如何使用c#中的Octokit.Net Git Data API在主GitHub中检索和更新大于1MB的文件

using Octokit;

var github = new GitHubClient(new ProductHeaderValue("YourAppName"));
// 或者使用Personal Access Token进行身份验证
var github = new GitHubClient(new ProductHeaderValue("YourAppName"))
{
    Credentials = new Credentials("YourPersonalAccessToken")
};

var references = await github.Git.Reference.GetAll(owner, repo);
var masterReference = references.SingleOrDefault(r => r.Ref == "refs/heads/master");

var masterTree = await github.Git.Tree.Get(owner, repo, masterReference.Object.Sha);
var files = masterTree.Tree.Where(t => t.Size > 1024 * 1024 && t.Type == TreeType.Blob);

var newBlob = new NewBlob
{
    Content = "New file content",
    Encoding = EncodingType.Utf8
};
var blob = await github.Git.Blob.Create(owner, repo, newBlob);

var newTree = new NewTree();
newTree.Tree.Add(new NewTreeItem
{
    Path = "path/to/file",
    Mode = "100644",
    Type = TreeType.Blob,
    Sha = blob.Sha
});

var tree = await github.Git.Tree.Create(owner, repo, newTree);
var newCommit = new NewCommit("Commit message", tree.Sha, masterReference.Object.Sha);
var commit = await github.Git.Commit.Create(owner, repo, newCommit);
await github.Git.Reference.Update(owner, repo, masterReference.Ref, new ReferenceUpdate(commit.Sha));
