我不认为这是“按设计”，它只是“开箱即用”不可用。
我同意，使用行终止符而不是新行将多行调用添加到监视窗口会更好：
研究
我发现这个类似的问题有几个“解决方法”可供选择：
Multi-Line Watch Window in Visual Studio 2010?
我也在MSDN Forums by a MSFT Engineer找到了这条评论：
恐怕不支持，我们经常一一编辑。也许你可以提交这个功能请求：http://visualstudio.uservoice.com/forums/121579-visual-studio
推出您自己的 Visual Studio 插件
所以我自己尝试了一下，这绝不是生产代码，但它向您展示了如何做到这一点：
（点击图片放大）
namespace AddinMultiLineWatch
{
public class Connect : IDTExtensibility2, IDTCommandTarget
{
//ADD THESE MEMBER VARIABLES
//private DebuggerEvents _debuggerEvents = null;
//private _dispDebuggerEvents_OnEnterBreakModeEventHandler DebuggerEvents_OnEnterBreakMode;
private Window _watchWindow = null;
private CommandEvents _objCommandEvents;
private bool _isRecursive = false;
public Connect()
{
}
public void OnConnection(object application, ext_ConnectMode connectMode, object addInInst, ref Array custom)
{
_applicationObject = (DTE2)application;
_addInInstance = (AddIn)addInInst;
//SET THE MEMBER VARIABLES
//_debuggerEvents = _applicationObject.Events.DebuggerEvents;
//_debuggerEvents.OnEnterBreakMode += new _dispDebuggerEvents_OnEnterBreakModeEventHandler(BreakHandler);
//var watchWindow = _applicationObject.Windows.Item(EnvDTE.Constants.vsWindowKindWatch);
_objCommandEvents = _applicationObject.Events.CommandEvents;
_objCommandEvents.BeforeExecute += new _dispCommandEvents_BeforeExecuteEventHandler(BeforeExecute);
if(connectMode == ext_ConnectMode.ext_cm_UISetup)
{
object []contextGUIDS = new object[] { };
Commands2 commands = (Commands2)_applicationObject.Commands;
string toolsMenuName = "Tools";
Microsoft.VisualStudio.CommandBars.CommandBar menuBarCommandBar = ((Microsoft.VisualStudio.CommandBars.CommandBars)_applicationObject.CommandBars)["MenuBar"];
ar:
CommandBarControl toolsControl = menuBarCommandBar.Controls[toolsMenuName];
CommandBarPopup toolsPopup = (CommandBarPopup)toolsControl;
try
{
Command command = commands.AddNamedCommand2(_addInInstance, "AddinMultiLineWatch", "AddinMultiLineWatch", "Executes the command for AddinMultiLineWatch", true, 59, ref contextGUIDS, (int)vsCommandStatus.vsCommandStatusSupported+(int)vsCommandStatus.vsCommandStatusEnabled, (int)vsCommandStyle.vsCommandStylePictAndText, vsCommandControlType.vsCommandControlTypeButton);
if((command != null) && (toolsPopup != null))
{
command.AddControl(toolsPopup.CommandBar, 1);
}
}
catch(System.ArgumentException)
{
}
}
}
//ADD THIS METHOD TO INTERCEPT THE DEBUG.ADDWATCH COMMAND
public void BeforeExecute(string Guid, int ID, object CustomIn, object CustomOut, ref bool CancelDefault)
{
EnvDTE.Command objCommand = default(EnvDTE.Command);
try
{
objCommand = _applicationObject.Commands.Item(Guid, ID);
}
catch (Exception ex)
{
}
if ((objCommand != null))
{
if (objCommand.Name == "Debug.AddWatch")
{
//if (_isRecursive) return;
//_isRecursive = true;
TextSelection selection = (TextSelection)_applicationObject.ActiveDocument.Selection;
//TODO make selection goto next semi-colon/Line Terminator...
var selText = selection.Text;
if (string.IsNullOrEmpty(selText)) return;
//Only intercept multi-line Add Watch commands
if (selText.Contains(Environment.NewLine))
{
//THE BLACK MAGIC: make it fit in one line! lol
selText = selText.Replace(Environment.NewLine, string.Empty);
//THIS CALL IS RECURSIVE, I'LL LEAVE IT TO THE READER AS AN EXERCISE TO SOLVE..
_applicationObject.ExecuteCommand("Debug.AddWatch", selText);
}
}
}
}

完成向导
将上面的代码添加到 Connect.cs 类 - 请参阅我的 //UPPERCASE cmets 以及要添加的内容。
在TextSelection selection = (TextSelection)_applicationObject.ActiveDocument.Selection;这一行打断点
按 F5，将启动一个新的 VS 实例 > 选择 New Project > Console App > 将其命名为 TestMultilineAddWatch
-
在Console App的program.cs中，指定2行以上的代码调用，并在其上打断点，如截图所示，eg：
Add(1, //Breakpoint here and select both lines
2);
}
static int Add(int i, int j)
{
return i + j;
}
TestMultilineAddWatch 解决方案中的 F5 以及当代码控制在断点处停止时 > 选择/突出显示这两行 Add(1, \r\n 2) > 右键单击 > Add Watch
在 VS IDE 调试上下文菜单中单击 Add Watch 会导致 VS AddinMultiLineWatch 解决方案拦截调用并激活，并在断点处暂停......您将在此处看到 将多行代码替换为一行发送到监视窗口的黑魔法。
调用自身的 Visual Studio EXEC 命令使此方法递归，如果您对其进行调试，手动退出递归，您将看到按照我的屏幕截图的结果。
调试愉快！
