    Radiobutton text to string

    Hello. I'm creating a simple program that randomizes answers in 3 radio buttons. The user will pick 1 answer. A button is pressed and the answer is checked against the real answer. I can't seem to be able to check the selected radiobutton text to the correct answer.

    I have the correct answer defined at a global level.

    I need to use a simple way to do this, so I figured this would be the best way:

    Code:
                RadioButton selectedRadioButton = (RadioButton)sender;
    
                decimal decGivenCorrectAnswer = selectedRadioButton.Text.ToString("N2");
    
                if (decGivenCorrectAnswer = decCorrectAnswer)
                {
    
                }
    
                else
                {
    
                }
    decCorrectAnswer is the global variable for the already calculated correct answer.

    Errors:

    Code:
    Error	1	The best overloaded method match for 'string.ToString(System.IFormatProvider)' has some invalid arguments
    Code:
    Error	2	Argument '1': cannot convert from 'string' to 'System.IFormatProvider'
    Code:
    Error	3	Cannot implicitly convert type 'decimal' to 'bool'
    Sorry. I'm new at this so I'm not understanding the way to check the selected radio button's text to a decimal variable.

    Are you sure you didn't mean:

    Code:
    if (decGivenCorrectAnswer == decCorrectAnswer)
    I'm pretty sure this explains the last 2 errors...

    Code:
    decimal decGivenCorrectAnswer = selectedRadioButton.Text.ToString("N2");
    You're converting a string to a string? I'm sure you're attempting to convert a string to a decimal instead:
    Code:
    decimal decGivenCorrectAnswer = decimal.Parse(selectedRadioButton.Text, System.Globalization.NumberStyles.Float);

    Well tried both ideas to fix the code. The first one helped a little, that was simple. The second one gave a lot of errors. I ended up linking the click events for all the radio buttons and throwing the following code into one of the check change events :

    Code:
                //Sender argument to a RadioButton data type.
                RadioButton selectedRadioButton = (RadioButton)sender;
    
                decChosenAnswer = decimal.Parse(selectedRadioButton.Text);
    decChosenAnswer is a global variable.

    I then put the following the the button to check for validation :

    Code:
                if (decChosenAnswer == decCorrectAnswer)
                {
                    MessageBox.Show("Hello");
                }
    
                else
                {
                    MessageBox.Show("Bye");
                }
    Thanks for the help.
