Попытка Отпусти размер массива 1227136 и получить ошибку 413(413) Request Entity Too Large в WCF
Это, как я отправляю данные из wreb APPLICATION-
protected void Page_Load(object sender, EventArgs e)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost:59624/RestServiceImpl.svc/PostFileRest");//Path for local
request.Timeout = Timeout.Infinite;
request.KeepAlive = true;
request.ContentType = "application/vnd.ms-excel";
/*---------------------------------------------------------------------------*/
string excelTojson = excelToJson();
byte[] fileData = Encoding.ASCII.GetBytes(excelTojson);
/*---------------------------------------------------------------------------*/
request.ContentLength = fileData.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(fileData, 0, fileData.Length);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
System.Diagnostics.Debug.Assert(response.StatusCode == HttpStatusCode.OK);
string responseMessage = string.Empty;
using (System.IO.StreamReader sr = new System.IO.StreamReader(response.GetResponseStream()))
{
responseMessage = sr.ReadToEnd();
}
Response.Write(responseMessage);
}
#region excelToJson
public string excelToJson()
{
var pathToExcel = @"E:\My_Work\MVC\Test1.xlsx";
OleDbConnection MyConnection;
DataTable dt;
OleDbDataAdapter MyCommand;
MyConnection = new OleDbConnection("provider=Microsoft.ACE.OLEDB.12.0;Data Source='" + pathToExcel + "';Extended Properties='Excel 12.0 Xml;HDR=YES'");
MyCommand = new System.Data.OleDb.OleDbDataAdapter("select * from [Sheet1$]", MyConnection);
MyCommand.TableMappings.Add("Table", "TestTable");
dt = new DataTable();
MyCommand.Fill(dt);
MyConnection.Close();
string jsonString = string.Empty;
return jsonString = JsonConvert.SerializeObject(dt);
}

Мой WCF код где я получаю данные, когда отправляю небольшой объем данных, тогда он работает нормально. Но я хочу отправить большие данные.

Возможные дубликатом [IIS7 - (413) Request Entity Too Large | uploadReadAheadSize] (http://stackoverflow.com/questions/10122957/iis7-413-request-entity-too-large-uploadreadaheadsize) – Esko
@Esko Я назначил maxReceivedMessageSize и readerQuotas. Это можно проверить в конфиге. Я также использую messageEncoding = «Mtom». Но пока я не получу проблему. –
Установили ли вы эти настройки как на стороне клиента, так и на стороне обслуживания? – Esko
