HttpStatusCode是任何500类型

Question

我想知道是否有更简单的方法（更好的方法）来检查500状态代码？

我能想到的唯一方法就是：

var statusCodes = new List<HttpStatusCode>()
{
  HttpStatusCode.BadGateway,
  HttpStatusCode.GatewayTimeout,
  HttpStatusCode.HttpVersionNotSupported,
  HttpStatusCode.InternalServerError,
  HttpStatusCode.NotImplemented,
  HttpStatusCode.ServiceUnavailable
};
if (statusCodes.Contains(response.StatusCode))
{
  throw new HttpRequestException("Blah");
}

我注意到这些是500种类型：

• BadGateway
• GatewayTimeout
• HttpVersionNotSupported
• InternalServerError
• NotImplemented
• ServiceUnavailable

以5xx开头的状态代码是服务器错误，因此简单的方法是

if ((int)response.StatusCode>=500 && (int)response.StatusCode<600)
      throw new HttpRequestException("Server error");
