Prevent Visual Studio 2015 from removing line continuation characters (_) in VB.NET files
提问by Paolo Crociati
I'm opening some old VB.NET projects in Visual Studio 2015 and when I edit the code, VS changes the syntax:
我在 Visual Studio 2015 中打开了一些旧的 VB.NET 项目，当我编辑代码时，VS 更改了语法：
It removes "_" in concatenations:
它在串联中删除“_”：
'Before
myString = "ABC" & _
"DEF"
'After
myString = "ABC" &
"DEF"
or add a space before !:
或在 ! 之前添加一个空格：
'Before
myDatatable.Rows(0)!myColumn
'After
myDatatable.Rows(0) !myColumn
This syntax isn't compatible with Visual Studio 2010 or 2013.
此语法与 Visual Studio 2010 或 2013 不兼容。

I had the same problem, and I was able to fix it by disabling the "Pretty listing" option in the editor. You can find this option here:
我遇到了同样的问题，我可以通过禁用编辑器中的“漂亮列表”选项来修复它。您可以在此处找到此选项：
Tools > Options > Text Editor > Basic > Advanced > Editor Help > Pretty listing (reformatting) of code
I'm not sure what other auto-reformatting this option disables, but at least the editor stopped removing the line continuation characters in old code/projects.
我不确定其他自动重新格式化此选项会禁用什么，但至少编辑器停止删除旧代码/项目中的行继续符。
PS: While the Roslyn team says they fixed this (see links below), this bug is still present in the latest version of Visual Studio 2015.
PS：虽然 Roslyn 团队表示他们修复了这个问题（见下面的链接），但这个错误仍然存在于最新版本的 Visual Studio 2015 中。

The official way to address this is modifying the .vbproj file to include
解决此问题的官方方法是修改 .vbproj 文件以包含

Just CTRL-Z to undo the removal of the underscores right after Visual Studio (2015-19) "fixes" it for you. This leaves the "Pretty Listing" feature turned on but restores the missing underscores. Thanks David Carta for the answer left as a comment.
在 Visual Studio (2015-19) 为您“修复”后，只需按 CTRL-Z 即可撤消删除下划线的操作。这使得“漂亮列表”功能处于打开状态，但会恢复丢失的下划线。感谢 David Carta 作为评论留下的答案。
