+Here's the example program:
+
+using System;
+using System.Collections.Generic;
+
+struct ComparablePair<T,U> : IComparable<ComparablePair<T,U>>
+  where T : IComparable<T> 
+  where U : IComparable<U> {
+  public readonly T Fst;
+  public readonly U Snd;
+  
+  public ComparablePair(T fst, U snd) {
+    Fst = fst; Snd = snd;
+  }
+  
+  // Lexicographic ordering
+  public int CompareTo(ComparablePair<T,U> that) {
+    int firstCmp = this.Fst.CompareTo(that.Fst);
+    return firstCmp != 0 ? firstCmp : this.Snd.CompareTo(that.Snd);
+  }
+
+  public override String ToString() {
+    return "(" + Fst + ", " + Snd + ")";
+  }
+}
+
+// Sorting soccer world champions by country and year
+
+class MyTest {
+  public static void Main(String[] args) {
+    List<ComparablePair<String,int>> lst 
+      = new List<ComparablePair<String,int>>();
+    lst.Add(new ComparablePair<String,int>("Brazil", 2002));
+    lst.Add(new ComparablePair<String,int>("France", 1998));
+    lst.Sort();
+    foreach (ComparablePair<String,int> pair in lst) 
+      Console.WriteLine(pair);
+  }
+}
