You can handle a wrong input with try catch:

try{
BankAccount b = new BankAccount();
b.Deposit( Convert.ToInt32(Console.ReadLine()));
b.Withdraw( Convert.ToInt32(Console.ReadLine()));
Console.WriteLine("Your balance :"+(b.GetBalance()));

}catch(Exception e)
{
Console.WriteLine("Wrong Input! ");
}
