ConvertCsvToXml does not exist in the current context

private void button2_Click(object sender, EventArgs e)
    {

        //read in file data and calculate record number
        string csv = File.ReadAllText("File-Path");
        int testing = 1;

        XDocument doc = ConvertCsvToXml(csv, new[] { "\t" });

        //create array of record number
        WebService.Function[] xxx = new WebService.Function[1];

        recordAmount = 0;

Hi there for some reason in the above code the ConvertCsvToXml line is bringing back an exception saying it does not exist, and the intelisense brings up n开发者_StackOverflowothing after typing XDocument.

What can I do to resolve this? There are no errors in my code other than this!

Thanks for your time.

You'll have to define the ConvertCsvToXml method in the same class as the button2_Click method.
