLibrary library, assemblyName)
{
    return library.Name == (assemblyName)
        || library.Dependencies.Any(d => d.Name.StartsWith(assemblyName));
}

您需要包含Microsoft.Extensions.DependencyModel 包才能使用上述代码。
