c# - Unable to get data from a particular WCF Service Operation which is sending files in response -


i have wcf service many methods, 2 of transferring files. 1 working correct, sends 3 files byte array in single row. other 1 sending list of database rows, each row has 1 docx file in it. when wcf client invokes operation, runs on server side , rows fetched database, after sends response, client receives following exception:

an error occurred while receiving http response http://localhost/service/service.svc. due service endpoint binding not using http protocol. due http request context being aborted server (possibly due service shutting down). see server l ogs more details. underlying connection closed: unexpected error occurred on receive.

the minimal code listed below:

[datacontract] public class document {     [datamember]     public int id { get; set; }      [datamember]     public string name { get; set; }      [datamember]     public byte[] file { get; set; }      [datamember]     public int schemaid { get; set; }      [foreignkey("schemaid")]     public virtual schema schema { get; set; } }  [servicecontract] public interface iservice {     [operationcontract]     list<document> getdocuments(int schemaid); }  public class service : iservice, idisposable {     dbcontext db = new dbcontext();     public list<document> getdocuments(int schemaid)     {         list<document> docs = db.documents.where(d => d.schemaid == schemaid).tolist();         return docs;     } }  public partial class serviceclient : system.servicemodel.clientbase<iservice>, iservice {     public document[] getdocuments(int schemaid)     {         return base.channel.getdocuments(schemaid);     } }  try {     serviceclient client = new serviceclient("basichttpbinding_iservice");     client.open();     list<document> docs = client.getdocuments(9).tolist();     client.close(); } catch{}

in wcf client config file, using default values of basichttpbinding. after received exception, tried increasing maxreceivedmessagesize on binding in client side, still receiving same exception.

please suggest, how can resolve this?

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
