copied!<p>I assume you mean static members of a class? In that case, you can do this:</p> <pre><code>public class MyClass { public static int MyInt = 12; public static MyOtherClass MyOther = new MyOtherClass(); } </code></pre> <p>Those static members are guaranteed to be instantiated before any class is instantiated.</p> <p>If you need complex logic, do it in a static constructor:</p> <pre><code>public class MyClass { public static int MyInt; public static MyOtherClass MyOther; static MyClass() { MyInt = 12; MyOther = new MyOtherClass(); } } </code></pre> <p><strong>Edit</strong></p> <p>Based on your edit, I'd say just assign the values to what they need to be before you instantiate the class, like so:</p> <pre><code>public class MyClass { public static int MyInt; public static MyOtherClass MyOther; } // elsewhere in code, before you instantiate MyClass: MyClass.MyInt = 12; MyClass.MyOther = new MyOtherClass(); MyClass myClass = new MyClass(); </code></pre> <p>That said, this method gives you no guarantee that MyInt and MyOther are set before MyClass is instantiated. It will work, but requires discipline before instantiating MyClass.</p> <p>One alternative pattern you might follow looks like this:</p> <pre><code>public class MyClass { private static int MyInt; private static MyOtherClass MyOther; private static bool IsStaticInitialized = false; public static InitializeStatic(int myInt, MyOtherClass other) { MyInt = myInt; MyOther = other; IsStaticInitialized = true; } public MyClass() { if(!IsStaticInitialized) { throw new InvalidOperationException("Static Not Initialized"); } // other constructor logic here. } } // elsewhere in your code: MyClass.InitializeStatic(12, new MyOtherClass()); MyClass myClass = new MyClass(); // alternatiavely: MyClass myClass = new MyClass(); // runtime exception. </code></pre>
