Passing Multiple Commadline Args. to Console app from Windows app.

Yatish Bhavsar

Hello Friends,

I have a Windows application which calls a Console application and passes 5 command line arguments to that. I'm facing some problem to it.
the console app throughing an exception "Insput string was not in correct format".

Following is code:

string cmdexePath = @"D:\SortProgram\SortProgram\Executable\TS_PD.exe";
            //notice the quotes around the below string...
            string myApplication = cmdexePath + " " + "D:\\SortedFile.txt D:\\FixFormat.txt "+ " " + GlobalClass.Global.DetPath + " " + MergeFields +" 10000";
            //the /K keeps the CMD window open - even if your windows app closes
           // string cmdArguments = String.Format("/K {0}", myApplication);
            string cmdArguments = myApplication;
            System.Diagnostics.ProcessStartInfo psi = new System.Diagnostics.ProcessStartInfo(cmdexePath,cmdArguments);
            System.Diagnostics.Process p = new System.Diagnostics.Process();
            p.StartInfo = psi;
            p.Start();

please reply it's urgent,
thanks.

Where is that error message coming from? It is probably coming from the console program therefore you need to look at the program's documentation or the program's source code.

Note that you are passing cmdexePath twice; once in myApplication and again in the ProcessStartInfo. My guess is that you don't need to pass cmdexePath in myApplication. One more thing; you might need to have double quotes around the filenames in the parametrs that the console program "sees".
