copied!<p>If you can tolerate using factory methods (instead of the constructors MyClass you asked for) you could always do something like this:</p> <pre><code>class MyClass<T> { private readonly T _value; private MyClass(T value) { _value = value; } public static MyClass<int> FromInt32(int value) { return new MyClass<int>(value); } public static MyClass<string> FromString(string value) { return new MyClass<string>(value); } // etc for all the primitive types, or whatever other fixed set of types you are concerned about } </code></pre> <p>A problem here is that you would need to type <code>MyClass<AnyTypeItDoesntMatter>.FromInt32</code>, which is annoying. There isn't a very good way around this if you want to maintain the private-ness of the constructor, but here are a couple of workarounds:</p> <ul> <li>Create an abstract class <code>MyClass</code>. Make <code>MyClass<T></code> inherit from <code>MyClass</code> <strong>and nest it within <code>MyClass</code></strong>. Move the static methods to <code>MyClass</code>. This will all the visibility work out, at the cost of having to access <code>MyClass<T></code> as <code>MyClass.MyClass<T></code>.</li> <li>Use <code>MyClass<T></code> as given. Make a static class <code>MyClass</code> which calls the static methods in <code>MyClass<T></code> using <code>MyClass<AnyTypeItDoesntMatter></code> (probably using the appropriate type each time, just for giggles).</li> <li>(Easier, but certainly weird) Make an abstract type <code>MyClass</code> <strong>which inherits from <code>MyClass<AnyTypeItDoesntMatter></code></strong>. (For concreteness, let's say <code>MyClass<int></code>.) Because you can call static methods defined in a base class through the name of a derived class, you can now use <code>MyClass.FromString</code>.</li> </ul> <p>This gives you static checking at the expense of more writing.</p> <p>If you are happy with dynamic checking, I would use some variation on the TypeCode solution above.</p>
