How to check that MethodInfo matches Delegate of generic type T, where T is either Action or Func?

Question: How to check that MethodInfo matches Delegate of type T, where T is either Action or Func?

Code sample with the use case of getting all static functions out of an Assembly which should match the Delegate of type T:

void AddScriptFunctions<T>(Assembly assembly, Dictionary<string, T> funMap) where T: class
{                                                            
    foreach(Type type in assembly.GetTypes()) 
    {                
        var methods = type.GetMethods(BindingFlags.Public | BindingFlags.Static);
        foreach(MethodInfo method in methods) 
        {                    
            // How to check that MethodInfo can be converted into delegate of type T
            // where T is Func<...> or Action<...>
            if( ........ )
            {
                var function = (T)(object)Delegate.CreateDelegate(typeof(T), method);                    
                funMap.Add(method.Name.ToLower(), function);        
            }                
        }

    }        

Function invocation examples:

var functions = new Dictionary<string, Func<int, int>>();
AddScriptFunctions(Assembly.GetExecutingAssembly(), functions);

var functions2 = new Dictionary<string, Action>();
AddScriptFunctions(Assembly.GetExecutingAssembly(), functions2);

Note: without enclosing Delegate.CreateDelegate into an try/catch block.
