How can calculate the mode using array. Im only a beginner in programming. its for our finals project

Question

I'm having trouble getting accurate results on my code to get the mode. it is based on the users input. can anyone help please? this is the code I'm working on for days

    string[] ArrModeInput = new string[20];
    //USER INPUT
    Console.WriteLine("Please Enter 20 Numbers ");
    //TO INPUT
    for (int stats = 0; stats < ArrModeInput.Length; stats++)
    {
        ArrModeInput[stats] = Console.ReadLine();
    }

    //CONDITION 
    for (int stats = 0; stats < ArrModeInput.Length; stats++)
    {
        //ArrModeInput[stats] = Console.ReadLine();
        int Count = 0;
        for (int m = 0; m < ArrModeInput.Length; m++)
            if (ArrModeInput[stats] == ArrModeInput[m])
                Count = Count + 1;
        Console.WriteLine("\t\n Mode is " + ArrModeInput[stats] + ". It ocuurs " + Count + " times");
    }
