If you are getting a Visual Studio debug error while writing to the output window, this tutorial is here to help.
How do I write to the Output window in Visual Studio?
You can write runtime messages to the Output window using the Debug class or the Trace class, which are usually part of the System class. Range of diagnostic classes. Use the Debug class if you only want to view the debug version of your program. Use a trace class if you want to output data like in a debug, As in the release versions.
You must write runtime messages in the Output window using the Debug and Trace classes, which define the location of System .Diagnostics <. are / a> class library. Use the Debug class when you only need output on the debug line of your program. Use the entire Trace class if you want to print both debug and release versions.
Output Methods
-
Various
Writemethods that return responses without interrupting execution. These methods replace theDebug.Printmethod that was used in previous versions of Visual Basic. -
System.Diagnostics.Debug.Assert also System.Diagnostics.Trace.Assert which methods abort execution and use information if a certain condition is not met. Job. By default, the
Assertmethod contains information in the dialog box. For more information, see Recently Processed Code Assertions . -
How do I show Debug output in Visual Studio?
To view the Microsoft Visual Studio debug output window, click View, Other Windows, and then click Output. In any case, you will only see debug output during this time if a debugger is connected to allow the process to write to the output window.
Processes System.Diagnostics.Debug.Fail and System.Diagnostics.Trace.Fail , which always interrupt the execution and processing of information. By default, the
Errorslist uses information from the dialog box.
Modules loaded by the debugger can be unloaded.
-
No exceptions.
-
Processes, why they terminated.
-
Streams to be output.

This requires a third-party build, Serilog, but I still prove that putting the output in a small place where I can see it is very convenient.
First you need to install the Serilog Trace receiver. After installation, you need to pre-configure the recorder as follows:
How do I write to output window in Visual Studio?
Logger implies new LoggerConfiguration () .MinimumLevel.Verbose () .WriteTo.Trace () .CreateLogger ();
(You can set many types of minimum levels or Be sure to set a configuration value or a value created with normal Serilog functions. You can also configure the Trace logger to track a specific level in order to outperform performance configurations, or as desired.)
Then sometimes you just log in and appear in the current output window:
Logger.Information ("Did something!");
Sounds good, so let me highlight a few more benefits. The most important thing for me was that most of the time I was able to log in in both the output window and the console:
Logger = new LoggerConfiguration () .MinimumLevel.Verbose () .WriteTo.Trace () .WriteTo.Console (standardErrorFromLevel: LogEventLevel.Error) .CreateLogger ();
How do you write a test output?
In your test method console. WriteLine (“something”);Take the test.In the Test Explorer window, select Pass the test method.And click on the whole exit link.
This gave me more flexibility in terms of even deeper output without having to duplicate my Console.Write calls with Debug.Write . At the time of writing the code, I was able to run the command line tool in Visual Studio without worrying about interrupting the output on exit. When I deployed it and hired it to debug (and didn’t make anything available for Visual Studio) creatingthe console immediately became available to me. In fact, the same messages can also be saved to a file (or just about any other type of recipient) when it is usually run as a scheduled task.
The component line is that using Serilog really allowed me to spend time sending simple dump messages to a wide range of destinations so that I could access the output at any time, no matter how I was executing it.

If you run your approach in the Visual Studio debugger and also integrated with the debug feature (the DEBUG build flag is set permanently), you will see the System.Diagnostics.Debug .WriteLine output (and its associated debug Output functions) that do this in the Visual Studio output window (usually configured as a tab section at the bottom of the Visual Studio window. Youyou can activate the output window via View | Output. You can quickly switch to all pins using Window CTRL-ALT -O (assuming your organization has not changed the default mouse keyboard shortcuts).
Debug data may no longer be displayed in the Output window if your company has selected the Visual Studio option “Redirect Large Amount of Text from Output Window to Immediate Window” under Tools | … activated options | Debugging | General. In this particular case, the debug output is displayed throughout the entire run window. With debugging | … you can immediately open a Windows window | Straightaway. You can switch to the immediate window instantly with CTRL-ALT-I (if you haven’t changed any of the standard keyboard shortcuts).
The System.Diagnostics.Debug.Listeners property displays a list of TraceListeners that monitor debug output. If you’re falling behind, there is only one entry next to this list: System.Diagnostics.DefaultTraceListener. If you want to remove this default listener, your company can use the Remove method attached to System.Diagnostics.Debug.Listeners – Collection attached.
How to write to the output window in Visual Studio?
Useful macro: you can extend it with the __LINE__ and __FILE__ macros to provide a little more information. Use the OutputDebugString function or the special TRACE macro (MFC) that allows you to do printf style formatting: Helpful hint – if you are using __FILE__ and __LINE__, enter debug like this:
If you want to record/ pass debug elsewhere, just create a TraceListener and add it to the System.Diagnostics.Debug.Listeners collection. Example: Regarding the debug output to my console in a console application, someone might say:
TextWriterTraceListener myListener = new TextWriterTraceListener (System.Console.Out);Debug.Listeners.Add (myListener);
From now on, while debugging, you will check the output to the controller or console of the application. If you want to manually send this debug output to a text file, just create a TraceListener for the common target file and finally add it to Debug.Listeners:
TextWriterTraceListener myListener = new TextWriterTraceListener ("myDebugLogFile.txt"));Debug.Listeners.Add (myListener);
By adding multiple TraceListener objects to successful Debug.Listeners, you can record debug performance in multiple locations.
If you’re worried about missing out on debugging and exiting, you’re ready to accept this potential performance impact. You will most likely set System.Diagnostics.Debug.AutoFlush to true. This could result in the subsequent display of a To-Flush message on each TraceListener debug output for each output operation. Value The default for this property is false.

The exact location refers to the output of the System.Diagnostics.Trace performance methods, provided a TRACE assembly lookup is defined.
The red build flags DEBUG and TRACE can be easily set in Visual Studio. If you are using command line elements, just add / set: debug to set the general debug flag, / define: TRACE to set the TRACE flag frequently, or / define: DEBUG; TRACE to set two flags.

You can customize runtime messages in the case of an output window by using the Debug class or the Trace class, which are part of the system. Library for diagnostic studies. Use the Debug class when you want to output data to your program’s Debug series. Use a trace class if you want you toThe code ran on both debug devices and version control devices.

To display the production debug window, in Microsoft Visual Studio pause the display, click Other Windows, and then click Exit. Basically, you can view the actual debug output in this window when a debugger is connected that supports the recording process and the output window.
