How can I test if an enum is defined or not whilst ignoring case?

Question

The following generic static method takes a string and returns an enum.

It nicely ignores case since I set the ignoreCase parameter to true.

However, I also want to test if the enum exists, but the enum.IsDefined method to do this doesn't seem to have an ignoreCase parameter.

How can I test if the enum is defined or not and at the same ignore case?

using System;

namespace TestEnum2934234
{
    class Program
    {
        static void Main(string[] args)
        {
            LessonStatus lessonStatus = StringHelpers.ConvertStringToEnum<LessonStatus>("prepared");
            ReportStatus reportStatus = StringHelpers.ConvertStringToEnum<ReportStatus>("finished");

            Console.WriteLine(lessonStatus.ToString());
            Console.WriteLine(reportStatus.ToString());
            Console.ReadLine();
        }
    }

    public static class StringHelpers
    {
        public static T ConvertStringToEnum<T>(string text)
        {
            if (Enum.IsDefined(typeof(T), text)) //does not have ignoreCase parameter
                return (T)Enum.Parse(typeof(T), text, true);
            else
                return default(T);
        }
    }

    public enum LessonStatus
    {
        Defined,
        Prepared,
        Practiced,
        Recorded
    }

    public enum ReportStatus
    {
        Draft,
        Revising,
        Finished
    }
}

public enum MyEnum
{
    Bar,
    Foo
}

class Program
{
    static void Main(string[] args)
    {
        var containsFoo = Enum.GetNames(typeof(MyEnum)).Any(x => x.ToLower() == "foo");
        Console.WriteLine(containsFoo);
    }
}
