我们可以在代码库的根目录创建一个名为 “.gitignore” 的文件，并在其中配置哪些文件或文件夹可以在提交的时候被忽略。以 .NET 项目为例，我们需要忽略与 VS 或 调试编译有关的 bin\obj\packages.vs 等文件或文件夹，则只需要：
# Emacs backup files *~ appsettings.local.json local.settings.json *.pfx # The below are a selected subset from # https://github.com/github/gitignore/blob/master/VisualStudio.gitignore # Visual Studio user-specific files *.suo *.user *.userosscache *.sln.docstates # Build results *.dll *.dll.config *.exe *.exe.config [Dd]ebug/ [Dd]ebugPublic/ [Rr]elease/ [Rr]eleases/ x64/ x86/ bld/ [Bb]in/ [Oo]bj/ [Ll]og/ # Visual Studio 2015/2017 cache/options directory .vs/ # Visual Studio 2017 auto generated files Generated\ Files/ # MSTest test Results [Tt]est[Rr]esult*/ [Bb]uild[Ll]og.* # .NET Core project.lock.json project.fragment.lock.json artifacts/ **/Properties/launchSettings.json # Files built by Visual Studio *_i.c *_p.c *_i.h *.ilk *.meta *.obj *.pch *.pdb *.pgc *.pgd *.rsp *.sbr *.tlb *.tli *.tlh *.tmp *.tmp_proj *.log *.vspscc *.vssscc .builds *.pidb *.svclog *.scc # Visual Studio profiler *.psess *.vsp *.vspx *.sap # Visual Studio Trace Files *.e2e # Visual Studio code coverage results *.coverage *.coveragexml # Click-Once directory publish/ # Publish Web Output *.[Pp]ublish.xml *.azurePubxml # Note: Comment the next line if you want to checkin your web deploy settings, # but database connection strings (with potential passwords) will be unencrypted *.pubxml *.publishproj # Microsoft Azure Web App publish settings.

注意，按行配置约束，一行一个。
