c# - Passing Object vs String as Method Paramter -

with following code, understand getstringagain(classone.str1) better getastring(classone) because want pass in necessary because of data hiding/encapsulation etc.

however, there memory benefits? classone object larger string, since in both methods, passing in reference object, , therefore reference copied stack, both efficient in terms of memory?

class classone() {     public string str1 = "string1";     public string str2 = "string2"; }  class classtwo() {     public classtwo()     {         classone classone = new classone();         string = getastring(classone);         string b = getstringagain(classone.str1)     }      private string getastring(classone classone)     {         return classone.str1;     }      private string getstringagain(string str)     {         return str;     } } 

string , class reference types

it means 2 functions take reference managed heap actual data held

nothing copied.

if know pointers basicly same passing pointer.
