EventLogEntryCollection.CopyTo Method

Copies the elements of the EventLogEntryCollection to an array of EventLogEntry instances, starting at a particular array index.

Namespace:  System.Diagnostics
Assembly:  System (in System.dll)

public void CopyTo(
	EventLogEntry[] entries,
	int index


Type: System.Diagnostics.EventLogEntry[]

The one-dimensional array of EventLogEntry instances that is the destination of the elements copied from the collection. The array must have zero-based indexing.

Type: System.Int32

The zero-based index in the array at which copying begins.

Because new entries are appended to the existing list, stepping through the collection enables you to access the entries that were created after you originally created the EventLogEntryCollection. An array of EventLogEntry instances is fixed at the time it is instantiated. Therefore, you cannot read new entries by using the array that is returned by the CopyTo method.

The following example creates an EventLogEntry array and uses the CopyTo method to copy the contents of an EventLogEntryCollection into it.

// Copy the EventLog entries to Array of type EventLogEntry.
EventLogEntry[] myEventLogEntryArray =
   new EventLogEntry[myEventLogEntryCollection.Count];
myEventLogEntryCollection.CopyTo(myEventLogEntryArray, 0);
IEnumerator myEnumerator = myEventLogEntryArray.GetEnumerator();
while (myEnumerator.MoveNext())
    EventLogEntry myEventLogEntry = (EventLogEntry)myEnumerator.Current;
    Console.WriteLine("The LocalTime the Event is generated is "
       + myEventLogEntry.TimeGenerated);
