Solution 1

Why not use the args parameter of your Main method? That is exactly what it is there for...

"able to show me some example, becourse i am not good in console app and batch file also"

Batch file:

myAppName ParameterText MoreParameters

Your app:

C#

static void Main(string[] args)
   {
   foreach (string arg in args)
      {
      Console.WriteLine(arg);
      }
   }

Output:

ParameterText
MoreParameters

hi, thanks for the fast respone..
i try to write something like below at my batch file
START "C:\myFiles\FileControl\FileControl\bin\Debug\FileControl" "C:\\A" "C:\\AA"
pause
but it seem can't perform the function..
is my batch file write something wrong?

Don't use the START command: http://www.robvanderwoude.com/start.php
You don't need it unless you are trying to start the app in a different session - with the pause there, you definitely don't need that.
And you can probably dump the double quotes round the parameters, and the spare '\' characters as well: check with Console.WriteLine

Just get rid of the START - will probably cure it.

hi i changed the coding to
"C:\myFiles\FileControl\FileControl\bin\Debug\FileControl.exe" "%C:\\A" "%C:\\AA"
But i get the result for
Console.WriteLine(args[0].toString()); return: \\A
Console.WriteLine(args[1].toString()); return: \\AA
how to make it return "C:\\A" or "C:\\AA" ? the "C:" are missing... :S

OriginalGriff 23-Aug-11 5:33am

This may be a stupid question, but here we go...
Why have you inserted a '%' character in front of the "C:" part of your parameters?
You do realize that '%' is a special character in batch files which indicates a parameter to the batch file itself? So the "%C:" part will be removed?

Member 2321293 23-Aug-11 5:36am

Yap.. did a stupid thing just now.. haha i should take it off and also the "," it should not at there also..
my problem solve.. thanks
if should be like:
"C:\myFiles\FileControl\FileControl\bin\Debug\FileControl.exe" "C:\\A" "C:\\AA" 5 ".txt"

Solution 2

Use a Process object.
How to launch Windows applications (Notepad) / Call Batch files from a C#/.NET console application.[^] is a good article that should help you out.
