Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)

[HostProtectionAttribute(SecurityAction.LinkDemand, Synchronization = true)]
public sealed class IisTraceListener : TraceListener

The IisTraceListener type exposes the following members.

  NameDescription
Public methodIisTraceListenerInitializes a new instance of the IisTraceListener class.

  NameDescription
Public propertyAttributesGets the custom trace listener attributes defined in the application configuration file. (Inherited from TraceListener.)
Public propertyFilterGets and sets the trace filter for the trace listener. (Inherited from TraceListener.)
Public propertyIndentLevelGets or sets the indent level. (Inherited from TraceListener.)
Public propertyIndentSizeGets or sets the number of spaces in an indent. (Inherited from TraceListener.)
Public propertyIsThreadSafeGets a value indicating whether the trace listener is thread safe. (Inherited from TraceListener.)
Public propertyNameGets or sets a name for this TraceListener. (Inherited from TraceListener.)
Public propertyTraceOutputOptionsGets or sets the trace output options. (Inherited from TraceListener.)

  NameDescription
Public methodCloseWhen overridden in a derived class, closes the output stream so it no longer receives tracing or debugging output. (Inherited from TraceListener.)
Public methodCreateObjRefCreates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
Public methodDispose()Releases all resources used by the TraceListener. (Inherited from TraceListener.)
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodFail(String)Emits an error message to the listener you create when you implement the TraceListener class. (Inherited from TraceListener.)
Public methodFail(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.)
Public methodFlushWhen overridden in a derived class, flushes the output buffer. (Inherited from TraceListener.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetLifetimeServiceRetrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Protected methodGetSupportedAttributesGets the custom attributes supported by the trace listener. (Inherited from TraceListener.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodInitializeLifetimeServiceObtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodTraceData(TraceEventCache, String, TraceEventType, Int32, Object)Infrastructure. Writes trace information, a data object, and event information to the output of the IisTraceListener class. (Overrides TraceListener.TraceData(TraceEventCache, String, TraceEventType, Int32, Object).)
Public methodTraceData(TraceEventCache, String, TraceEventType, Int32, Object[])Infrastructure. Writes trace information, an array of data objects, and event information to the output of the IisTraceListener class. (Overrides TraceListener.TraceData(TraceEventCache, String, TraceEventType, Int32, Object[]).)
Public methodTraceEvent(TraceEventCache, String, TraceEventType, Int32)Writes trace and event information to the listener specific output. (Inherited from TraceListener.)
Public methodTraceEvent(TraceEventCache, String, TraceEventType, Int32, String)Infrastructure. Writes trace and event information to the output of the IisTraceListener class. (Overrides TraceListener.TraceEvent(TraceEventCache, String, TraceEventType, Int32, String).)
Public methodTraceEvent(TraceEventCache, String, TraceEventType, Int32, String, Object[])Infrastructure. Writes trace information, a formatted array of objects, and event information to the output of the IisTraceListener class. (Overrides TraceListener.TraceEvent(TraceEventCache, String, TraceEventType, Int32, String, Object[]).)
Public methodTraceTransferWrites trace information, a message, a related activity identity and event information to the listener specific output. (Inherited from TraceListener.)
Public methodWrite(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 methodWrite(String)Writes the specified message to the output of the IisTraceListener class. (Overrides TraceListener.Write(String).)
Public methodWrite(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.)
Public methodWrite(String, String)Writes the specified message and the specified category name to the output of the IisTraceListener class. (Overrides TraceListener.Write(String, String).)
Public methodWriteLine(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 methodWriteLine(String)Writes the specified message to the output of the IisTraceListener class. (Overrides TraceListener.WriteLine(String).)
Public methodWriteLine(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.)
Public methodWriteLine(String, String)Writes the specified message and category name to the output of the IisTraceListener class. (Overrides TraceListener.WriteLine(String, String).)

The IisTraceListener class connects the tracing mechanism of ASP.NET to IIS 7.0. This listener class enables developers who create ASP.NET applications and who implement the IHttpModule and IHttpHandler interfaces to raise page-level, module-level, or handler-level events to the IIS 7.0 infrastructure when tracing is enabled.

NoteNote

This listener class does not route IIS 7.0 events to ASP.NET classes. This includes the Page class and classes that implement the IHttpModule or IHttpHandler interface.

IisTraceListener is introduced in the .NET Framework 3.5. For more information, see .NET Framework Versions and Dependencies.

NoteNote

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: Synchronization. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

.NET Framework

Supported in: 4.5.2, 4.5.1, 4.5, 4, 3.5 SP1, 3.0 SP1, 2.0 SP1

Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)

The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.

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