Hello guys,
I write a code in console Application for search from the stack. I made the user defined data type of Person in user defined data type there are attributes of Person are name,age,address.
Now i want to search the data by using name and search it from the stack.

What I have tried:

public bool search_Person(Stack<Person>mystack,string name)
       {
           foreach(Person pr in mystack)
           {
               if (mystack==pr.name)
               {
                   return true;
               }
           }
           return false;
       }
   }
