Invoking a method using reflection on a singleton object

Question

So I have the following:

public class Singleton
{

  private Singleton(){}

  public static readonly Singleton instance = new Singleton();

  public string DoSomething(){ ... }

  public string DoSomethingElse(){ ... }

}

Using reflection how can I invoke the DoSomething Method?

Reason I ask is because I store the method names in XML and dynamically create the UI. For example I'm dynamically creating a button and telling it what method to call via reflection when the button is clicked. In some cases it would be DoSomething or in others it would be DoSomethingElse.

Answer 1

Untested, but should work...

string methodName = "DoSomething"; // e.g. read from XML
MethodInfo method = typeof(Singleton).GetMethod(methodName);
FieldInfo field = typeof(Singleton).GetField("instance",
    BindingFlags.Static | BindingFlags.Public);
object instance = field.GetValue(null);
method.Invoke(instance, Type.EmptyTypes);
