我有下面的代码，它应该要求用户输入由#（如1#2#3##2等）分隔的各种整数。然后应该找到输入序列中具有重复的值并将其显示为“序列包含 2 个重复值”。

但是，我不确定用于分隔用户输入值的代码是否正确，因为它显示错误：

        // user input gets the input from the user 
       
        // regarding a line where integers are separated by # 
       
        String userInput;

        Console.WriteLine("Please enter single line containing a list of integers, separated by '#':");

        userInput = Console.ReadLine();

        // splitting the userInput into Array of Strings  
        if (userInput != null)
        {
            // …
