Methods

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

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.
