让streamreader从文本文件c＃中显示特定行

Question

我正在做一个测验。我有一个结构设置，保持4个不同的字符串，第一个是问题编号，第二个是问题级别，第三个是问题，第四个是问题答案。我将此结构的数据存储在文本文件中。测试的想法是，如果用户得到正确的问题，用户将在第一级开始测试，他们将升级到2级问题。我甚至无法显示第一个问题，这是我到目前为止应该显示问题的代码部分。在那一刻，控制台窗口中的光标反复闪烁。

 static void quiz(QuestionStruct[] _quiz)

        bool asked = true;
        int score = 0;
        int AmountAsked = 0;

        string level = "1";
        string ans;

        var pathToFile = @"..\..\..\Files\questions.txt";
        using (StreamReader sr = new StreamReader(pathToFile, true))
        {

            while (AmountAsked < 20 || score >= 50)
            {
                Console.Clear();
                int pos = 0;
                if (level == "1" && questions[pos].Level == level) /* when i take && questions[pos].Level == level out of this if statement I get text on the console window but it starts with the question number, then i press enter and i get the question level and so on. */
