Exception:System.IndexOutOfRangeException (Urgent)
-
hi friends can anyone plz guide me on the exception
An unhandled exception of type 'System.IndexOutOfRangeException' occurred in system.windows.forms.dll Additional information: Index was outside the bounds of the array.heres the code that gives me the exceptionint count=4; int[] indice = new int[count]; MessageBox.Show(count.ToString()); for(int i=0;i<--Exception return indice;plz reply quicklyint count=4; int[] indice = new int[count]; MessageBox.Show(count.ToString()); for(int i=0;i indice[i] = TableListBox.CheckedIndices[i];<--Exception return indice;this is not C# coding -
can you tell me what is this? for(int i=0;i indice[i] = TableListBox.CheckedIndices[i];<--Exception
sorry about that i copied the incorrect code. the for loop looks like this
int count=4; int[] indice = new int[count]; for(int i=0;i<count;i++) { indice[i] = TableListBox.CheckedIndices[i]; } return indice;TableList Box is a CheckedListBox. what this loop does is takes the item on the selected index of the list box and stores it in another array. -

check the size of TableListBox.it should not be greater than count
the size property of the listbox just gives its width and height. what has that got to do with the exception??

i am not talking about the physical size. i am talking about the count. check during run time.just place a brek point in the for loop and see whether TableList[i] is not greater than TableList[count]. right??

int count = TableListBox.CheckedIndices.Count;and continue the rest of your code -

int count=TableListBox.CheckedIndices.Count;approach. but still it doesn't work. Any other suggestions??? -

Why do you say that. (NB. the forum cut off everything after "for(int i=0;i" the line should have read "for(int i=0;i<count;i++)")
It is a good notice from you X| But i didn't know that the forum cut that out. Why don't u try to help that poor guy instead of loosing your time on unrelavent comments

can this be due to the .Net Platform being corrupt? i'm really confused:confused::~

Is it the first time you develop on this Platform?

The odds of that are close to zero.

Well, it's a really simple one. You need to step through the code and see what's happening, if you need to do that, to be convinced that hard coding the number 4 when the list could have less items is a bad idea. You'll see that it blows up because there are not four items checked. Nothing else makes sense.
