ASP.NET Core 2中的HttpResponseBase.BufferOutput属性等效于什么?

public class ContentStreamingResult : ActionResult {

    private Action<Stream> _onExecuteAction;

    public ContentStreamingResult(Action<Stream> onExecuteAction) {
        _onExecuteAction = onExecuteAction;
    }

    public override void ExecuteResult(ControllerContext context) {
        var httpContext = context.HttpContext;
        httpContext.Response.BufferOutput = false;
        _onExecuteAction(httpContext.Response.OutputStream);
    }
}

根本没有 BufferOutput HttpResponse .NET核心中的类。

什么是等效的 HttpResponseBase.BufferOutput ASP.NET Core 2中的属性?
