我想把Python代码注入到一个进程中,当它注入时,它似乎会使我的进程崩溃。我没有在我自己的程序中得到任何错误,但目标进程停止工作。被调用的非托管api没有给我任何错误,并且似乎已经正确地执行了它们的执行。在

如您所见,我已经将非托管API的返回值保存到变量中,这些变量用于查看它是否正常工作,它似乎运行良好,但它会导致目标进程崩溃,日志中没有记录任何与之相关的错误。 托管程序能否注入非托管进程?我投错变量类型了吗?外壳代码是否被错误地转换成字节数组?请告诉我,谢谢。在
编辑:它在CreateRemoteThread崩溃
CreateRemoteThread
在另一个进程中创建本机线程,它接收到的起始地址必须指向有效的计算机代码,否则该线程将使进程崩溃。在您描述的场景不同,您需要指示另一个进程的Python解释器执行一些代码。这是可以做到的,但这是不同的,难度要大得多。在
将本机库注入到另一个进程中,该进程执行两项操作:
使用IPC将要执行的Python代码发送到另一个进程,注入的库中的代码然后使用Python解释器执行该代码。在
您可以找到一个如何将DLL注入另一个进程in this Codeproject article的示例。在
看起来您正试图从.net运行一些任意的Python代码。现在您正试图调用Python解释器来实际执行此操作。在
这样做的坏处是:-在
现在解决这个问题的一种方法是直接在.net中调用python程序。现在我从来没有这样做过,我也从来没有在我的生活中见过Python(可能除了那种嘶嘶作响的类型)。看一看http://msdn.microsoft.com/en-us/library/ee461504.aspx,不幸的是他们把python存储在一个文件中并在那里调用它。不过,我确信您可以调用存储为字符串的代码。在
使用python的DLR实现的主要缺点是依赖第三方来正确地进行python->;CLR转换。但我认为IronPython是微软赞助的开源项目。在
