如果觉得分数不够，我还可以追加，希望高手帮忙！

Answer 1

见两个临时StringBuilder sbOrdered和sbTmp，逐行取进行比较，如果要是 "看见飞过海扩大计划发" 的话直接Append到sbOrdered，如果不是则Append到sbTmp，最后把sbTmp Append到sbOrdered。
排序完成

Answer 2

首先要把这个文本文件读到List里面
然后排序这个List
然后把List写会文件读写文件自己搞定吧
读的时候每行按照空格去Split成一个字符串数组
至于排序实现一下ICompare接口就可以了ICompare如下
using System.Collections;
using System;
using System.Collections.Generic;namespace testApplication1
{
/// <summary> 
/// IntCompare
/// </summary> 
public class ListCompare : IComparer<string[]> 
{
        public ListCompare() 
{
}        #region IComparer<string[]>        public int Compare(string[] x, string[] y)
        {
            string temp1 = x[2];
            string temp2 = y[2];
            return temp1.CompareTo(temp2);//如果倒序颠倒位置~~~~这里可以自定义需要排序的字段
        }        #endregion
    }
}
调用方法如下
List<string[]> test = new List<string[]>();
            test.Add(new string[] { "324234", "1", "666", "111" });
            test.Add(new string[] { "324234", "1", "000", "111" });
            test.Add(new string[] { "324234", "1", "222", "111" });
            test.Add(new string[] { "324234", "1", "444", "111" });
            test.Sort(new ListCompare());
            foreach (string[] temp in test)
            {
                Console.WriteLine(temp[2]);
            }

以下三种都是可以的，没有特殊要求，我的要求就是把主记录相同的排在一起，从记录跟随其后，如：
