returning largest int variable from object

Yes, you can iterate through an object's variables (i.e. its fields) using reflection.

Here's some example code:

using System;

using System.Reflection;

class MyClass

{

private int i;

protected int j;

public int k;

private long l;

public int I { get{ return i; } }

public MyClass(int i, int j, int k, long l)

{

this.i = i;

this.j = j;

this.k = k;

this.l = l;

}

class Test

{

static void Main()

{

MyClass mc = new MyClass(1, 3, 2, 4);

Type t = typeof(MyClass);

BindingFlags bf = BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic;

FieldInfo[] fia = t.GetFields(bf);

int max = Int32.MinValue;

string maxFieldName = null;

foreach(FieldInfo fi in fia)

{

if (fi.FieldType == typeof(int)) // 'l' will be excluded as type long, not int

{

int temp = (int)fi.GetValue(mc);

if (temp > max)

{

max = temp;

maxFieldName = fi.Name;

}

Console.WriteLine("The int field '{0}' has the maximum value of {1}", maxFieldName, max);

Console.ReadKey();

}
