protected internal abstract Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken);

Task<HttpResponseMessage> task = _handler.SendAsync(request, cancellationToken);

如何调用受保护的方法？

Answer 1

不是protected。这是protected internal。这意味着“protected 或 internal”。该方法可以被同一程序集中的任何代码调用。

What is the difference between 'protected' and 'protected internal'?
