Random movement of char in console c#

Question

I made a maze game in a console application and by using keys I can control character to leave the maze. Now I want to figure out how to automate that process So that my character can go by random directions and try to find the way out. Here is my class. The problem is in the randomMovement Method.

class Player: Maze
{
    public int x = 1;
    public int y = 1;


    public string playerName;

    public static void printMv() {
        while (true)
        {
            for (int i = 0; i < 15; i++)
            {


                Console.Clear();
                mazeDev();

                Console.Write("0");
                Thread.Sleep(1000);
            }
        }
    }


    public static void movementByUser()
    {

        int x = 1, y = 1;
        while (true)
        {

            Console.Clear();
            mazeDev();
            Console.CursorLeft = x;
            Console.CursorTop = y;
            Console.Write("0");


            ConsoleKeyInfo mv = Console.ReadKey();
            if (mv.Key == ConsoleKey.Escape) break;
            if (mv.Key == ConsoleKey.A && mazeBluePrint[y, x - 1] == 0) {
                x--;
            }
            if (mv.Key == ConsoleKey.D && mazeBluePrint[y, x + 1] == 0)
            {
                x++;
            }
            if (mv.Key == ConsoleKey.W && mazeBluePrint[y - 1, x] == 0)
            {
                y--;
            }
            if (mv.Key == ConsoleKey.S && mazeBluePrint[y + 1, x] == 0)
            {
                y++;
            }
        }
    }
    public static void randomMovement()
    {
        Random randMove = new Random();

        int x = 1;
        int y = 1;

        int irandom = randMove.Next(4);
        Console.CursorLeft = x;
        Console.CursorTop = y;

        if (irandom == mazeBluePrint[y, x - 1])
        {
            x--;
            printMv();

        }
        else if (irandom == mazeBluePrint[y, x + 1])
        {
            x++;
            printMv();
        }
        else if (irandom == mazeBluePrint[y - 1, x])
        {
            y--;
            printMv();
        }
        else
        {
            y++;
            printMv();
        }


    }
}

}

Your problem probably is the direction evaluation. Try this:

public static void randomMovement()
{
    Random randMove = new Random();

    int x = 1;
    int y = 1;

    int irandom = randMove.Next(4);
    Console.CursorLeft = x;
    Console.CursorTop = y;

    if (irandom == 0 && mazeBluePrint[y, x - 1] == 0)
    {
        x--;
        printMv();
    }
    else if (irandom == 1 && mazeBluePrint[y, x + 1] == 0)
    {
        x++;
        printMv();
    }
    else if (irandom == 2 && mazeBluePrint[y - 1, x] == 0)
    {
        y--;
        printMv();
    }
    else if (mazeBluePrint [y + 1, x] == 0)
    {
        y++;
        printMv();
    }
}

However, this code still has a lot of weaknesses (eg you could walk out of the boundaries of the mazeBluePrint array, which would result in an exception).

EDIT

If you want to move in the other direction if the first didn't work, you could try something like this:

public static void randomMovement()
{
    Random randMove = new Random();
    int x = 1;
    int y = 1;
    Console.CursorLeft = x;
    Console.CursorTop = y;
    while (true)
    {
        int irandom = randMove.Next(4);
        if (irandom == 0 && mazeBluePrint[y, x - 1] == 0)
        {
            x--;
            printMv();
            break;
        }
        else if (irandom == 1 && mazeBluePrint[y, x + 1] == 0)
        {
            x++;
            printMv();
            break;
        }
        else if (irandom == 2 && mazeBluePrint[y - 1, x] == 0)
        {
            y--;
            printMv();
            break;
        }
        else if (mazeBluePrint[y + 1, x] == 0)
        {
            y++;
            printMv();
            break;
        }
    }
}

However, this only moves one time, beginning from 1,1.
