Estoy tratando de publicar un Json en nuestro servicio web. Mi problema es que cuando request.ContentLength supera 7kb. Obtendré una excepción web 500 a pedido. GetResponse(). Pero si mi request.ContentLength es inferior a 7kb, mi publicación se envía correctamente.No se pudo publicar en WebRequest si la longitud del contenido> 7kb con C#
mensaje de error: Código de
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";

byte[] byteData = UTF8Encoding.UTF8.GetBytes(postData);
request.ContentLength = byteData.Length;
using (Stream postStream = request.GetRequestStream())

string JsonResponse = reader.ReadToEnd();

suena como el problema está probablemente en el servicio web ... –
Hola Jon, hmm el servicio web se configuró para permite 2147483647 petición longitud máxima. También tratamos de poner un punto de corte, pero el servicio web no recibió ninguna publicación. si la longitud del contenido es> 7kb –
Bueno, obtendrás un 500, lo que sugiere un error interno * en algún lugar *. Sugiero que eche un vistazo de cerca a todos los registros disponibles. –
