示例1: Compare
/// <summary>
/// This IComparer class sorts by the fractional part of the decimal number.
/// </summary>
public class SpecialComparer : IComparer<decimal>
{
/// <summary>
/// Compare two decimal numbers by their fractional parts.
/// </summary>
/// <param name="d1">The first decimal to compare.</param>
/// <param name="d2">The second decimal to compare.</param>
/// <returns>1 if the first decimal's fractional part
/// is greater than the second decimal's fractional part,
/// -1 if the first decimal's fractional
/// part is less than the second decimal's fractional part,
/// or the result of calling Decimal.Compare()
/// if the fractional parts are equal.</returns>
