c# - Create instance of an unknown type and work with it -

-

I have a controller in MVC that checks the role of authenticated user. The basis of its role on the role of making an example of a class For example, if the role is "student", then I have to make an example of a student class. I am trying to do something like that but it does not work: 

  Private user current user; Switch (roll) {case "student": current user = context.students. FirstOther Default (STD = & gt; STD.USIRID == WebSure.ContentUserIDID); break; . . . }

But I can not define student properties, for example, when I want to get CurrentUser.firstname, no such property is available! How can I retrieve the current user?

You defined CurrentUser as the object type. This will not have the properties of student , unless you insert it. 

  Private User Current User;

You can use an interface or common base class, e.g. 

  public class person {public string first name {get; Set; }} Public class students: Add special properties for persons {// students} Professors of the public: person {// Add special properties for the professors}

then 

 Use  Private person current user; All properties available for   
  person  will be available at  CurrentUser . If you need access to such property which is only on  student , then you can cast such a way: 
 
  (Student current user). Some decent theme

In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
