C# I can't get a field through reflexes

[Marcee]

There's a class:

public class ExampleClass
{
    private static readonly string ProtocolName = "prtclname";
}

I need to get his field. ProtocolName out of reflexia. I tried that:

var field = typeof(ExampleClass)
    .GetType()
    .GetField("ProtocolName", BindingFlags.NonPublic | BindingFlags.Static);

Something's coming back. null♪

var field = typeof(ExampleClass)
    //.GetType() - у System.Type тоже есть Type
    .GetField("ProtocolName", BindingFlags.NonPublic | BindingFlags.Static);
