Can't get this to compile

Override the Scan method to return true if any value in the array is a repeat of the value immediately preceding it.

I just can't get this to compile!

SequenceDetector.cs 
namespace Treehouse.CodeChallenges
{
    class SequenceDetector
    {
        public virtual bool Scan(int[] sequence)
        {
            return true;
        }
    }
}
RepeatDetector.cs 
namespace Treehouse.CodeChallenges
{
    class RepeatDetector : SequenceDetector
    {
         public Overrride bool Scan(int[] sequence)
        {
           if (int i = 0; i <= sequence.Length; i++)
           {
               if (sequence[i].value == sequence[i-1].value)

           }
             return true;
        }
    }
}

You have some spelling errors. Change 'Overrride' to override and the first 'if' to 'for' where you have if (I =0....)

Actually, you have many mistakes. I suggest you watch the videos again!

I had problem with the logic, however I found some code that work and combined it here

namespace Treehouse.CodeChallenges { class RepeatDetector : SequenceDetector { public override bool Scan(int[] sequence) {

        for (int i = 1; i < sequence.Length; i++) 
           { 
                if (sequence[i - 1] == sequence[i])
                return true; 
           }

                return false;
    }
}

}
