Object parameters sorted in Ascending Order

Question

Dear all,

I have public class with its parameters like 

public class Student

{

   public int No{get; Set;}

   public string Name{get; set;}

   public date DOJ{get; set;}

   public string Address{get; set;}

}

Now, In my code behind window i created object for Student class and i assigned values, which i got from my front end like

Student objStudent=new Student();

objStudent.No=txtNo.text;

objStudent.Name=txtName.text;

objStudent.DOJ=txtDOJ.text;

objStudent.Address=txtAddress.text;

While passing this student object to my InsertDetails method its going as sorted way based on its parameters like

Address

DOJ

Name

No

In my code I am passing student object as a parameter to my Stored Procedure. So I am getting error that parameter mismatch.

Here I am not getting the reason that why the parametes get sorted while passing.

It should be in proper way that how i defined like No, Name, DOJ, Address

Can Somebody let me know what will be the issue?
