git rm

The following examples assume you already have a repository in place to work with. If not, see git-init.

Remove from a Initialized Repository

This will stage the specified file for removal from the Repo:

Git

$ git rm <file>

LibGit2Sharp

using (var repo = new Repository("<repoPath>"))
{
    // Removes the file
    repo.Index.Remove("<file>");
}

Example Code:

using (var repo = new Repository("<repoPath>"))
{
    // Create the committer's signature and commit
    Signature author = new Signature("Author", "@Author", DateTime.Now);
    Signature committer = author;

    // Remove the file
    repo.Index.Remove("<file>");

    // Commit to the repository
    Commit commit = repo.Commit(message, author, committer);
}
