Call static method with reflection

Question

I have several static classes in the namespace mySolution.Macros such as

static class Indent{    
     public static void Run(){
         // implementation
     }
     // other helper methods
}

So my question is how it will be possible to call those methods with the help of reflection?

If the methods where NOT to be static then I could do something like:

var macroClasses = Assembly.GetExecutingAssembly().GetTypes().Where( x => x.Namespace.ToUpper().Contains("MACRO") );

foreach (var tempClass in macroClasses)
{
   var curInsance = Activator.CreateInstance(tempClass);
   // I know have an instance of a macro and will be able to run it

   // using reflection I will be able to run the method as:
   curInsance.GetType().GetMethod("Run").Invoke(curInsance, null);
}

I will like to keep my classes static. How will I be able to do something similar with static methods?

In short I will like to call all the Run methods from all the static classes that are in the namespace mySolution.Macros.

As the documentation for MethodInfo.Invoke states, the first argument is ignored for static methods so you can just pass null.

foreach (var tempClass in macroClasses)
{
   // using reflection I will be able to run the method as:
   tempClass.GetMethod("Run").Invoke(null, null);
}

As the comment points out, you may want to ensure the method is static when calling GetMethod:

tempClass.GetMethod("Run", BindingFlags.Public | BindingFlags.Static).Invoke(null, null);
