Are you asking how to accept input into your WinForms app via the command line?

If so:

public static void Main(string[] args)
{
foreach (string arg in args)
System.Windows.Forms.MessageBox.Show(arg);
}

Executing an application with the above code as the Main entry point and the following command line will produce two message boxes,
each with one of the arguments specified:

MyApp.exe "c:\Path\File Name.txt" -Switch1

Hi Dave:
there is the thing:
i have a executable command for exampl is :abc
you can type abc in commandline then it will return a string.

then i want to use winform to do this, so write a C# code doing same
function as type abc in commandline window and return a string.
finally show this string in textfields.

the whole process won't pop up commandline window at all.

Thanks

You must change the Project output to "Console Application".

I think that Console.* uses an existing Console window, or creates one if it doesn't already exist for the current process. Your
output will go to a new console window in the context of a "Windows Application" Project, however, it will not remain open for user
input.

If you look real hard you may see the window pop-up for a second, display your string, and then close.

I'm not aware of any means for preventing a Console window from closing unless it is running in a "Console Application" Project.

Anyway, it's probably not a good design to have a Windows app displaying a Console window to display status, etc.

Use a StatusBar control, MessageBox.Show or EntryLog, etc..

Drop a button and a textbox onto a form. Create a batch file
(C:\test.bat) with something that will generate output (I used "ping
127.0.0.1"). Add this code to the button click event.


ProcessStartInfo ps = new ProcessStartInfo(@"C:\test.bat");
ps.RedirectStandardOutput = true;
ps.UseShellExecute = false;
Process p = Process.Start(ps);
this.textBox1.Text = p.StandardOutput.ReadToEnd();

Is that what you were after?
