c# - System.IndexOutOfRangeException when trying to copy data from list to 2d array -


i getting exception:

system.indexoutofrangeexception: 'index outside bounds of array.'

on col ++ when in second loop. trying put vales list> excel columns , rows. please let me know doing wrong.

object[,] cellvaluestowrite = new string[excelrange.rows.count, excelrange.columns.count];                 foreach (list<string> errorrecord in section.errorrecords) {     int rows = 0;     int col = 0;     int length = errorrecord.count;     foreach (var elem in errorrecord)     {         if (col < length)         {             cellvaluestowrite[rows, col] = elem;             col++;         }     }     rows++; }

if create array excelrange.rows.count , excelrange.rows.count 5 cannot access cellvaluestowrite[5, col] because indexing starts @ 0 , try access 6-th element way.

why not using old loop (especially if need indexing):

for (int row = 0; row < cellvaluestowrite.getlength(0); row++) {     (int col = 0; col < cellvaluestowrite.getlength(1); col++)     {         cellvaluestowrite[row, col] = section.errorrecords[row][col];     }    }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
