Store an operator in a variable

Question

Is there a way to store an operator inside a variable? I want to do something like this (pseudo code):

void MyLoop(int start, int finish, operator op)
{

I tried a different approach, using a class that defines operators and accessing via reflection - i.e. you can store your operators as strings. This allows for relational operators as well.

class Program
{
    static void Main(string[] args)
    {
        Operators ops = new Operators();
        object result = ops.Use("LessOrEqual", new object[] {3,2}); // output: False
        Console.WriteLine(result.ToString());

        result =  ops.Use("Increment", new object[] {3}); // output: 4
        Console.WriteLine(result.ToString());
        Console.ReadKey();
    }
}

public class Operators
{
    public object Use(String methodName, Object[] parameters)
    {
        object result;
        MethodInfo mInfo = this.GetType().GetMethod(methodName);
        result = mInfo.Invoke(this, parameters); // params for operator, komma-divided
        return result;
    }


    public bool LessOrEqual(int a, int b)
    {
        if (a <= b)
        {
            return true;
        }
        else
        {
            return false; 
        }  
    }

    public int Increment(int a)
    {
        return ++a;
    }
}
