在Visual Studio中以特定行号打开文件 [英] Open a file in Visual Studio at a specific line number

问题描述

我有一个实用程序（grep），它给我一个文件名和行号的列表。在我确定devenv是打开文件的正确程序后，我想确保它在指定的行号打开。在emac中，这将是：

  emacs +140 filename.c 
  pre> 
 
 
我没有找到这样的Visual Studio（devenv）。我找到的最近的是：
  devenv /命令Edit.Goto 140filename.c 
  
但是，这会为每个这样的文件创建一个单独的devenv实例。 
 
 
 
这些变体重复使用现有的devenv，但不要去指定的行：
  devenv / CommandEdit.Goto 140/编辑filename.c 
 devenv /命令/编辑filename.cEdit.Goto 140 
  
我以为使用多个/ Command参数可能会做到，有正确的一个，因为我得到错误或根本没有响应（除了打开一个空的devenv）。
 
 
 
我可以为devenv写一个特殊的宏，但我会像这个实用程序被没有那个宏的其他人使用。 
 
 
 
有没有想法？
 
 
 
 
 
 
好吧，似乎没有办法这样做，因为我想要的。由于它看起来像我需要有专门的代码启动Visual Studio，我决定使用EnvDTE如下所示。希望这将有助于别人。

解决方案
一种使用直接命令行选项执行此操作的方法。看起来你必须为它写一个宏。 
  devenv / commandMacros.MyMacros.Module1.OpenFavoriteFiles
  
所以，你可以创建一个宏，它接受文件名和行号，然后打开文件并跳转到正确的地点。但是，我不知道你可以指定一个相同的实例标志某处，或不。
 
I have a utility (grep) that gives me a list of filenames and a line numbers. After I have determined that devenv is the correct program to open a file, I would like to ensure that it is opened at the indicated line number. In emacs, this would be:
emacs +140 filename.c
I have found nothing like this for Visual Studio (devenv). The closest I have found is:
devenv /Command "Edit.Goto 140" filename.c
However, this makes a separate instance of devenv for each such file. I would rather have something that uses an existing instance.

These variations re-use an existing devenv, but don't go to the indicated line:
devenv /Command "Edit.Goto 140" /Edit filename.c
devenv /Command  /Edit filename.c "Edit.Goto 140"
I thought that using multiple "/Command" arguments might do it, but I probably don't have the right one because I either get errors or no response at all (other than opening an empty devenv).

I could write a special macro for devenv, but I would like this utility to be used by others that don't have that macro. And I'm not clear on how to invoke that macro with the "/Command" option.

Any ideas?



Well, it doesn't appear that there is a way to do this as I wanted. Since it looks like I'll need to have dedicated code to start up Visual Studio, I've decided to use EnvDTE as shown below. Hopefully this will help somebody else.

解决方案
I can't figure out a way to do this with straight command-line options. It looks like you will have to write a macro for it. Supposedly, you can invoke them like so.
devenv /command "Macros.MyMacros.Module1.OpenFavoriteFiles"
So, you can probably create a macro that takes a filename and a line number, then opens the file and jumps to the proper place. But, I don't know that you can specify a same-instance flag somewhere, or not.
