Assembly:

Package:

Source:

Source:
EventLogEntryCollection.cs

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

public:
 void CopyTo(cli::array <System::Diagnostics::EventLogEntry ^> ^ entries, int index);
public void CopyTo (System.Diagnostics.EventLogEntry[] entries, int index);
member this.CopyTo : System.Diagnostics.EventLogEntry[] * int -> unit
Public Sub CopyTo (entries As EventLogEntry(), index As Integer)

Parameters

entries
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.

index
Int32

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

Examples

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);
}

' Copy the EventLog entries to Array of type EventLogEntry.
Dim myEventLogEntryArray(myEventLogEntryCollection.Count-1) As EventLogEntry
myEventLogEntryCollection.CopyTo(myEventLogEntryArray, 0)
Dim myEnumerator As IEnumerator = myEventLogEntryArray.GetEnumerator()
While myEnumerator.MoveNext()
   Dim myEventLogEntry As EventLogEntry = CType(myEnumerator.Current, EventLogEntry)
   Console.WriteLine("The LocalTime the Event is generated is " + _
                        myEventLogEntry.TimeGenerated)
End While

Remarks

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.
