通过遵循给定提交的父链接来列出可到达的提交（例如`git rev-list`）

Question

Is there a way to list all commits that are reachable from HEAD using libgit2sharp library like git rev-list HEAD do?

There is a function ReferenceCollectionException.ReachableFrom , but it returns the list of refs pointed at particular commit:

let repo = new Repository("C:\path\to\repo")
let c = repo.Lookup<Commit>("HEAD")
let commits = repo.Refs.ReachableFrom([c])

And commits contains only 4 elements:

[ refs/heads/vNext => "63f8d6d90f06f4578604b57502f2c6b8aabf4479"
, refs/remotes/origin/HEAD => refs/remotes/origin/vNext => "63f8d6d90f06f4578604b57502f2c6b8aabf4479"
, refs/remotes/origin/ntk/issue_953 => "d5ced8c64e5ea9f6ba2135a72d59da2208215c6c"
, refs/remotes/origin/vNext => "63f8d6d90f06f4578604b57502f2c6b8aabf4479"
]

But there are much more nested parents commits of HEAD :

>> git rev-list HEAD | wc -l
1730

The following piece of code should help you accomplish what you're after

var filter = new CommitFilter { Since = repo.Head };

foreach (var commit in repo.Commits.QueryBy(filter))
{
    Console.WriteLine(commit.Sha);
}
