c# - Deserialize a dynamic property in an ASP.net web-api -

i have element class contains anoptions property, option class can in turn change properties example have these 2

element1 = {     "id": "1",     "options": {         "printable": "true",         "stackoverflow": "great"     } }  element2 = {     "id": "2",     "options": {         "question": "awsome",         "propertydiferent": "empty"     } } 

on web api have method this:

public object post ([frombody] element element) {     savetomongo (element); } 

the element class:

public class element {     public dynamic options {get; set; }     public string id {get; set; } } 

when pick element mongo have no problems. when send using post method of api web, not deserialize itself, in expando object since mongo. how similar behavior @ both ends?

edit: tried change options dynamic newtonsoft jobject, didn't work. options saved, generate father don't want.

"options" : {             "_t" : "newtonsoft.json.linq.jobject, newtonsoft.json, version=6.0.0.0, culture=neutral, publickeytoken=30ad4fe6b2a6aeed",              "_v" : {                 "padding" : {                     "_t" : "jarray",                      "_v" : [                         {                             "_t" : "jvalue",                              "_v" : [                              ]                         },                          {                             "_t" : "jvalue",                              "_v" : [                              ]                         },                          {                             "_t" : "jvalue",                              "_v" : [                              ]                         },                          {                             "_t" : "jvalue",                              "_v" : [                              ]                         }                     ]                 },                  "image" : {                     "_t" : "jvalue",                      "_v" : [                      ]                 },                  "alt" : {                     "_t" : "jvalue",                      "_v" : [                      ]                 },                  "url" : {                     "_t" : "jvalue",                      "_v" : [                      ]                 },                  "width" : {                     "_t" : "jvalue",                      "_v" : [                      ]                 },                  "backgroundcolor" : {                     "_t" : "jvalue",                      "_v" : [                      ]                 },                  "text" : {                     "_t" : "jvalue",                      "_v" : [                      ]                 }             }         },  

there more properties because extracted example directly mongo.

first step, make ajax call javascript pass json string, otherwise dynamic property options not populated.

element.options = element.options.tostring (); 

so have json string although stored in mongo can recover without being modified. able return in api have deserialize before deserialization done controller itself.

element.options = jobject.parse (element.options); 

it uncool system, few disadvantages, not allow treatment of options in mongo. has been way in have managed passage mongo did not modify object.
