无法从C＃执行“ cmd”或批处理文件

Question

i need to run a batch file (or a cmd) from c# . my code is this simple:

 Process.Start(@"C:\b.bat");
Process.Start(@"cmd.exe");

i have also tried Executing Batch File in C# , and many other sites but i do not think the problem is syntax related.

the error happens for either line above, which I have googled but not found a solution for my particular problem:

An unhandled exception of type 'System.ComponentModel.Win32Exception' occurred in System.dll Additional information: The specified executable is not a valid application for this OS platform.

the weird thing is that these codes will run no problem:

Process.Start(@"IExplore.exe");
Process.Start("notepad");

i am running visual studio 2012 and compiling for x86, but my OS is windows 7 64-bit ,not sure if it matters.everything else in the program runs fine.

any help would be greatly appreciated!

Answer 1

I think your problem is that you are trying to start an unknown process in Process.Start(@"C:\\b.bat") . When I do this i use the following.

        string cmd = "/C b.bat";
        var m_command = new System.Diagnostics.Process();
        m_command.StartInfo.FileName = @"cmd.exe";
        m_command.StartInfo.Arguments = cmd;
        m_command.Start();

The /C will close the applciation after it is finished. So in essence the above code will:

1. Start the cmd.exe process
2. Execute your arguments (in this case /C b.bat )
3. You can also add m_command.WaitForExit() if you want to have the program wait for b.bat to finish executing before continuing.

Answer 2

Process.Start(@"C:\\b.bat"); ought to work, but putting it into the root may be causing the problem. Try moving the bat file to your project directory, and put the absolute path to the file. For example, I just had success with Process.Start(@"""C:\\dev\\ConsoleApplication1\\ConsoleApplication1\\test.bat""");

Answer 3

I solved the problem by running the 32 bit cmd with this command:

proc.StartInfo.FileName = @"C:\\windows\\system32\\cmd.exe";
