| ImmediateFlush | Gets or set whether the appender will flush at the end of each append operation.
| Layout | Gets or sets the ILayout for this appender. (Inherited from AppenderSkeleton.)
| Name | Gets or sets the name of this appender. (Inherited from AppenderSkeleton.)
| QuietWriter | Gets or sets the QuietTextWriter where logging events will be written to.
| RequiresLayout | This appender requires a log4net.Layout to be set. (Overrides AppenderSkeleton RequiresLayout.)

Methods

| Name | Description
--- | --- | ---
| ActivateOptions | Initialize the appender based on the options set (Inherited from AppenderSkeleton.)
| AddFilter | Adds a filter to the end of the filter chain. (Inherited from AppenderSkeleton.)
| Append(LoggingEvent) | This method is called by the DoAppend(LoggingEvent) method. (Overrides AppenderSkeleton Append(LoggingEvent).)
| Append( LoggingEvent ) | This method is called by the DoAppend( LoggingEvent ) method. (Overrides AppenderSkeleton Append( LoggingEvent ).)
| ClearFilters | Clears the filter list for this appender. (Inherited from AppenderSkeleton.)
| Close | Closes the appender and release resources. (Inherited from AppenderSkeleton.)
| CloseWriter | Closes the underlying TextWriter.
| DoAppend(LoggingEvent) | Performs threshold checks and invokes filters before delegating actual logging to the subclasses specific [M:Append(LoggingEvent)] method. (Inherited from AppenderSkeleton.)
| DoAppend( LoggingEvent ) | Performs threshold checks and invokes filters before delegating actual logging to the subclasses specific [M:Append(LoggingEvent[])] method. (Inherited from AppenderSkeleton.)
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
| FilterEvent | Test if the logging event should we output by this appender (Inherited from AppenderSkeleton.)
| Finalize | Finalizes this appender by calling the implementation's Close method. (Inherited from AppenderSkeleton.)
| Flush | Flushes any buffered log data. (Overrides AppenderSkeleton Flush(Int32).)
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.)
| GetType | Gets the Type of the current instance. (Inherited from Object.)
| IsAsSevereAsThreshold | Checks if the message level is below this appender's threshold. (Inherited from AppenderSkeleton.)
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.)
| OnClose | Close this appender instance. The underlying stream or writer is also closed. (Overrides AppenderSkeleton OnClose .)
| PreAppendCheck | This method determines if there is a sense in attempting to append. (Overrides AppenderSkeleton PreAppendCheck .)
| PrepareWriter | Called to allow a subclass to lazily initialize the writer
| RenderLoggingEvent(LoggingEvent) | Renders the LoggingEvent to a string. (Inherited from AppenderSkeleton.)
| RenderLoggingEvent(TextWriter, LoggingEvent) | Renders the LoggingEvent to a string. (Inherited from AppenderSkeleton.)
| Reset | Clears internal references to the underlying TextWriter and other variables.
| ToString | Returns a String that represents the current Object. (Inherited from Object.)
| WriteFooter | Writes a footer as produced by the embedded layout's Footer property.
| WriteFooterAndCloseWriter | Writes the footer and closes the underlying TextWriter.
| WriteHeader | Writes a header produced by the embedded layout's Header property.

Remarks

An Appender that writes to a TextWriter.

This appender may be used stand alone if initialized with an appropriate writer, however it is typically used as a base class for an appender that can open a TextWriter to write to.
