![]() | EntryWrittenEventArgs() | Initializes a new instance of the EntryWrittenEventArgs class. |
![]() | EntryWrittenEventArgs(EventLogEntry) | Initializes a new instance of the EntryWrittenEventArgs class with the specified event log entry. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
The following example demonstrates the EntryWrittenEventArgs constructor. It creates a custom EventLog object and writes an entry into it. Then it creates an EntryWrittenEventArgs object using the first entry in the custom EventLog. This object is used to notify a message.
using System; using System.Diagnostics; class MySample { public static void Main() { try { EventLog myNewLog = new EventLog(); myNewLog.Log = "MyNewLog"; myNewLog.Source = "MySource"; // Create the source if it does not exist already. if (!EventLog.SourceExists("MySource")) { // An event log source should not be created and immediately used. // There is a latency time to enable the source, it should be created // prior to executing the application that uses the source. // Execute this sample a second time to use the new source. EventLog.CreateEventSource("MySource", "MyNewLog"); Console.WriteLine("CreatingEventSource"); Console.WriteLine("Exiting, execute the application a second time to use the source."); // The source is created. Exit the application to allow it to be registered. return; } // Write an entry to the EventLog. myNewLog.WriteEntry("The Latest entry in the Event Log"); int myEntries = myNewLog.Entries.Count; EventLogEntry entry = myNewLog.Entries[myEntries - 1]; EntryWrittenEventArgs myEntryEventArgs = new EntryWrittenEventArgs(); MyOnEntry(myNewLog, myEntryEventArgs); } catch (Exception e) { Console.WriteLine("Exception Raised" + e.Message); } } protected static void MyOnEntry(Object source, EntryWrittenEventArgs e) { if (e.Entry == null) Console.WriteLine("A new entry is written in MyNewLog."); } }
