Example

[Visual Basic, C#, C++] Note   This example shows how to use one of the overloaded versions of Exists. For other examples that might be available, see the individual overload topics.

[Visual Basic] 
Dim myLog As String = "myNewLog"
If EventLog.Exists(myLog) Then
   Console.WriteLine("Log '" + myLog + "' exists.")
Else
   Console.WriteLine("Log '" + myLog + "' does not exist.")
End If

[C#] 
string myLog = "myNewLog";
if (EventLog.Exists(myLog))
{
   Console.WriteLine("Log '"+myLog+"' exists.");
}
else
{
   Console.WriteLine("Log '"+myLog+"' does not exist.");
}

[C++] 
String* myLog = S"myNewLog";
if (EventLog::Exists(myLog)) {
    Console::WriteLine(S"Log '{0}' exists.", myLog);
} else {
    Console::WriteLine(S"Log '{0}' does not exist.", myLog);
