这三个Visual Studio Solution Explorer图标之间有什么区别？

Question

I am seeing 3 different types of icons directly to the right of my .cs filenames in Visual Studio Community 2017 Version 15.8.1 I'm curious as to what they mean. I checked out: https://docs.microsoft.com/en-us/visualstudio/ide/class-view-and-object-browser-icons?view=vs-2017 but couldn't find these icons.

I'm thinking it might be from a plugin or something? not sure. There is no common thread linking them as far as GIT, compilation status or errors. I'm brand new to VS and C#, so these things bother me.

thanks!

Answer 1

This is all related to source control, in your case GIT

• The lock icon means the file is source controlled and not currently modified or has any pending changes. If you hover over in VS you will see the status as "Checked In".

• The plus icon means its a new file that has yet to be added to source control. If you hover over in VS you will see the status as "Pending Add".

• The red check icon means there is a pending change that is yet to be committed. If you hover over in VS you will see the status as "Pending Edit".

Answer 2

1. The lock means the file is unchanged from the version in source control.
2. The plus means it's a new file not yet tracked in source control.
3. The red tick means the file has been changed and not yet committed to source control.
