从远程删除分支

Question

This is regarding API of libgit2sharp Remote Fixture.

I know how to Delete a branch from Remote using Push RefSpec. However, I wanna know how to do it using the API. I tried following example,

Repo.Network.Push(Repo.Network.Remotes["origin"], objectish: null, destinationSpec: branchName);

I provided correct branchName (checked remote). However, I get,

Unhandled exception: System.ArgumentNullException: Value cannot be null. (Parameter 'objectish')
   at LibGit2Sharp.Core.Ensure.ArgumentNotNull(Object argumentValue, String argumentName) in D:\git_ws\libgit2sharp\LibGit2Sharp\Core\Ensure.cs:line 24
   at LibGit2Sharp.Network.Push(Remote remote, String objectish, String destinationSpec) in D:\git_ws\libgit2sharp\LibGit2Sharp\Network.cs:line 273

How to properly call Repo.Network.Push to delete a branch from remote.

Out of curiosity I also tried the example from RemoteFixture.cs like this,

var remoteBranchName = "origin/" + branchName;
Repo.Branches.Remove(remoteBranchName, true);

This doesn't throw any error. However, it does nothing. Branch still exists on remote.

Thank you. :)

Can you use the Push method that just takes push refspecs?

public virtual void Push(
            Remote remote,
            string pushRefSpec,
            PushOptions pushOptions)

The push refspec to delete references is described under the "Deleting references section here:

https://git-scm.com/book/en/v2/Git-Internals-The-Refspec

and would be similar to:
