How to make my function more generic ??

How to make my function more generic ??

• R_Vogel

  its all good Thanks!
  
  I didnt put <T> near the function name

  I believe this falls under the category of polymorphism.
  
  I haven't worked much with polymorphism in C#, but I believe the principles should be the same as other languages.
  
  If you derive a class from another type, you can use that more generic (or abstract) type to reference that object. Lets say we have an abstract class Shape, you could inherit the characteristics of that abstract class into your classes.
  
  class Oval : Shape {...};
  class Rectangle : Shape {...};
  class Square : Rectangle {...};
  class Circle : Oval {...};
  
  etc...
  
  and now you can have one generic function which will act on a Shape object:
  
  Circle c;
  Square sq;
  Shape s = c;
  Shape s2 = sq;
  
  GenericFoo(s);
  GenericFoo(s2);
  
  void GenericFoo(Shape s)
  {
  Shape shapeArray[] = GetArray();
  for(int n=0;n<shapeArray.Lenght;n++)
  {
  console.WriteLine(shapeArray);
  }
  }
  
  I can't test this right now but I hope this gets the idea across.

  If you want to use generics, the following code will take an array of most any type and print out the class name:

      void UseArray<T>(T[] classArray)
      {
        foreach (T classInstance in classArray)
        {
          Console.WriteLine(classInstance.GetType().Name);
        }
      }
  

  Here is a complete example:

  namespace ConsoleApplication3
  {
    // Declare two classes
    class Class1 { } 
    class Class2 { }
  
    class Program
    {
      // Initialize and return the classes in an array
      public Object[] GetArray(int option)
      {
        Object[] myArray;
        if (option == 1) return new Class1[2] { new Class1(), new Class1() };
        else return new Class2[2] { new Class2(), new Class2() };      
      }
  
      // One function to use both types of arrays
      void UseArray<T>(T[] classArray)
      {
        foreach (T classInstance in classArray)
        {
          Console.WriteLine(classInstance.GetType().Name);
        }
      }
  
      // Code to call UseArray
      static void Main(string[] args)
      {
        Program program = new Program();
        Object[] classArray;
        classArray = program.GetArray(1);
        program.UseArray((Class1[])classArray);
        classArray = program.GetArray(2);
        program.UseArray((Class2[])classArray);
        Console.ReadLine();
      }
    }
  }
