    <p>Enumerations in the CLR are simply named constants. The underlying type must be integral. In Java an enumeration is more like a named instance of a type. That type can be quite complex and - as your example shows - contain multiple fields of various types.</p> <p>To port the example to C# I would just change the enum to an immutable class and expose static readonly instances of that class:</p> <pre><code>using System; using System.Collections.Generic; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Planet planetEarth = Planet.MERCURY; double earthRadius = pEarth.Radius; // Just threw it in to show usage double earthWeight = double.Parse("123"); double earthMass = earthWeight / pEarth.SurfaceGravity(); foreach (Planet p in Planet.Values) Console.WriteLine($"Your weight on {p} is {p.SurfaceWeight(mass)}"); Console.ReadKey(); } } public class Planet { public static readonly Planet MERCURY = new Planet("Mercury", 3.303e+23, 2.4397e6); public static readonly Planet VENUS = new Planet("Venus", 4.869e+24, 6.0518e6); public static readonly Planet EARTH = new Planet("Earth", 5.976e+24, 6.37814e6); public static readonly Planet MARS = new Planet("Mars", 6.421e+23, 3.3972e6); public static readonly Planet JUPITER = new Planet("Jupiter", 1.9e+27, 7.1492e7); public static readonly Planet SATURN = new Planet("Saturn", 5.688e+26, 6.0268e7); public static readonly Planet URANUS = new Planet("Uranus", 8.686e+25, 2.5559e7); public static readonly Planet NEPTUNE = new Planet("Neptune", 1.024e+26, 2.4746e7); public static readonly Planet PLUTO = new Planet("Pluto", 1.27e+22, 1.137e6); public static IEnumerable&lt;Planet&gt; Values { get { yield return MERCURY; yield return VENUS; yield return EARTH; yield return MARS; yield return JUPITER; yield return SATURN; yield return URANUS; yield return NEPTUNE; yield return PLUTO; } } public string Name { get; private set; } public double Mass { get; private set; } public double Radius { get; private set; } Planet(string name, double mass, double radius) =&gt; (Name, Mass, Radius) = (name, mass, radius); // Wniversal gravitational constant (m3 kg-1 s-2) public const double G = 6.67300E-11; public double SurfaceGravity() =&gt; G * mass / (radius * radius); public double SurfaceWeight(double other) =&gt; other * SurfaceGravity(); public override string ToString() =&gt; name; } } </code></pre>

    1. CODoing that means you cannot use a for-each loop on the enums.

    3. COIt's this sort of type-safe enum that us poor people forced to use Java 1.4 and below have to implement...Java 5's enums are perhaps the best feature of Java 5+, especially since they can be used in switch statements.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
