Sto tentando di inviare un Json al nostro servizio web. Il mio problema è che quando la mia richiesta.ContentLength supera 7kb. Riceverò un'eccezione web 500 su richiesta. GetResponse(). Ma se la mia richiesta.ContentLength è inferiore a 7kb, il mio post è stato inviato con successo.Impossibile pubblicare su WebRequest se Lunghezza contenuto> 7kb utilizzando C#
messaggio di errore: Codice di
The remote server returned an error: (500) Internal Server Error.

public static string JsonPost(string url, string method, string postData)
{
Uri address = new Uri(url + method);
HttpWebRequest request = WebRequest.Create(address) as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/json";
byte[] byteData = UTF8Encoding.UTF8.GetBytes(postData);
request.ContentLength = byteData.Length;
using (Stream postStream = request.GetRequestStream())
{
postStream.Write(byteData, 0, byteData.Length);
}
try

using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)

StreamReader reader = new StreamReader(response.GetResponseStream());
string JsonResponse = reader.ReadToEnd();
return JsonResponse;

suona come il problema è probabilmente nel servizio Web ... –
Hi Jon, hmm il servizio web è stato configurato in modo da permette 2147483647 lunghezza massima richiesta. Abbiamo anche provato a inserire un punto di interruzione, ma il servizio web non ha ricevuto alcun post. se la lunghezza del contenuto> 7kb –
Bene, stai ricevendo un 500 - che suggerisce un errore interno * da qualche parte *. Ti suggerisco di dare un'occhiata da vicino a tutti i registri disponibili. –
