Overloading the + operator to add two arrays

Question

What\'s wrong with this C# code? I tried to overload the + operator to add two arrays, but got an error message as follows:

One of the parameters of a binary operato

Answer 1

Its states that one of the parameters to the operator needs to be of the same type as the operator function is a member of. So if the operator function is a member of MyClass on of the parameters needs to be of type MyClass.

class MyClass
{
 ...

public static int[] operator+(MyClass x, int[] y)
  // public static int[] Add(int[] x, int[] y)
  {
      int[] z = new int[x.Length];

      for (int i = 0; i < x.Length; i++)
      {
        z[i] = x[i] + y[i];
      }

      return (z);
  }
}
