Get user-created methods

Question

I have a method that lists the methods that a given object has, I want to take only the methods created by the user, in this case: Add and Subtract.

What this method returns to me:

Generic Class

public class Generico
{
    public object Objeto { get; set; }

    public string[] ListarMetodos()
    {
        var m = Objeto.GetType().GetMethods();
        string[] metodos = new string[m.Length];

        for (int i = 0; i < m.Length; i++)
            metodos[i] = String.Concat(i, " [+] ", m[i].Name, "\n");
        return metodos;
    }
}

Class Example

public class Calculadora
{
    public int x { get; set; }
    public int y { get; set; }

    public Calculadora() { }

    public int Somar()
    {
        return this.x + this.y;
    }

    public int Subtrair()
    {
        return this.x - this.y;
    }
}

Answer 1

You can check which type is the method declaration using the property DeclaringType of MethodInfo, so you can filter the way you want:

public string[] ListarMetodos()
{
    var t = Objeto.GetType();
    return t.GetMethods()
        .Where(mi => mi.DeclaringType == t)
        .Where(x => !x.IsSpecialName)
        .Select((mi, i) => i + " [+] " + mi.Name)
        .ToArray();
}

Answer 2

Use:

var m = Objeto.GetType().GetMethods(BindingFlags.Instance | BindingFlags.Public | BindingFlags.DeclaredOnly).Where(x => !x.IsSpecialName).ToArray();
