How to pass object to angularjs controller using MVC controller Action

Your question is a bit vague , you need to be more specific on what exactly you are trying to do.

Generally , this his how you would get data in Angular from the MVC application.

In Case of MVC/WebAPI , you should use actions to return JSON result back to the angular service which can then be processed by angular. Example below :

  app.factory('myService', function($http) {
  var myService = {
    GetData: function() {
      // $http returns a promise, which has a then function, which also returns a promise
      var promise = $http.get('<ActionURL>').then(function (response) {
        // The then function here is an opportunity to modify the response
        console.log(response);
        // The return value gets picked up by the then in the controller.
        return response.data;
      });
      // Return the promise to the controller
      return promise;
    }
  };
  return myService;
});

app.controller('MainCtrl', function( myService,$scope) {
  // Call the async method and then do stuff with what is returned inside our own then function
  myService.GetData().then(function(d) {
    $scope.data = d;
  });
});

After this services is called from the MainCtrl , angular will have the data from the MVC action available in its $scope.data variable.
