What is the best way to compare objects of value type N? So I want to do a String, Integer, DateTime, etc comparison depending on the type of the object.

A:
IEqualityComparer<T>
Where T is the type you want to compare.
IEqualityComparer(T) Interface (System.Collections.Generic)
...you could also fall back on Object.Equals()
and ValueType.Equals()

A:
static void Main(string[] args)
{
Console.WriteLine(Compare<int>(1, 3));
Console.WriteLine(Compare<string>("wil", "test"));
Console.WriteLine(Compare<DateTime>(DateTime.Now,
DateTime.Now.AddDays(-1)));
Console.ReadKey();
}
static int Compare<T>(T a, T b) where T : System.IComparable
{
System.IComparable comparer = a;
return comparer.CompareTo(b);
}
