Conditional to check if array is equal to a particular value-CodePudding

I am expecting this code to write "no hobbies" to the console. However, nothing is output. Why is this?

string[] hobbies = new string[0];
if (hobbies == new string[0])
  {
    Console.WriteLine("no hobbies");
  }

CodePudding user response：

You're comparing arrays, == in this case compares references and not values. If you want to compare the arrays' content, you could use SequenceEqual:

hobbies.SequenceEqual(new string[0])

CodePudding user response：

Array content can be compared using array.Equal(another_array) or array.SequenceEqual(another_array) . try this:

static void Main(string[] args)
    {
        string[] hobbies = new string [0];
        if(hobbies.SequenceEqual(new string[0]))
        {
            Console.WriteLine("no hobbies");
        }

        Console.ReadKey();
    }
