如何以静态方法访问实例成员

Question

我有一个名为ApiHandler的类，它是一个泛型。现在，我在该类中声明了两个实例变量，并希望通过静态方法对其进行访问。 到目前为止，这就是我尝试过的方式

    public class ApiHandler<T> where T : class
    {
        private readonly IConfiguration _configuration;
        private readonly IHttpContextAccessor _contextAccessor;

        public ApiHandler(IConfiguration configuration, IHttpContextAccessor contextAccessor)
        {
            _configuration = configuration;
            _contextAccessor = contextAccessor;
        }

        #region Normal
        public static async Task<T> GetAsync(string url)
        {
            using (var client = new HttpClient())
            {
                // can't access this `_configuration` here
                string baseUrl = _configuration.GetSection("BaseUrl").Value;

                client.BaseAddress = new Uri("https://localhost:44345/api/");

                // Get token from cookies here

                var responseTask = await client.GetAsync(url);

                if (responseTask.IsSuccessStatusCode)
                {
                    return await responseTask.Content.ReadAsAsync<T>();
                }
                else
                {
                    throw new Exception("Server error. Please contact administrator.");
                }
            }
        }
}

在这里，我想访问_configuration方法内部的GetAsync变量，该方法是静态方法。 我怎样才能做到这一点 请帮帮我！！！
