如何从内存运行下载的文件? [英] How To Run A Downloaded File From Memory?

问题描述

可能重复:
加载EXE文件并从中运行内存使用C#

我正在使用WebClient类从Web服务器下载.exe.有没有一种方法可以运行.exe而不先将其保存到磁盘?

I am using the WebClient class to download a .exe from a web server. Is there a way that I can run the .exe without saving it to disk first?

为了完整起见，让我向您展示我到目前为止所拥有的.

For the purpose of completeness let me show you what I have so far.

这是我用来开始下载的代码:

Here is the code I use to start the download:

WebClient webClient = new WebClient();
webClient.DownloadDataCompleted += new DownloadDataCompletedEventHandler(webClient_DownloadDataCompleted);
webClient.DownloadDataAsync(new Uri("http://www.somewebsite.com/calc.exe"));

在(webClient_DownloadDataCompleted)方法中，我只是从参数e中获取字节:

And in the (webClient_DownloadDataCompleted) method I simply grab the bytes from the parameter e:

private void webClient_DownloadDataCompleted(object sender, DownloadDataCompletedEventArgs e)
{
    Byte[] downloadedData = e.Result;
    // how to run this like a .exe?
}

谢谢.

推荐答案

如果您的 .exe 是.NET程序，则可以

If your .exe is a .NET program, you can load an assembly and run its entry point.

否则，虽然有很多方法可以实现，但我看不到临时保存文件的问题目录并从那里运行它，这样就省去了很多麻烦.

Otherwise, while there are ways to do it, I can't see the problem with saving a file in temporary directory and running it from there which is so much less painful.
