将监视的Visual Studio变量输出到文件 [英] Output a watched Visual Studio variable to a file

问题描述

在Visual Studio(如果需要的话，2008年)中是否有一种方法可以在调试/中断模式下将变量的内容写入文本/XML文件?

Is there a way in Visual Studio (2008 if it matters) that I can, in debug/break mode, write the contents of a variable to a text/XML file?

这种情况是，我在调试中运行的过程很长，而我意识到为时已晚，因为我没有记录有关该进程正在监视的事件的足够详细信息，但是幸运的是，在代码.

The scenario is that I have a long process running in debug and I have realised too late that I haven't logged enough detail about the events that the process has been monitoring, but fortunately a history is still available within a variable in the code.

我可以在此列表中浏览成千上万的项目，但是一旦我在应用程序上按一下stop，它就不会持续下去……没有明显的上下文选项，但是有什么办法，那就更好了比手动方式?还是没有希望，我只需要按一下停止按钮，重新设置日志记录功能，然后再次运行它就可以了?

I could trawl through the tens of thousands of items in this list, but it's not going to persist once I hit stop on the application ... there is no obvious context option for this, but is there any way, a better way than manual? Or is there no hope and I just need to hit stop, re-tool the logging function and run the thing again?

除了尝试达到断点，修改代码并重新编写以使记录器更好之外，还有没有一种方法可以不丢失内存中的数据?

Aside from trying to hit a breakpoint, modify the code and re-write to make a better logger, is there a way of not losing that in-memory data?

推荐答案

一种方法是使用即时窗口(菜单 Debug -> Windows - > 立即).在出现的窗口中，您可以使用?"查询变量的值.

One way to do it would be to use the immediate window (menu Debug -> Windows -> Immediate). In the window that appears you can use the "?" to query the value of a variable.

假设您的历史记录变量是一个字符串，则可以通过在立即窗口中键入以下内容来查看其内容:

Assuming your history variable is a string you view its contents by typing the following in the immediate window:

?history

您可以将输出复制并粘贴到文本文件中，或者要求Visual Studio记录所有命令窗口的输出.为此，请执行以下操作:

You could copy and paste the output from there into a text file or alternatively ask Visual Studio to log all command window output. To do this type:

>log "c:\test.log"
?history
>log off

Log是Tools.LogCommandWindowOutput的别名，并接受以下参数:

Log is an alias for Tools.LogCommandWindowOutput and accepts the following parameters:

Tools.LogCommandWindowOutput [filename] [/on|/off] [/overwrite]
