如何在异常中读取CreateErrorResponse自定义消息

Question

I can't see CreateErrorResponse message in exception. I am passing message "Invalid Parameters" to ThrowResponseException method but i can't read it in exception.

e.Response.RequestMessage gives default detail message but i only need to read "Invalid Parameters".

try
{
  If (!ValidString)
  { ThrowResponseException(HttpStatusCode.BadRequest, "Invalid Parameters");}
}
catch (HttpResponseException e)
{
    msg = " Status Code: " + e.Response.StatusCode.ToString();
}

private void ThrowResponseException(HttpStatusCode statusCode, string message)
{
    var errorResponse = Request.CreateErrorResponse(statusCode,message);
    throw new HttpResponseException(errorResponse);
}

Answer 1

I found something similar where they wrap the message in a new exception and pass that exception into the create response. Then they can pull out the text of the error message. How can I retrieve the exception message from Request.CreateErrorResponse?

return Request.CreateResponse(statusCode, new Exception(message));
