c# - Error: System.InvalidOperationException in ASP.NET WebAPI -

i'm trying enter data database , access_token on end of successful call.

when make call passing parameters:

everything goes fine, user gets registered , saved database, , access_token returns user:

but, when add signs +, = or \ in deviceid value exception , nothing saved in database:

this model definition call:

public class registration     {         public string username { get; set; }         public string password{ get; set; }         public string deviceid { get; set; }         public string devicename { get; set; }     } 

field deviceid gets saved database username, , it's definition nvarchar(1024)

is possible nvarchar doesn't allow characters not letters , numbers? did else had problem this?

edit: method problem is:

[route("registration/request")] public async task<httpresponsemessage> registrationrequest(registration model) {     try     {         matrixlogmanager.info("starting token creating.");          var request = httpcontext.current.request;         var tokenserviceurl = request.url.getleftpart(uripartial.authority) + request.applicationpath + "/token";          matrixlogmanager.info("checking if model valid.");         if (!modelstate.isvalid)         {             return request.createresponse(badrequest(modelstate));         }         using (matrixservicelayerlogin login = new matrixservicelayerlogin())         {             if (login.loginuser(model.username, model.password, true, true))             {                 var personid = login.getpersonid();                  matrixlogmanager.debug("user " + model.username + "successfully logged in on matrixsts.");                 try                 {                     using (var authrepo = new authrepository())                     {                         applicationuser appuser = new userfactory().createapplicationuser(model, personid);                         identityresult result = await authrepo.registeruser(appuser);                         emailservice.sendemail(appuser);                         ihttpactionresult errorresult = geterrorresult(result);                          if (errorresult != null)                         {                             return request.createresponse(errorresult);                         }                          using (var client = new httpclient())                         {                             var requestparams = new list<keyvaluepair<string, string>>                                                 {                                                     new keyvaluepair<string, string>("grant_type", "password"),                                                     new keyvaluepair<string, string>("username", appuser.username),                                                     new keyvaluepair<string, string>("password", "0000")                                                 };                              var requestparamsformurlencoded = new formurlencodedcontent(requestparams);                             var tokenserviceresponse = await client.postasync(tokenserviceurl, requestparamsformurlencoded);                             var responsestring = await tokenserviceresponse.content.readasstringasync();                             var responsecode = tokenserviceresponse.statuscode;                             var responsemsg = new httpresponsemessage(responsecode)                             {                                 content = new stringcontent(responsestring, encoding.utf8, "application/json")                             };                              responsemsg.headers.add("psk", appuser.psk);                             return responsemsg;                         }                     }                 }                 catch (exception ex)                 {                     matrixlogmanager.error("error: ", ex);                     throw ex;                 }             }             else             {                 return request.createerrorresponse(httpstatuscode.unauthorized, "invalid username or password.");             }         }     }     catch (exception ex)     {         matrixlogmanager.error(string.format("error while trying registring user: exception = {0} innerexception {1}", ex.message, ex.innerexception.message));         throw;     } } 

try-catch not catch exception, real exception happens here:

public async task<identityresult> registeruser(applicationuser usermodel) {     usermodel.twofactorenabled = true;     usermodel.psk = timesensitivepasscode.generatepresharedkey();      var result = await _usermanager.createasync(usermodel, "0000");      return result; } 

when line result returns client. i've gues saving in line before doesn't go well. set try-catch in part of code , post exception.

this happens when you're wrapping response twice.

consider method returns task<ihttpactionresult> instead of task<httpresponsemessage> , note how wrapping errorresult twice when calling:

return request.createresponse(errorresult); 

this leading believe errors in token service causing issue, when double-wrapping in fact :)

consider following:

[route("registration/request")] public async task<ihttpresult> registrationrequest(registration model) {     try     {         matrixlogmanager.info("starting token creating.");          var request = httpcontext.current.request;         var tokenserviceurl = request.url.getleftpart(uripartial.authority) + request.applicationpath + "/token";          matrixlogmanager.info("checking if model valid.");         if (!modelstate.isvalid)         {             return badrequest(modelstate);         }         using (matrixservicelayerlogin login = new matrixservicelayerlogin())         {             if (login.loginuser(model.username, model.password, true, true))             {                 var personid = login.getpersonid();                  matrixlogmanager.debug("user " + model.username + "successfully logged in on matrixsts.");                 try                 {                     using (var authrepo = new authrepository())                     {                         applicationuser appuser = new userfactory().createapplicationuser(model, personid);                         identityresult result = await authrepo.registeruser(appuser);                         emailservice.sendemail(appuser);                         ihttpactionresult errorresult = geterrorresult(result);                          if (errorresult != null)                         {                             // major change here                             return errorresult;                         }                          using (var client = new httpclient())                         {                             var requestparams = new list<keyvaluepair<string, string>>                                                 {                                                     new keyvaluepair<string, string>("grant_type", "password"),                                                     new keyvaluepair<string, string>("username", appuser.username),                                                     new keyvaluepair<string, string>("password", "0000")                                                 };                              var requestparamsformurlencoded = new formurlencodedcontent(requestparams);                             var tokenserviceresponse = await client.postasync(tokenserviceurl, requestparamsformurlencoded);                             var responsestring = await tokenserviceresponse.content.readasstringasync();                             var responsecode = tokenserviceresponse.statuscode;                             var responsemsg = new httpresponsemessage(responsecode)                             {                                 content = new stringcontent(responsestring, encoding.utf8, "application/json")                             };                              responsemsg.headers.add("psk", appuser.psk);                             return responsemsg;                         }                     }                 }                 catch (exception ex)                 {                     matrixlogmanager.error("error: ", ex);                     throw ex;                 }             }             else             {                 return request.createerrorresponse(httpstatuscode.unauthorized, "invalid username or password.");             }         }     }     catch (exception ex)     {         matrixlogmanager.error(string.format("error while trying registring user: exception = {0} innerexception {1}", ex.message, ex.innerexception.message));         throw;     } }
