从字符串中读取指定的子字符串
在TXT文本中, 
 [T1]123 
 [T2]123 
 [T3]123 
 [T1]123 
 [T2]123 
 [T3]123 
 ...     
 现已从TXT文本中将数据读读入一个string数据类型中, 
 求教如何实现: 
 1。统计属性[T1],[T2],[T3]各个出现的次数 
 2。累记属性[T1的数值   
------解决方案--------------------using System; 
 using System.Collections.Generic; 
 using System.Text; 
 using System.Text.RegularExpressions;   
 namespace ConsoleApplication1 
 { 
     class Program 
     { 
         static void Main(string[] args) 
         { 
             int[] counts = new int[] { 0, 0, 0 }; 
             int sumT3 = 0; 
             Regex regex = new Regex(@ "\[T(\d)\](\d+) "); 
             foreach (string line in System.IO.File.ReadAllLines( "TextFile1.txt ")) 
             { 
                 Match match = regex.Match(line); 
                 int index = Int32.Parse(match.Groups[1].Value); 
                 int value = Int32.Parse(match.Groups[2].Value); 
                 counts[index - 1]++; 
                 if (index == 3) 
                 { 
                     sumT3 += value; 
                 } 
             } 
             Console.WriteLine( "T1 {0} T2 {1} T3 {2} ",counts[0],counts[1],counts[2]); 
             Console.WriteLine( "Sum of T3 {0} ",sumT3); 
         } 
     } 
 } 
 我是不是太无聊了
