从内存加载程序集

我正在移植一个 Java 应用程序，其中类在运行时从内存（字节数组）加载并“执行”。我试图在 C# 中实现同样的目标，但在尝试从字节数组加载程序集（使用 AppDomain.Load ）时遇到问题（System.IO.FileNotFoundException 异常）代码>方法）。

static void Main(string[] args)
{
    var domain = AppDomain.CreateDomain("foo");

    domain.AssemblyResolve += new ResolveEventHandler(domain_AssemblyResolve);

    var assembly = domain.Load("MyAssembly");
}
static Assembly  domain_AssemblyResolve(object sender, ResolveEventArgs args)
{
    // ...
    return Assembly.ReflectionOnlyLoad(File.ReadAllBytes(@"C:\MyAssembly.exe"));
}

有没有办法加载它们而不需要将此字节数组保存到文件系统中？

简化一下想法，我们希望具有动态执行和更改（更新）代码的能力。我们使用单独的应用程序域来“加载/卸载”程序集。

I am porting a Java application where classes are loaded and "executed" at runtime from memory (a byte array). I am trying to achieve the same thing in C#, but I am having problems (System.IO.FileNotFoundException exceptions) when trying to load assemblies from byte arrays (using the AppDomain.Load method).

static void Main(string[] args)
{
    var domain = AppDomain.CreateDomain("foo");

    domain.AssemblyResolve += new ResolveEventHandler(domain_AssemblyResolve);

    var assembly = domain.Load("MyAssembly");
}
static Assembly  domain_AssemblyResolve(object sender, ResolveEventArgs args)
{
    // ...
    return Assembly.ReflectionOnlyLoad(File.ReadAllBytes(@"C:\MyAssembly.exe"));
}

Is there a way to load them without the need to persist this byte array into the file system?

Simplifying the idea, we want to have the ability to execute and change (update) code dynamically. We use separate application domains to "load/unload" assemblies.

我刚刚尝试过这段代码：

static void Main(string[] args)
        {

            var h = File.ReadAllBytes(@"C:\MyAssembly.exe");

            var g = Assembly.Load(h);            
        }

它运行良好 - 我没有遇到任何异常。您是否 100% 确定目标程序集存在？

I've just tried this code:

static void Main(string[] args)
        {

            var h = File.ReadAllBytes(@"C:\MyAssembly.exe");

            var g = Assembly.Load(h);            
        }

and it worked fine - I did not get any exceptions. Are you 100% sure that the target assembly exists?
