如何使用C#在内存中执行.NET控制台应用程序? [英] How to execute a .NET console-application in memory using C#?

问题描述

我想从我的C#程序中直接从内存中执行一个包含另一个.NET可执行文件(一个C#控制台应用程序)的byte []，而无需接触磁盘.

From my C# program, I am trying to execute a byte[] containing another .NET executable (a C# console-application) directly from memory and without touching disk.

我知道这里也有类似的问题，还有一些关于如何做到这一点的好文章:

I am aware that there are similar questions posted here and also some good articles about how to do it like this one:

http://www.codeproject.com/Articles/13897/Load-an-EXE-File-and-Run-It-from-Memory

但是，它们都遇到相同的问题，但是它们只能用于在内存中执行Windows Forms应用程序，但是当我尝试执行Console-Applications时，它是行不通的.示例:

However, they all run into the same problem, they work BUT only for executing Windows Forms applications in memory, but when I try to execute Console-Applications it doesn't work. Example:

byte[] FileBytes = File.ReadAllBytes("C:\\MyTestProgram.exe");   // just for testing purposes

Assembly a = Assembly.Load(FileBytes);
MethodInfo m = a.EntryPoint;
m.Invoke(a.CreateInstance(m.Name), null);

当"MyTestProgram.exe"是Windows窗体时，它会完美执行.但是，当"MyTestProgram.exe"是控制台应用程序时，它将返回以下错误:

And when 'MyTestProgram.exe' is a Windows Form, it executes perfectly. But when 'MyTestProgram.exe' is a Console Application, it returns the following error:

未处理的异常:System.Reflection.TargetParameterCountException:参数计数不匹配"

"Unhandled exception: System.Reflection.TargetParameterCountException: Parameter count mismatch"

请注意，控制台应用程序未接收任何参数，所以这很奇怪...

Please note that the console application doesn't receives any arguments, so this is strange...

任何帮助将不胜感激:)

Any help would be very much appreciated :)

推荐答案

主要方法是静态的，您无需传递 Invoke 实例.您必须这样称呼它:

Main method is static, you don't need to pass Invoke an instance. You have to call it like this:

 var parameters = m.GetParameters().Length == 0 ? null : new[] { new string[0] };
 m.Invoke(null, parameters);

此代码处理 Main()和 Main(string [] args)变体.
