Methods

	Name	Description
	Close	Closes the Writer so that it no longer receives tracing or debugging output. (Inherited from TextWriterTraceListener.)
	CreateObjRef	Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
	Dispose	Releases all resources used by the TraceListener. (Inherited from TraceListener.)
	Dispose(Boolean)	Infrastructure. Disposes this TextWriterTraceListener object. (Inherited from TextWriterTraceListener.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Fail(String)	Emits an error message to the listener you create when you implement the TraceListener class. (Inherited from TraceListener.)
	Fail(String, String)	Emits an error message and a detailed error message to the listener you create when you implement the TraceListener class. (Inherited from TraceListener.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	Flush	Flushes the output buffer for the Writer. (Inherited from TextWriterTraceListener.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetLifetimeService	Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	GetSupportedAttributes	Gets the custom attributes supported by the trace listener. (Inherited from TraceListener.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	InitializeLifetimeService	Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	MemberwiseClone(Boolean)	Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	TraceData(TraceEventCache, String, TraceEventType, Int32, Object)	Writes trace information, a data object and event information to the listener specific output. (Inherited from TraceListener.)
	TraceData(TraceEventCache, String, TraceEventType, Int32, Object)	Writes trace information, an array of data objects and event information to the listener specific output. (Inherited from TraceListener.)
	TraceEvent(TraceEventCache, String, TraceEventType, Int32)	Writes trace and event information to the listener specific output. (Inherited from TraceListener.)
	TraceEvent(TraceEventCache, String, TraceEventType, Int32, String)	Writes trace information, a message, and event information to the listener specific output. (Inherited from TraceListener.)
	TraceEvent(TraceEventCache, String, TraceEventType, Int32, String, Object)	Writes trace information, a formatted array of objects and event information to the listener specific output. (Inherited from TraceListener.)
	TraceTransfer	Writes trace information, a message, a related activity identity and event information to the listener specific output. (Inherited from TraceListener.)
	Write(String)	Writes a message to this instance's Writer. (Inherited from TextWriterTraceListener.)
	Write(Object)	Writes the value of the object's ToString method to the listener you create when you implement the TraceListener class. (Inherited from TraceListener.)
	Write(String, String)	Writes a category name and a message to the listener you create when you implement the TraceListener class. (Inherited from TraceListener.)
	Write(Object, String)	Writes a category name and the value of the object's ToString method to the listener you create when you implement the TraceListener class. (Inherited from TraceListener.)
	WriteIndent	Writes the indent to the listener you create when you implement this class, and resets the NeedIndent property to false. (Inherited from TraceListener.)
	WriteLine(String)	Writes a message to this instance's Writer followed by a line terminator. The default line terminator is a carriage return followed by a line feed (\r\n). (Inherited from TextWriterTraceListener.)
	WriteLine(Object)	Writes the value of the object's ToString method to the listener you create when you implement the TraceListener class, followed by a line terminator. (Inherited from TraceListener.)
	WriteLine(String, String)	Writes a category name and a message to the listener you create when you implement the TraceListener class, followed by a line terminator. (Inherited from TraceListener.)
	WriteLine(Object, String)	Writes a category name and the value of the object's ToString method to the listener you create when you implement the TraceListener class, followed by a line terminator. (Inherited from TraceListener.)

Remarks

Unlike the TextWriterTraceListener, the EqtTextWriterTraceListener can be used in multiple instances across application domains and test adapters to append trace information to the same file. However, this method is not thread safe.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
