Calling a method from Static class into a partial class to shuffle a list

Question

Using C# I am one peace of code from finishing main functionality of my program but have hit a brick wall and have searched for hours what to do.

My program is written in a partial class. I want to shuffle a list, an image list to be but I cant seem call a static method from within my partial class? I poached the method from Randomize a List<T> and it is exactly what I want to do. You may notice I have a shuffle method, but that method shuffles an array, not a list. I have added all my code as collapsed with only the methods of interest expanded. I tried creating a new class with the shuffle method inside but had no luck calling if in my partial class: I hope that isn't to much unnecessary code.

There is no reason you wouldn't be able to call into a static method from your partial class. Here are some things to check:

• Is the static method declared within your class? If not, you must specify the name of the class in which it is located. For example, Shuffler.Shuffle()
• If the method is in another class, make sure that the class and method are accessible -- set the class and method to public if they are not.
• Make sure you are passing the correct parameter types in the correct order.
