C# Get dictionary from DLL

I have class library project, where I have some methods and dictionaries

public static Dictionary<string, Instruments> globalInstruments;
public static Dictionary<string, WidgetInfo> _MinMaxStorageMinute;
public static Dictionary<string, WidgetInfo> _MinMaxStorageFive;
public static Dictionary<string, WidgetInfo> _MinMaxStorageFifteen;
public static Dictionary<string, WidgetInfo> _MinMaxStorageHalfHour;
public static Dictionary<string, WidgetInfo> _MinMaxStorageHour;
public static Dictionary<string, WidgetInfo> _MinMaxStorageFourHour;
public static Dictionary<string, WidgetInfo> _MinMaxStorageDay;
public static Dictionary<string, WidgetInfo> _MinMaxStorageWeek;

How can I get this dictionaries dynamically? I try to do this

Assembly asm = Assembly.LoadFrom(@"C:\DFListener.dll");
Type type = asm.GetType("DFListener.Listener");
FieldInfo f = type.GetField("globalInstruments");

But how can I get access to dictionary values and keys?

EDIT

When I use same namespace I get this error

You're currently just getting the field - you need to get the value of the field using the GetValue method:

var dictionary = (Dictionary<string, WidgetInfo>) f.GetValue(null);

Here the null argument is because it's a static field. If it were an instance field, you'd pass a target reference in, to specify the instance to get the value from.
