how to prevent getmethods from retrieve a specific method

I have a static class with private functions, I want to get all functions except one. I tried using Ignorecase but i get an overload exception... I do it exactly like many examples online but I get an error and I dont know why...am I missing something?

//Example

   static MethodInfo[] allFuncs ;
  static Type myType = typeof(myClass);        
  allFuncs = myType.GetMethods("innerFunction", BindingFlags.IgnoreCase|BindingFlags.NonPublic | BindingFlags.Static );
