C# Xamarin android Intents 和 readLine()

Question

我正在构建琐事应用程序并创建了表单活动问题。

因此，当用户按下右键时，它会重新打开活动。 我希望它会读取下一行而不是相同的行怎么办？

private void ShowQuestion()
{
    string content;
    AssetManager assets = this.Assets;
    StreamReader txt = new StreamReader(assets.Open("Test12.txt"), Encoding.GetEncoding("Windows-1255"));
    StreamReader csv = new StreamReader(assets.Open("Ans12.csv"), Encoding.GetEncoding("Windows-1255"));
    QuestionText.Text = txt.ReadLine();
    Button1.Text = txt.ReadLine();
    Button2.Text = txt.ReadLine();
    Button3.Text = txt.ReadLine();
    Button4.Text = txt.ReadLine();
    answer = csv.ReadLine();
}

private void Button1_Click(object sender, EventArgs e)
{
    if(answer == "א")
    {
        var intent = new Intent(this, typeof(Questions));
        StartActivity(intent);
    }
}

我认为你可以做类似的事情

    StreamReader txt = new StreamReader(assets.Open("Test12.txt"), Encoding.GetEncoding("Windows-1255"));

    protected override void OnCreate(Bundle bundle)
    {

        // ...

        // First line
        Button1.Text = txt.ReadLine();

    }

    private void Button1_Click(object sender, EventArgs e)
    {

        // other lines
        Button1.Text = txt.ReadLine();

    }

告诉我...
