如何在libgit2sharp中创建孤立分支？

我能找到的只是创建指向提交的分支的方法我正在寻找类似命令的效果：

git checkout --orphan BRANCH_NAME

git checkout --orphan BRANCH_NAME实际上将HEAD移动到未出生的分支BRANCH_NAME，而不改变工作目录和索引。

您可以使用HEAD方法更新repo.Refs.UpdateTarget()引用的目标，从而对LibGit2Sharp执行类似的操作。

以下测试演示了这个

[Fact]
public void CanCreateAnUnbornBranch()
{
    string path = CloneStandardTestRepo();
    using (var repo = new Repository(path))
    {
        // No branch named orphan
        Assert.Null(repo.Branches["orphan"]);

        // HEAD doesn't point to an unborn branch
        Assert.False(repo.Info.IsHeadUnborn);

        // Let's move the HEAD to this branch to be created
        repo.Refs.UpdateTarget("HEAD", "refs/heads/orphan");
        Assert.True(repo.Info.IsHeadUnborn);

        // The branch still doesn't exist
        Assert.Null(repo.Branches["orphan"]);

        // Create a commit against HEAD
        var signature = new Signature("Me", "me@there.com", DateTimeOffset.Now);
        Commit c = repo.Commit("New initial root commit", signature, signature);

        // Ensure this commit has no parent
        Assert.Equal(0, c.Parents.Count());

        // The branch now exists...
        Branch orphan = repo.Branches["orphan"];
        Assert.NotNull(orphan);

        // ...and points to that newly created commit
        Assert.Equal(c, orphan.Tip);
    }
}
