將一些字符串，如：?"bc",?"ad",?"ac",?"hello",?"xman",?"little",?"during","day"

排序的結果：“ad”，"ac"，“bc”，“during”，“day”，“hello”，“little”，“xman”

采用框架自帶的排序函數來調用自定義的Compare方法實現，代碼段如下所示：

?

class Program{static void Main(string[] args){string[] strArr = new string[] { "bc", "ad", "ac", "hello", "xman", "little", "during", "day"};List<string> strs = new List<string>();list.AddRange(strArr);/** Sort string by asc* result : “ad”，"ac"，“bc”，“during”，“day”，“hello”，“little”，“xman”*/list.Sort(new CompStr());foreach (string str in strs){Console.WriteLine(str);}Console.WriteLine("------------");//Sort string by desclist.Sort(new CompStrDesc());foreach (string str in strs){Console.WriteLine(str);}Console.ReadLine();}}public class CompStr : IComparer<string>{#region IComparer<string> Memberspublic int Compare(string x, string y){if (x.Length > 0 && y.Length > 0){if (x[0].CompareTo(y[0]) == 0){return -x.CompareTo(y);}}return x.CompareTo(y);}#endregion}public class CompStrDesc : IComparer<string>{#region IComparer<string> Memberspublic int Compare(string x, string y){if (x.Length > 0 && y.Length > 0){if (x[0].CompareTo(y[0]) == 0){return x.CompareTo(y);}}return -x.CompareTo(y);}#endregion}
