Need help urgent with error!!
I got this code (a snippet):
Code:
class PrintMenu
{
public int Hoofdmenu()
{
try{
Console.Clear();
int Keuze = 0;
Console.WriteLine("**** Welkom bij het DBA project van Vandersteegen Jan ****");
Console.WriteLine("----------------------------------------------------------\n\n");
Console.WriteLine("Kies wat u wilt doen: \n");
Console.WriteLine(" |***********************************************************************|");
Console.WriteLine(" | 1: Inlezen van CSV bestand met nieuwe gebruikers om aan te maken. |");
Console.WriteLine(" | 2: Exporteren van bestaande gebruikers naar een CSV bestand |");
Console.WriteLine(" | 3: Verwijderen van bestaande gebruikers op basis van een CSV bestand |");
Console.WriteLine(" | 4: Afsluiten van het programma |");
Console.WriteLine(" |***********************************************************************| \n\n");
Console.Write("U keuze: ");
Keuze = int.Parse(Console.ReadLine());
return Keuze;
}
catch (Exception ex)
{
......
at the part where it says: Keuze = int.Parse(Console.ReadLine());
I get an error. It looks like it keeps skipping the readline part and just tries to convert nothing to a integer.
I tried making a seperate string variable for my input and then converting it to an int but that just gives me the same error... just like its skipping the readline like I said, and doesn't wait for my input :s
Any help would be very appreciated.
to be exact it's this error:
Quote:
System.ArgumentNullException: Argument cannot be null.

this all works in windows visual studio but not in monodeveloper 2.2 on linux
