C＃新建过程中产生的不能访问某些文件 [英] C# New process created cannot access certain files

问题描述

我创建了C＃的过程（比如CMD.EXE）。但是，所创建的exe不能够访问所有的文件由用户运行的方法。

I created a process in C# (say cmd.exe). But, the created exe is not able to access all of the files as a process run by the user.

我已经清楚地嵌入屏幕画面说明了这个问题。其中我的应用程序创建的进程（CMD）是在左侧，一个在右侧打开直接与运行命令。我已经做了DIR CMD在这两个命令提示符中运行。在计数的差异大大惊人的我。

The screenshot which I have embedded clearly illustrates this issue. The process (cmd) which my application created is in the left side and the one in right side is opened with a run command directly. I have made a dir cmd to execute on both of these command prompts. The difference in the count is greatly astonishing me.

对不起它喊，我没有足够的声誉。截图的所以才的链接。

Sorry it shouts that I don't have enough reputation. So just the link of the screenshot.

该截图显示

我认为有关应用程序的高度，因为我认为这个过程是不允许访问的所有文件该系统为标准用户。所以我提升的过程。

I considered about the elevation of the application, because I thought that the process was not allowed to access all the files of the system to a standard user. So I elevated the process.

在我的计划，我试图创建一个cmd提示符并执行java命令由它来运行jar文件。

In my program, I tried to create a cmd prompt and execute the java command from it to run a jar file.

也不要问有关PATH变量（等等，等等，等等）。由于java.exe的掌握在system32 /文件夹这已经是在PATH变量。

Also don't ask about the PATH variables (blah, blah, blah). Because the java.exe rests in the system32/ folder which is already in the PATH variable.

下面是创建新进程的函数的源代码。

The following is the source code of a function that creates the new process.

Process process = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo(@"C:\Windows\System32\cmd.exe");
startInfo.UseShellExecute = true;
startInfo.Verb = "runas";
startInfo.Arguments = "/C java.exe";
process.StartInfo = startInfo;
process.Start();

不久，

• x是用的Process.Start

创建新进程
• x不能找到其中通常应用程序查找一个文件。

X得到管理员权限也

• x是颇为神秘??

• x is a new process created with Process.start
• x can't find a file which an usual app finds.
• x got admin rights also
• x is quite mysterious??

修改

• 假设x是一个cmd.exe的，它打开C：/中/ Windows的Syswow64资料代替预计C：/在Windows / System32下运行命令 CD C：/在Windows / System32下/


• 我如何访问的实际System32下文件夹？

推荐答案

看一下文件大小，他们也不同，实际上文件夹是不一样的。右边是C：\windows\system32而左边C：\Windows\SysWOW64

Look at the file sizes, they are also different, and actually the folders are not the same. On the right is C:\windows\system32 while on the left C:\Windows\SysWOW64

似乎是位数的问题。通过Windows任务管理器中查看你的流程的位数。左侧的人都应该有* 32旁边。它运行作为32位进程，默认情况下是在SysWow64文件夹

Seems to be a matter of bitness. Check by the windows task manager the bitness of your processes. The one on the left should have *32 next to it. It runs as an 32 bit process and by default is in SysWow64 folder

请注意：OP再改目标平台到x64其解决了问题。

Note: OP then changed the target platform to x64 which solved the issue
