How to launch an external process in C#, using a cmd window

I am having trouble executing an external console application using Process.Start

Process p = new Process();
p.StartInfo.WorkingDirectory = "dump";
p.StartInfo.FileName = "test.exe";
p.StartInfo.Arguments = s;
p.Start();

When the argument that p generates executes, the external app开发者_StackOverflow中文版lication crashes, although if I copy the exact same argument in a command line window it runs fine.

So my question instead how would I create a new instance of a command window and then add the command test.exe + s to run?

So effectively I am launching cmd and then adding my arguments on to it

If you want to run test.exe prm1 prm2 via cmd, use cmd.exe /c test.exe prm1 prm2. Though I don't really understand what this has to do with the crashes. Sounds like your problem is with test.exe - find out what's causing it to crash, and that will help you fix your C# code so that you don't need the cmd.

One of the places I would examine is the working directory. When you set it to "dump", are you sure the current directory is what you expect? Try using a full path first. It's possible that test.exe happens to be in the system path so it gets executed, but its working directory is not what it expects, and this causes it to crash.

try this:

ProcessStartInfo processToRunInfo = new ProcessStartInfo();    
processToRunInfo.Arguments = "Arguments");
processToRunInfo.CreateNoWindow = true;
processToRunInfo.WorkingDirectory = "C:\\yourDir\\";
processToRunInfo.FileName = "test.exe";
//processToRunInfo.CreateNoWindow = true;
//processToRunInfo.WindowStyle = ProcessWindowStyle.Hidden;
Process process = new Process();
process.StartInfo = processToRunInfo;
process.Start();

Process p = new Process();
p.StartInfo.WorkingDirectory = "/full/path/to/dump";
p.StartInfo.FileName = "/full/path/to/test.exe";
p.StartInfo.Arguments = s; // will call 'text.exe s'
p.Start();

Take a look at MSDN.

You need to Create an instance of the StartInfo class and user Start() such as

ProcessStartInfo startInfo = new ProcessStartInfo("IExplore.exe");
startInfo.WindowStyle = ProcessWindowStyle.Minimized;
Process.Start(startInfo);
startInfo.Arguments = "www.example.com";
Process.Start(startInfo);

Try it!

Rewriting your code would look something like this:

ProcessStartInfo startInfo = new ProcessStartInfo("test.exe");
startInfo.WindowStyle = ProcessWindowStyle.Minimized;
startInfo.WorkingDirectory = "dump";
startInfo.Arguments = "s";
Process.Start(startInfo);
