All command line parameters are passed to your application through string[] args
parameter.
The code below shows an example:
using System.Linq;
namespace MyApp
{
class Program
{
static void Main(string[] args)
{
if (args.Contains("/REPORT1"))
{
/* Do something */
}
else if (args.Contains("/REPORT2"))
{
/* Do something */
}
}
}
}
Then, in command prompt just use:
C:\MyApp\MyApp.exe /REPORT1
