如何从C＃应用程序运行C ++二进制代码

Question

I have a binary data from a c++ application that works. I want to run that specific binary code directly from my C# application.

I have this function that I got from internet:

    static void MemExe(byte[] buffer)
    {
        Assembly asm = Assembly.Load(buffer);

        if (asm.EntryPoint == null)
            throw new ApplicationException("No entry point found!");

        MethodInfo ePoint = asm.EntryPoint;
        object ins = asm.CreateInstance(ePoint.Name);
        ePoint.Invoke(ins, null);
    }

It it works well with C# binary code, but if I try to open a C++ binary code it crashes.

The exception right here:

Additional information: Could not load file or assembly '5154816 bytes loaded Test, Version = 1.0.0.0, Culture = neutral, PublicKeyToken = null' or one of its dependencies. It was made an attempt to load program with an incorrect format.

I guess it is something related to the header? I am no expert...

Is it possible to run c++ binary in the same way that the function MemEx runs C# binary?

Thanks.

Assembly.Load(...) will only load .NET binaries.

If you want to have access to the API of binary other than .NET, you would want to use P/Invoke signatures.

If you want to run an executable, use System.Diagnostics.Process.Start(...) .
