        {StringComparison.CurrentCulture, Function() StringComparer.CurrentCulture},
        {StringComparison.CurrentCultureIgnoreCase, Function() StringComparer.CurrentCultureIgnoreCase},
        {StringComparison.InvariantCulture, Function() StringComparer.InvariantCulture},
        {StringComparison.InvariantCultureIgnoreCase, Function() StringComparer.InvariantCultureIgnoreCase},
        {StringComparison.Ordinal, Function() StringComparer.Ordinal},
        {StringComparison.OrdinalIgnoreCase, Function() StringComparer.OrdinalIgnoreCase}
    }

Usage:

Dim comparer As StringComparer = map(comparison)()
