How to do it...

The process of building an N-Gram predictor is divided into five big steps, as follows:

1. Create the general class within a file that has the same name:

using System.Collections; 
using System.Collections.Generic; 
using System.Text; 
 
public class NGramPredictor<T> 
{ 
    private int nValue; 
    private Dictionary<string, KeyDataRecord<T>> data; 
}

2. Implement the constructor for initializing the member variables:

public NGramPredictor(int windowSize) 
{ 
    nValue = windowSize + 1; 
    data = new Dictionary<string, KeyDataRecord<T>>(); 
} 

3. Implement a static function for converting a set of actions into a string key:

public static string ArrToStrKey(ref T[] actions) { StringBuilder builder = new StringBuilder(); foreach (T a in actions) { builder.Append(a.ToString()); ...
