How to get the current/active branch with LibGit2S

问题:

So using LibGit2Sharp https://github.com/libgit2/libgit2sharp you can walk through the branches like this

using (var repo = new Repository(@"path to .git"))
{
    foreach (var branch in repo.Branches)
    {
        Debug.WriteLine(branch.Name);   
    }
}

But how do I get the current/active branch?

回答1:

Branch.IsCurrentRepositoryHead should do the trick.

I think Repository.Head will also do the same thing if you don't want to iterate through the branches...

回答2:

I think that, instead of going through the branches and checking whether each branch is the current head, the simplest approach is to directly get the branch name from the repository Head:

using (var repo = new Repository(@"path to .git"))
{
    var currentBranchName = repo.Head.FriendlyName;
}

You can then obtain the branch itself via

repo.Branches[currentBranchName]
