DateFormat extension help

Hi everyone, I've an entity data model added to my project and I'm populating a number of text-boxes with the datetime value from the EDM.

C#

txtFinancialYearFrom.Text = Convert.ToString(company.FinancialYearFrom);

But I'd like to try to write an extension method that takes that datetime value and reformats it into MMMMd format. Here's what I have so far:

C#

namespace ExtensionLibrary
{
    //Extension methods must be defined in a static class
    public static class DateFormatExtension
    {
        // This is the extension method.
        public static String MMMMdFormat(this DateTime date)
        {
            return new String(date.ToString(&quot;d MMMM&quot;));
        }
    }
}

at the minute this is giving me 2 errors:
Error 1 The best overloaded method match for 'string.String(char[])' has some invalid arguments
Error 2 Argument 1: cannot convert from 'string' to 'char[]'</pre>
Has anyone tried this before?

thank you OriginalGriff, here's what I have ended up with:

C#

namespace ExtensionLibrary
{
    //Extension methods must be defined in a static class
    public static class ExtensionLibrary
    {
        //This method handles any NULLABLE Datetime fields
        public static String FormatNULLDateTime(this DateTime? date)
        {
            if (date.HasValue)
                return ((DateTime)date).ToString("dd MMMM");
            else
                return "";
        }

        //This method handles non-NULLABLE Datetime fields
        public static String FormatDatetime(this DateTime date)
        {
            return ((DateTime)date).ToString("dd MMMM");
        }
    }
}

All you need to do is remove the "new String" bit:

C#

public static class MyExtensions
    {
    public static String MMMMdFormat(this DateTime date)
        {
        return date.ToString("d MMMM");
        }
    }
