一些Process.Start命令不起作用

Question

I am working on visual studio 2012 with C# , but some of the commands are not working with visual studio.

I am trying to access

 Process.Start(Path.Combine(Environment.SystemDirectory, "msconfig.exe"));

some other similar commands are not working. where as these functions are working fine in visual studio 2010 on same machine. Please provide me some solution.

it is showing "Win32Exception ... the system cannot find the file specified"

Answer 1

Summarizing what I put in the comments - you're seeing the issue because you're running in a 32-bit process that is then subject to File System Redirection - your attempts to access the System directory get redirected to (by default) C:\\Windows\\SysWOW64.

This directory doesn't contain an msconfig.exe .

Visual Studio 2012, introduced a AnyCPU Prefer 32-bit option, and that is selected by default.

Best advice would be to switch your build platform to 64-bit , or uncheck Prefer 32-bit .

Answer 2

This is not beacuse of any security. As exception says file not found at disk. This is the problem with Visual Studio Project file configuration.

string path = Path.Combine(Environment.SystemDirectory, "msconfig.exe");
if(File.Exists(path))
  Process.Start(path);

I simply tried this using default configuration and found that the if check itself failed. In order to achieve this you will have to change the platform for project. By default the Visual Studio environment is taking x86 always even though you are running 64-bit OS and selecting Any CPU. Below are the settings for your program to work. Right click on project in Solution Explorer and Select Settings -> Build -> Plateform target -> Select x64.

Have a look on below image for visual representation of settings:
