The results are not in the Output window but in the Test Results Detail (TestResult Pane at the bottom, right click on on Test Results and go to TestResultDetails).

This works with Debug.WriteLine and Console.WriteLine.

The Trace messages can occur in the output window as well, even if you're not in debug mode.
You just have to make sure the the TRACE compiler constant is defined.

blocks|key|2059138|text|Trace.WriteLine方法是一个有条件编译的方法。这意味着只有在编译代码时定义了跟踪常量时，才会执行跟踪常量。默认情况下，在Visual+Studio中，跟踪仅在调试模式下定义。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2059139|右键单击项目并选择属性。转到编译选项卡。选择Release模式并向已定义的预处理器常量添加跟踪。这应该会为你解决这个问题。|2059140|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

The Trace.WriteLine method is a conditionally compiled method. That means that it will only be executed if the TRACE constant is defined when the code is compiled. By default in Visual Studio, TRACE is only defined in DEBUG mode. 

Right Click on the Project and Select Properties. Go to the Compile tab. Select Release mode and add TRACE to the defined preprocessor constants. That should fix the issue for you.

blocks|key|2059185|text|对我来说，这是因为debug.writeline显示在即时窗口中，而不是输出中。默认情况下，我安装的VS2013甚至没有显示打开即时窗口的选项，因此您必须执行以下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2059186|Select+Tools+->+Customize+

For me this was the fact that debug.writeline shows in the Immediate window, not the Output. My installation of VS2013 by default doesn't even show an option to open the Immediate window, so you have to do the following:

<pre><code>Select Tools -&gt; Customize 
Commands Tab
View | Other Windows menu bar dropdown
Add Command...
The Immediate option is in the Debug section.
</code></pre>

Once you have Ok'd that, you can go to View -> Other Windows and select the Immediate Window and hey presto all of the debug output can be seen.

Unfortunately for me it also showed about 50 errors that I wasn't aware of in my project... maybe I'll just turn it off again :-)

To write in the Visual Studio output window I used <code>IVsOutputWindow</code> and <code>IVsOutputWindowPane</code>. I included as members in my <code>OutputWindow</code> class which look like this : 

<pre><code>public class OutputWindow : TextWriter
{
 #region Members

 private static readonly Guid mPaneGuid = new Guid("AB9F45E4-2001-4197-BAF5-4B165222AF29");
 private static IVsOutputWindow mOutputWindow = null;
 private static IVsOutputWindowPane mOutputPane = null;

 #endregion

 #region Constructor

 public OutputWindow(DTE2 aDte)
 {
 if( null == mOutputWindow )
 {
 IServiceProvider serviceProvider = 
 new ServiceProvider(aDte as Microsoft.VisualStudio.OLE.Interop.IServiceProvider);
 mOutputWindow = serviceProvider.GetService(typeof(SVsOutputWindow)) as IVsOutputWindow;
 }

 if (null == mOutputPane)
 {
 Guid generalPaneGuid = mPaneGuid;
 mOutputWindow.GetPane(ref generalPaneGuid, out IVsOutputWindowPane pane);

 if ( null == pane)
 {
 mOutputWindow.CreatePane(ref generalPaneGuid, "Your output window name", 0, 1);
 mOutputWindow.GetPane(ref generalPaneGuid, out pane);
 }
 mOutputPane = pane;
 }
 }

 {
 mOutputPane.Activate();
 aDte.ExecuteCommand("View.Output", string.Empty);

If you have a big text to write in output window you usually don't want to freeze the UI. In this purpose you can use a <code>Dispatcher</code>. To write something in output window using this implementation now you can simple do this:

<pre><code>Dispatcher mDispatcher = HwndSource.FromHwnd((IntPtr)mDte.MainWindow.HWnd).RootVisual.Dispatcher;

using (OutputWindow outputWindow = new OutputWindow(mDte))
{
 mDispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(() =&gt;
 {
 outputWindow.Write("Write what you want here");
 }));
}
</code></pre>

In Java, you can use <code>System.out.println(message)</code> to print a message to the output window.

What's the equivalent in Visual Studio ?

I know when I'm in debug mode I can use this to see the message in the output window:

<pre><code>Debug.WriteLine("Debug : User_Id = "+Session["User_Id"]);
System.Diagnostics.Trace.WriteLine("Debug : User_Id = "+Session["User_Id"]);
</code></pre>

How can this be done without debugging in Visual Studio?

Display a message in Visual Studio's output window when not debug mode?

Visual Studio

编译器

Windows

Java

在Java语言中，您可以使用System.out.println(message)将消息打印到输出窗口。Visual Studio中的等价物是什么？我知道当我处于调试模式时，我可以使用此命令查看输出窗口中的消息：Debug.WriteLine("Debug : User_Id = "+Session["User_Id"]);System.Diagnostics.Trace.WriteLine("D
