Radio Button Value from Database C#

I am trying to get my program to read a value from a particular cell in my Access database so that I can assign that value to the text property of a radio button. I am however getting an error I can't figure out the problem to. This is my code:

private void WindowsAnalysisQuiz_Load(object sender, EventArgs e)
{
    //declare connection string using windows security
    string cnString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\Users\\Hannah\\Desktop\\WindowsAnalysisQuiz.accdb";

   //declare Connection, command and other related objects
   OleDbConnection conGet = new OleDbConnection(cnString);
   OleDbCommand cmdGet = new OleDbCommand();
   try
   {
       //open connection
       conGet.Open();

       cmdGet.CommandType = CommandType.Text;
       cmdGet.Connection = conGet;
       //cmdGet.CommansText = "SELECT 
       cmdGet.CommandText = "SELECT Question FROM WindowsAnalysisQuiz ORDER BY rnd()";

       OleDbDataReader reader = cmdGet.ExecuteReader();
       reader.Read();
       label1.Text = reader["Question"].ToString();
       radioButton.Text = cnString["Quiz"].Rows[0]["Correct Answer"].ToString();
       radioButton1.Text = reader["Answer2"].ToString();
       radioButton2.Text = reader["Answer3"].ToString();
       radioButton3.Text = reader["Answer4"].ToString();
       conGet.Close();
   }
}

I am having the problem with the line beginnin开发者_Go百科g with radioButton.Text. Apparently it has some invalid arguments and argument 1 cannot convert from string to int

It looks like you are using several different RadioButtons, when you might really want a RadioButtonList.

If you have a RadioButtonList, it is easy to bind something to it, in essence create a list (from your database or whatever) and then bind this to the radio button list..something like

        var de = new List<string>();
        de.Add("1");
        de.Add("2");
        de.Add("3");

        RadioButtonList1.DataSource = de;
        RadioButtonList1.DataBind();

Shouldn't your code be something like the following:

radioButton.Text = reader["Correct Answer"].ToString();

And change your select statement to:

cmdGet.CommandText = "SELECT Question, [Correct Answer], Answer2, Answer3, Answer4 FROM WindowsAnalysisQuiz ORDER BY rnd()";
