c# - 如何从 .NET Core 中的流加载程序集

Question

我正在 .NET Core 控制台应用程序上体验 Roslyn。我试图创建一个程序集并将其编译成内存流。但是加载它似乎缺少一个 API ( that normally works on the regular .NET Framework )

var compilation = CSharpCompilation.Create("MyCompilation",
         syntaxTrees: new[] { pocoTree }, references: new[] { mscorlib, currentAssembly });

var ms = new MemoryStream();
var emitResult = compilation.Emit(ms);

var ourAssembly = Assembly.Load(ms.ToArray()); // Fails to compile here

我收到这个错误:

cannot convert from 'byte[]' to 'System.Reflection.AssemblyName'

.NET Core 中从 Steam 加载的替代方法是什么？ (除了物理保存程序集并加载它)

您可以使用 AssemblyLoadContext 从 .NET core 中的流加载程序集:

// requires "System.Runtime.Loader": "4.0.0",
protected virtual Assembly LoadAssembly(MemoryStream peStream, MemoryStream pdbStream)
{
    return System.Runtime.Loader.AssemblyLoadContext.Default.LoadFromStream(peStream, pdbStream);
}
