Add breaks to the end of case "Rock", case "Scissors" and case "Paper"::

switch (Player1)
{
    case "Rock":
        switch (Player2)
        {
            case "Rock":
                Console.WriteLine("Draw");
                break;
            case "Scissors":
                Console.WriteLine("Win Player1");
                break;
            case "Paper":
                Console.WriteLine("Win Player2");
                break;
        }
        switch (Player1)
        {
            case "Scissors":
                switch (Player2)
                {
                    case "Rock":
                        Console.WriteLine("Win Player2");
                        break;
                    case "Scissors":
                        Console.WriteLine("Draw");
                        break;
                    case "Paper":
                        Console.WriteLine("Win Player1");
                        break;
                }
                switch (Player1)
                {
                    case "Paper":
                        switch (Player2)
                        {
                            case "Rock":                       
                                Console.WriteLine("Win Player1");
                                break;
                            case "Scissors":
                                Console.WriteLine("Win Player2");
                                break;
                            case "Paper":
                                Console.WriteLine("Draw");
                                break;
                            }
                    break;  //<---
                }
            break; //<---
         }
    break;  //<---   
}

Switch statement's cases should have break;, throw, goto, or return to exit after case is done. This isn't true only if you have cases stacked like so:

switch(statement)
{
    case 1:
    case 2:
    case 3:
        DoSomething();
        break;
}

I see an error CS8070 . How i can fix the error?
